    The invention relates to a target approximation method with a long-range optical device.
    Long-range optical devices, in particular for hunting, are optimized with regard to their imaging properties aimed at the target, in particular with regard to the distances to be found during hunting. This is important if the long-range optical device is a rifle scope of a hunting rifle. The long-range optical device can also be a pair of binoculars or a telescope (generally also a telescope with observation optics) in order to aim at a distant target. Modern riflescopes or binoculars, in particular modern long-range optical devices, usually also have a distance measuring device. This distance measuring device is preferably arranged on the long-range optical device in such a way that the measuring direction or the measuring beam corresponds exactly with the viewing direction, in particular with the optical axis of the long-range optical device. This ensures that when a target is sighted by the long-range optical device, even the measuring axis for determining the distance between the optical device and the target, exactly coincides with the line of sight and thus no target errors and incorrect measurements occur.
    Modern long-range optical devices also have an orientation determination device in order to be able to determine or indicate the viewing direction in space, in particular in relation to the cardinal points and the horizontal plane.
    If a target (point-of-interest - POI) is sighted and the wearer of the long-range optical device wants to reach the target position, the current position is known, for example, from US 9,068,800 B2 and also US 9,335,121 B2
    2/39
    N2016 / 25300-AT-00 of the long-range optical device. Based on the determined distance and
    A digital map is updated with directional information, and the map is kept up-to-date as the wearer of the long-range optical device moves. The current position of the wearer or the long-range optical device is determined by means of a satellite-based global positioning system (GPS).
    From DE 201 11 501 U1 a GPS-based position determination device is known which updates a display, in particular a map display, on the basis of the determined position and a distance and direction to the destination.
    Another similar embodiment of such a device is shown in US 2012/0109577 A1, US 5,825,480 A and US 8,314,923 B2.
    The problem that arises with the prior art documents is that these systems rely on a global positioning system, in particular this is a satellite-based positioning system. When moving off-road, it can often happen due to local conditions that a clear view upwards is restricted and therefore too few satellites can be reached for a reliably accurate position determination. It can also happen that the signal quality is insufficient and the location accuracy is accordingly imprecise. Although the satellites move continuously, it is impractical for a user of a long-range optical device to wait for a sufficient number of satellites to appear in order to be able to carry out a sufficiently precise position determination. Furthermore, since in many cases the absolute position of the wearer of the long-range optical device and also the absolute position of the target are of little or no importance, an absolute position determination is usually not necessary.
    Furthermore, in the systems known from the prior art, the position of the carrier or more precisely, the long-range optical device, is determined continuously and cyclically by means of the global position determination system and the map display is updated. This means an unnecessary expenditure on equipment and is particularly due to the associated increased energy consumption
    3/39
    N2016 / 25300-AT-00 disadvantageous with regard to the longest possible autonomous operation. Another disadvantage is that position determination systems, in particular satellite-based systems, require a clear line of sight to the sky in order to be able to carry out the position determination. However, this is often not the case in the terrain, so that the position determination can then only be carried out very imprecisely or not at all. During hunting and / or observation activities, the hunter / observer may have to take a protected or covered position and the required line of sight upwards is missing or restricted. After leaving the position, the observer would then have to wait until a stable position determination has been achieved, which may takes some time. Or, which would be significantly more unfavorable, the observer would have to start with an inexactly determined position, or move into an area where there is sufficient line of sight upwards. In practical use, however, this has decisive disadvantages, since in any case time is lost for the approach to the goal.
    The object of the invention is to find a method for a modern long-range optical device which uses or uses existing systems of a long-range optical device, in particular a system for determining the distance to a target and an orientation of the long-range optical device. Based on a determined distance information and a determined orientation, a dependency on additional systems or services known from the prior art is to be avoided. The object of the invention is therefore in particular to enable an immediate start of the approach to a destination only with existing information.
    In this context, the goal is not only a goal in the hunting sense (animal), but any scene or object of particular interest ('point of interest' POI) that can be observed by an observer with a long-range optical device, such as striking landscapes or geological locations Formations, sights, buildings or people.
    This object is achieved by a method according to the claims.

    N2016 / 25300 AT-00
    The method according to the invention relates to a target approximation method with a long-range optical device, which long-range optical device has observation optics, a distance measuring device and an orientation determination device. The method comprises an adaptation step, in which an observation position is used to aim at an intermediate position, a reference position, with a reference distance and a reference angle to the target at a target position, and a difference angle between an absolute direction and a reference direction of the long-range optical device is determined by means of the alignment determination device. A difference distance from the intermediate position to the reference position is determined by means of the distance measuring device, and a target distance and a target angle are determined from a geodetic computing module, from the reference distance and the difference distance, and from the reference angle and the difference angle.
    The particular advantage of this method is that the approach to the target can begin or start again from any intermediate position along the path from a starting position to the target at the target position. In particular, it is provided according to the claim that a reference distance and a reference angle to the target are known from a reference position which can be sighted from the intermediate position. It would be advantageous if, when approaching the destination, a starting point, for example the starting position, were visible all the way and thus can be targeted. Along the way to the destination, the situation may arise due to local conditions that this starting point can no longer be seen or targeted. In such a case, the embodiment according to the invention also ensures that it is possible to reliably approach the target at any time by using a reference position as a new reference point for determining the direction of movement to the target. This reference position can be formed, for example, by a landscape mark that is visible from afar or by a structural feature.
    Another advantage of this method also lies in the fact that by means of devices, in particular a distance measuring device and an orientation determining device, which are present on modern long-range optical devices,
    5/39
    N2016 / 25300-AT-00 a destination can be approached without the need for additional navigation systems. Such additional systems lead to additional technical outlay on equipment and may not function reliably when moving in the field because, for example, the required unobstructed view upwards is not given due to spatial restrictions.
    According to a further development, the method has a referencing step. In this referencing step, the observation optics aim at a second position from one position, the distance and the angle to the target at the target position being known from one of the positions. A difference distance between the two positions is determined by means of the distance measuring device, and a first angle between an absolute direction and a reference direction of the long-range optical device is determined by means of the orientation determining device. The geodetic computing module determines the distance and the angle to the target at the target position of the other position from the difference distance and the first angle, as well as from the known distance and angle to the target at the target position from one position. This determined distance and this angle are set as the reference distance and reference angle of the previously undetermined position, so that this position thus becomes a reference position. In particular, at least one starting position is determined by measurement to the target position as a reference position after these steps. This further development enables a user to be able to determine any position as a reference position or to determine a position measured thereby as a new reference position. In particular, the starting position is thus determined as the reference position.
    According to a further development, it is provided that the long-range optical device furthermore has an inclination measuring device, a difference in height angle being determined in the adaptation step, when aiming at the reference position from the intermediate position, and a target height angle is determined by the geodetic computing module from a reference height angle and the difference in height angle, and this when calculating the target distance and the target angle with consider 6/39
    N2016 / 25300-AT-00. If the height difference between the start and the target position is small and the terrain between the start and target position is largely flat, disregarding the target height angle would cause a negligible error. In the case of a large difference in height and / or hilly terrain, the objective consideration of the height angle or the differential height angle leads to a significant improvement in the approximation accuracy.
    In this regard, according to a further development, it is also provided that the long-range optical device furthermore has an inclination measuring device, a difference in height angle being determined when aiming at a position in the referencing step, and a reference target height angle is determined by the geodetic computing module from the difference in height angle and a known height angle of a position. The advantages of considering a height difference have already been described.
    A further development also consists in the fact that the determined target distance, the determined target angle and / or the determined target height angle are displayed on a display means, wherein both numerals and graphic indicators can serve to illustrate the numerical values. In this regard, it is also advantageous if the display means is arranged in or on the long-range optical device, preferably in the observation optics. This further development has the particular advantage that the determined direction to the destination is displayed or displayed directly in the user's viewing area. It is particularly advantageous if the display means is arranged in the observation optics, because then the user is shown the information directly when looking at the targeted position and therefore does not need to set the telephoto device away from the eyes.
    An advantageous development consists in that the adaptation step is carried out again at a further intermediate position that is spatially distanced from the previous intermediate position, in which the intermediate position is determined equal to the starting position, the determined target distance to the first distance and the target angle to the first angle, and that, if appropriate, the Differenzhö7 / 39
    N2016 / 25300-AT-00 angle to the first height angle. This corresponds to an iterative process in which the target is approached piece by piece. Especially when moving in rough terrain, a direct route to the destination is sometimes not possible, but the destination can only be reached via one or more intermediate positions. With the subject development, the correct direction and distance to the target can always be determined along the path and can be displayed to the user of the long-range optical device.
    According to a further development, it is further provided that the adaptation step is carried out again at a further intermediate position that is spatially distanced from the previous intermediate position. If the situation on the way to the target position shows that it is no longer possible to sight the starting position, this development can also be used to switch from the starting position as the original starting reference to an explicit reference point as the starting reference. It is also possible that the situation arises on the way that the starting position can be targeted again. With this development, it is also possible to switch from an explicit reference position back to the starting position as a starting reference.
    A further development is also advantageous, according to which the orientation determination device is formed by a compass, and the north direction is defined as the absolute direction. A compass, in particular an electronic compass, is now very compact, sufficiently precise and inexpensive, so that such a compass can be very easily integrated into a long-range optical device. The use of a compass with the north direction as the absolute direction has the further advantage that such a device always, and in particular without regular adjustment, provides a globally valid absolute orientation as a reference orientation. Since a relative and no absolute alignment is no longer necessary in accordance with the objective method in question, the requirements for the alignment determination device with regard to absolute measurement accuracy are not too high; good repeatability is important.
    8/39
    N2016 / 25300 AT-00
    If the long-range optical device moves while approaching the target, it will occur due to local conditions that the current direction of movement deviates from the target direction determined at the start or intermediate position. According to a further development, it is therefore provided that the absolute direction is determined continuously or cyclically by the orientation determination device and is displayed on the display means. Thus, the wearer of the long-range optical device always receives a current representation of the absolute direction and can use basic orientation knowledge to estimate the direction to the target.
    A further development also consists in the fact that the distance measuring device has an illuminant for the directed emission of pulsed light, in particular a laser or an LED. By means of the distance measuring device, the target distance and the target angle, and possibly the target elevation angle, or in a second case the second distance information, the first distance and the first angle, and optionally the first elevation angle, are optically transmitted to a remote site via a Transfer modulation of the light of the distance measuring device. The relative distance and the relative angle between the transmitter and receiver are also transmitted or automatically determined during the transmission. This makes it possible to determine the relative location from the receiver to the transmitter using the geodetic / trigonometric computing module on the basis of distance and angle. The relative location of the recipient is important in order to determine the relative location of the destination in relation to the recipient from the transmitted data. The long-range optical device is located at the intermediate position (case I) or the starting position (case II), and the remote station is at a transfer position that is spatially distant from it. This advantageous further development makes it possible to transmit the target position or the adapted direction to the target / POI to one or more remote stations, in particular to another remote optical device that supports the method in question. When moving off-road, it can happen that a second person as the bearer of the remote site is in a more favorable position and / or closer to the destination. With this development, the target information can be transmitted to this second person, so that this person can then carry out or continue to approach the target
    9/39
    N2016 / 25300-AT-00 can. In the field, because of the distance or due to a requirement for silence, for example in a hunting stalk, communication between the people and in particular the transmission of the target position can be difficult. With this development, it is advantageously achieved that the target position or the direction to the target can be transmitted reliably and to the exclusion of communication errors. Furthermore, the first person or first long-range optical device is understood to mean the person or device that / which has targeted the target and transfers the directional information to the target to the second person, the second device or the remote station. Of course, the handover between the long-range optical device and the remote station takes place optically by means of the distance measuring device.
    If the receiver (s) are in the immediate vicinity of the transmitter, the determination of the relative position between the transmitter-receiver can be omitted and the transmitter position can be continued. This means that only the distance and the angle of the transmitter to the target have to be transmitted. In this case it is also possible or provided that the target position by means of wireless communication between the different devices such as. Bluethooth or WiFi is transmitted. Among other things, this is advantageous if, for example, a group or even a single observer is forwarded to the target position of a particular target by another observer (guide) in the vicinity, making it easier for observers to find the same target more easily.
    When the target position or the direction to the target is transmitted to a second person at a transfer position, the change in location means that the direction and distance to the target have to be recalculated. Therefore, according to a further development, it is provided in the first case (with reference to the previous explanation and definition of the term) for the transmitted first directional information, the target distance as the reference distance and the target angle as the reference angle, and furthermore the target height angle as the reference height angle becomes. The adaptation step is then carried out again, the current position being the starting position
    10/39
    N2016 / 25300 AT-00
    Intermediate position of the long-range optical device is determined. This variant corresponds to the case where the first person carried out the target acquisition and at least one adaptation step. For example, the approach path may result in a second person in a more favorable position and the target position is transferred to the latter. In the second case, the remote station carries out the adaptation step for the transmitted second direction information or carries it out again. This is to be understood to mean that only the target position determination step is carried out by the first person and then the determined target position is transmitted to the second person.
    A further development also consists in the fact that the display means is formed by a mobile data terminal and a wireless communication link exists between the far-optical device and the mobile data terminal, via which the determined target distance and the determined target angle, and possibly the target height angle, are transmitted. A mobile data terminal can be formed, for example, by a smartphone, tablet, smart watch or the like. The advantage of this design is that such mobile data terminals have good technical equipment and in particular have at least one display means and mostly a plurality of different communication interfaces. Furthermore, such devices are widespread and the majority are always carried. The high-frequency communication connection cannot finally be, for example, Bluetooth, ZigBee, WLAN, NFC or an equivalent communication system.
    A further development is particularly advantageous, according to which the mobile data terminal also has an orientation determination device, in particular an electronic compass, an orientation angle between the orientation of the data terminal and the absolute direction being determined by the data terminal by means of the orientation determination device of the data terminal. The transmitted target angle is transformed to the alignment angle and the difference angle determined is displayed on the display means. Thus, the user can be given a visual representation of the direction via the display means
    11/39
    N2016 / 25300-AT-00 the destination is. If this orientation determination is carried out cyclically or triggered manually, the user always has up-to-date information on the direction of the target on the target approach path.
    Another possible embodiment also consists in the data terminal device having an acceleration sensor which detects a movement of the data terminal device and transmits it as a motion vector to the geodetic computing module, which continuously or cyclically, from the reference distance and the reference angle, as well as the difference distance and the difference angle, and, if appropriate the difference in elevation angle and the first elevation angle, the target distance and the target angle and, if applicable, the target elevation angle. With this development, the direction to the target, in particular the distance and the target angle, can be adapted during the movement based on the determined movement information and made available to the user.
    A further development also consists in the fact that the display means is arranged on the observation optics in such a way that the representation of the target distance and the target angle is superimposed on the beam path of the observation optics. This development has the advantage that the wearer of the long-range optical device does not need to take any additional action in order to have the determined values displayed. Immediately after the target position determination step or the adaptation step, the wearer of the long-range optical device is shown the information directly in his field of vision. The direction can be displayed, for example, by specifying a numerical value of the target angle, by displaying an arrow or by using alignment marks.
    A further development also consists in the fact that the target distance and the target angle and possibly the target height angle are displayed as one of the group direction arrow, scale range, alignment vector, bar display, alphanumeric display on the display means. Directional arrows can be shown on the edge or in the middle and, for example, by varying the size and / or display intensity, indicate the measure in which direction and / or how far the long-range optical device has to be pivoted in order to aim at the target. An alignment vector er12 / 39
    N2016 / 25300-AT-00 enables a combined display as a single directional arrow. The rotation relative to a defined direction describes how the long-range optical device must be aligned. The distance can be visualized over the length of the vector. A bar display can function similarly to the directional arrows. In particular, the bars of the reticle (for example reticle 8) can represent the directional information by varying the filling. A bar display can also be designed or function in a similar manner. These training courses allow a qualitative representation of the target direction, which the user can read and grasp at a glance. An alphanumeric representation allows the target information to be given in almost any detail, but this also requires a reading and processing step by the user. Details of non-exhaustive possible forms of representation can be found in the figures.
    A further development is that at least one reference position is stored in the geodetic computing module. To prepare or plan a movement in the field, distinctive reference positions can be determined in advance and at least one can be stored in the geodetic computing module. For this purpose, the geodetic computing module can be connected, for example, to a data processing system. This development is advantageous because it enables a position of the long-range optical device to be determined with respect to an absolute coordinate system. This absolute position can be used in other navigation systems in order to be able to implement additional navigation services, for example route guidance to further distant people who cannot be reached by optical and / or acoustic means.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    Each show in a highly simplified, schematic representation:

    1 to 3 and 5, the long-range optical device is shown in a schematic detailed representation to illustrate the method steps. In one possible embodiment, this detailed illustration shows binocular binoculars.
    1 shows the objective-approach method in question, carried out with / from a long-range optical device 1, which device comprises observation optics 4, a distance measuring device 5 and an orientation determination device 7. When approaching the target at target position 3 (Pt), a situation may arise where the target will no longer be visible. The carrier of the long-range optical device 1 therefore needs a possibility of being able to determine the direction and distance to the target at its current position in order to be able to continue the approach to the target. At an intermediate position 12 (Pi), the carrier of the long-range optical device 1 therefore targets a reference position 34 (Pr), for example by observing the reference position 34 through the observation optics 4 and triggering the adaptation step. This reference position 34 stands out
    14/39
    N2016 / 25300-AT-00 from the fact that it is stationary and is in a position, or because of its dimensions, always along the way, or the vast majority, can be seen and is therefore sightable. Not conclusively, for example, this can be a widely visible terrain marker, a free-standing tree or
    Be a transmission tower.
    In the adaptation step, the distance 13 between the long-range optical device 1 and the reference position 34 is determined by means of the distance measuring device 5. Furthermore, a difference angle 14 between an absolute direction 9 and a reference direction 10 of the long-range optical device 1 is determined by means of the orientation determination device 7. The earth's magnetic field is preferably selected as the basis for determining the absolute direction 9, since this is available at any time and in a trouble-free manner, particularly in open terrain. In this case, the orientation determination device 7 is a compass, mostly an electronic compass.
    The reference position 34 characterizes a further feature, namely that the distance (reference distance 35) and the angle with respect to the absolute direction 9 (reference angle 36) to the target are known from this reference position 34. For example, these values can be determined in an upstream referencing step, as is described in a subsequent figure.
    Since the relative position (reference distance 35 and reference angle 36) from the reference position to the target position 3 is known, the geodetic computing module 15 can use trigonometry to determine the position from the determined position from the intermediate position 12 to the reference position 34 (difference distance 13 and difference angle 14) to the target at target position 3 (target distance 16 and target angle 17).
    The particular advantage of the subject method is that a wearer of the long-range optical device 1, who can carry out the objective target approach method, at any point along the path if the target has been lost in sight or is no longer visible, the direction at all times and can redetermine the distance to the target. This provision is in particular with
    15/39
    N2016 / 25300-AT-00 high accuracy possible, since reference is always made to a reference point.
    2 shows a possible application of the objective approximation method in question. A carrier of a long-range optical device 1 is located with the long-range optical device at a starting position 2. At this starting position 2 (Ps), a target at a target position 3 (Pt) is targeted by means of the far-optical device 1.
    In a target position determination step at the start position 2, the target at the target position 3 is sighted by means of the observation optics 4. A first distance 6 from the starting position 2 to the target position 3 is determined by means of a distance measuring device 5. This distance measuring device 5 is a contactless distance measuring device and is formed, for example, by a laser distance meter.
    In addition, the long-range optical device 1 has an orientation determination device 7, which determines a first angle 8 between an absolute direction 9 and a reference direction 10 of the long-range optical device 1 when aiming at the target. In one possible embodiment, the orientation determination device 7 is formed by a compass, preferably by an electronic compass, so that the absolute direction 9 is formed by the north direction.
    When the target position 3 is approached, the carrier of the long-range optical device 1 moves on a path 11 to an intermediate position 12 (Pi). Because of the spatial conditions, in particular due to the shape of the terrain, this path 11 will usually not run in a straight line, which can make orientation to the target difficult under certain circumstances or the target can be lost in sight.
    Therefore, according to a possible variant of the method according to the invention, an adaptation step is provided in which the starting position 2 is sighted at the intermediate position 12, which is spatially distant from the starting position 2, using the observation optics 4 and a difference 16/39 by means of the distance measuring device 5
    N2016 / 25300-AT-00 distance 13 from intermediate position 12 to start position 2 is determined. In addition, a difference angle 14 between the absolute direction 9 and the reference direction 10 of the long-range optical device is determined simultaneously by means of the orientation determination device 7. From the first distance 6 and the first angle 8, as well as the difference distance 13 and the difference angle 14, a new and current target distance 16 and a target angle 17 are determined by a geodetic computing module 15 using trigonometric calculation methods. The determined target distance 16 and the determined target angle 17 are shown correspondingly to the wearer of the long-range optical device 1 on a display means 18. On the basis of this data, the wearer of the long-range optical device 1 can adapt and continue his approach to the target 3.
    FIG. 3 shows a further possible alternative variant of the objective approximation method in question, which uses an explicit reference position 34 as the basis for the target navigation. This variant represents an extension of the variant shown in FIG. 1 and, as already described in FIG. 1, has the particular advantage that in exposed, difficult terrain, an exposed feature is used as the basis for the target navigation.
    Due to the topological conditions, it may be recognizable for the user of the long-range optical device that the starting position 2 will not be partially sightable along the approach to the target position 3. In this case, the reference position 34 is sighted in the target position determination step by means of the observation optics 4, and a reference distance 35 from the start position 2 to the reference position 34 is determined by means of the distance measuring device 5. A reference angle 36 between the absolute direction 9 and the reference direction 10 of the long-range optical device 1 is determined by means of the alignment determination device 7. In the adaptation step, the geodetic computing module 15 determines the target distance 16 and the target angle 17 from the reference distance 35 and the reference angle 36, as well as the difference distance 13 and the difference angle 14.
    If there is a situation on the path that the selected reference position disappears from the field of view, the referencing step can be carried out again

    N2016 / 25300-AT-00 to set a new reference position. The new reference position to be used in the future is sighted, and from the known distance and the known angle to the target (this will mostly be the target distance and the target angle of the current position), and from the determined difference values (this will mostly be the difference distance and the Difference angle), a new reference distance and a new reference angle are determined. This enables reliable navigation to a destination even over long distances.
    FIGS. 4 a) and b) show the objective approach method in question when the adaptation step is carried out iteratively along the path 11 to the target position 3. In FIG. 4 a, the starting position (start position 2 or reference position 34) is always sighted, in FIG. 4 b targeted to the last position.
    4a shows the situation in which reference is always made back to the starting position of path 11 along path 11. 4a, this is the starting position Ps 2. In the target position determination step, the first distance Di 6 and the first angle ai 8 to the target at the target position Pt 3 are determined from the starting position Ps 2.
    The carrier of the long-range optical device then moves on a path 11 in the direction of the target position 3. At a first intermediate position Pu 19, 12, an adaptation step already described is carried out and the first difference distance Du 13 and the first difference angle au 14 are determined. From the first distance Di 6 and the first angle ai 8 determined in the target position determination step, the first target distance Dti 16 and the first target angle ατι 17 are determined and displayed to the wearer of the long-range optical device on the display means.
    The carrier of the long-range optical device then moves on path 11 to the second intermediate position P12 20 and carries out the adaptation step again there, and ascertains a second difference distance D12 21 and a second difference angle ai2 22. From the first distance Di 6 and the first angle ai 8, and the second difference distance D12 21 and the second difference angle ai2 22, a second target distance Dt2 23 and a second target angle ατ2 24 are determined.

    The wearer of the long-range optical device continues on path 11 to the third intermediate position 25 and there carries out the adaptation step again. A detailed description of the individual processes is omitted, since these are the same as the steps in the adaptation step at the second intermediate position 20.
    In the adaptation step, a third difference distance Di3 and a third difference angle ai3 are determined and, as before, a third target distance Dt3 and a third target angle ατ3 are determined.
    If a reference position 34 is used as the basis for the target navigation instead of the starting position 2, the described case II is carried out in the adaptation step. The reference position is sighted and the geodetic computing module uses the reference distance or the reference angle to determine the target distance and the target angle. All other processes described remain the same.
    According to FIG. 4b, the first distance 6 and the first angle 8 to the target at the target position 3 are determined from a starting position 2 in the first target position determination step. The carrier of the long-range optical device then moves on a path 11 and carries out an adaptation step already described there. The first differential distance 13 and the first differential angle 14 are determined at a first intermediate position 19, 12, and the first target distance 16 and the first target angle 17 are determined from the first distance 6 and the first angle 8 determined in the target position determination step. The carrier of the long-range optical device then moves on path 11 to the second intermediate position 20 and carries out the adaptation step again there. However, the first intermediate position 19 is now targeted as the start position of the adaptation step and a second difference distance 21 and a second difference angle 22 are determined. A second target distance 23 and a second target angle 24 are determined from the target distance 16 as the first distance of the adaptation step and the target angle 17 as the first angle of the adaptation step and the second difference distance 21 and the second difference angle 22.

    N2016 / 25300 AT-00
    The wearer of the long-range optical device continues on path 11 to the third intermediate position 25 and there carries out this adaptation step again with the second intermediate position 20 as the starting position of the adaptation step. A description of the individual processes is omitted, since these are the same as the steps in the adaptation step at the second intermediate position 20, the indices having to be adapted to the third intermediate position.
    With the objective approximation method in question, it is now possible to reach the target after it has been sighted for the first time and a distance and an angle to the target has been achieved, by iteratively executing the adaptation step along a path, even if the path deviates significantly from the straight connection.
    1 to 4, the situation of the objective approach method on the plane has been described, that is to say if there are only slight differences in height between the start and target position, and in particular on the path in between. In particular, the start and finish as well as the path between them are largely in a horizontal plane. Under these conditions, a purely two-dimensional consideration of the distance and the angle is sufficient to be able to neglect the height components of the distance.
    In real terms, however, it is likely that there will be a height difference between a starting position and the target position, and in particular height differences (ascents and descents) will have to be overcome on the way in between. 5 now shows the situation in which there is a height difference 26 between the starting position 2 and the target position 3 and the intermediate position 12 is higher than the starting position 2 and lower than the target position 3. The path 11, which the wearer of the long-range optical device 1 will cover to the target position 3, can deviate significantly from a straight elevation. In particular, it is possible for a position to be overcome to reach an intermediate position 12 that is higher than the intermediate position.
    According to an advantageous further development, the long-range optical device 1 also has an inclination measuring device 27, which is connected to the computing module 15 and which
    20/39
    N2016 / 25300-AT-00 transmitted an inclination to the horizontal as a height angle to the computing module 15. As a result, the objective approximation method in question is expanded in such a way that a first height angle 28 is additionally determined in the target position determination step at the starting position 2 when the target position 3 is sighted. The carrier of the long-range optical device will then move along the path 11 to the first intermediate position 12 and carry out the adaptation step there. The starting position 2 is sighted and a difference in height angle 33 is determined. The geodetic computing module 15 determines the target height angle 30 from the determined first height angle 28 and the differential height angle 33.
    If there are several intermediate stations on the way between the start and the target position, the above description is similar to the one for the flat route, to switch to a route with several intermediate stations.
    The detail representation in FIG. 5 only shows the relevant components of the long-range optical device 1. For further details of the long-range optical device 1, reference is made to the description of the previous figures.
    When moving off-road, especially during a hunt, it may happen that a wearer of the long-range optical device 1 at the start position 2 can sight the target at the target position 3 well, but can only reach the target with difficulty due to spatial conditions. According to a further possible embodiment of the objective approach method in question, it is therefore possible for the distance-measuring device of the long-range optical device to transmit direction information 31 relating to the destination to a second long-range optical device 1 at a transfer position 32, as is shown schematically in FIG. 6 is shown. The distance measuring device of the long-range optical device is preferably designed as a laser distance measuring device, which emits a sequence of laser pulses and determines the distance to the target from a transit time determination.
    With these pulses or in pulse pauses it can be provided that the directional information is transmitted packed. Thus, the carrier of the first long-range optical device needs to sight the second far-optical device and trigger the transmission of the directional information.
    21/39
    N2016 / 25300 AT-00
    If the carrier of the first long-range optical device is at the start position 2 and has not yet carried out an adaptation step, the first distance 6 and the first angle 8 are transmitted as the direction information 31 as the second direction information 31. However, it is also possible that the carrier of the long-range optical device 1 has already moved along the path and is now at an intermediate position 12, from which the further path becomes difficult. The carrier of the first long-range optical device therefore carries out the adaptation step at the intermediate position 12 and the target distance 16 and the target angle 17 are transmitted to the second far-optical device as first direction information 31.
    Since the second long-range optical device is located at a different position than was used as the starting point for creating the directional information, the directional information about the destination at the target position 3 must be determined again. The difference distance and the difference angle between the first and the second long-range optical device are also determined during the transfer.
    The adaptation step is therefore carried out by the far-optical device 1 at the transfer position 32, in which the start position 2 or intermediate position 12 of the transmitting, far-optical device 1 is set as the start position of the adaptation step. However, it is also possible that the adaptation step is carried out by the far-optical device 1 at the start position 2 or at the intermediate position 12, the physical start position or the physical intermediate position of the far-optical device being defined as the start position of the adaptation step. This case corresponds to a forward calculation of the target distance or the target angle, since the target distance and the target angle had already been determined at the transfer position 32 before the directional information was transferred to the second long-range optical device 1.
    What is particularly advantageous about this embodiment is that it is possible to transmit directional information without additional communication means and in particular while avoiding data loss, so that a second long-range optical device at a transfer position can continue to approach the destination seamlessly, if this is not the case for the transmitting long-range optical device or is difficult to do.

It can be provided that the directional arrows represent the direction in which the long-range optical device is to be moved by filling or partially filling the arrow body. If all arrows are filled / empty, the center of the field of view is aligned with the target. The correct alignment could also be represented by an optical effect, for example in which all direction arrows 37 flash briefly. Alternatively, only one arrow could be provided, which is shown along the circumference of the display means 18, its position indicating the movement for aligning the long-range optical device. FIG. 7b shows a similar situation, only the elements of the reticle (specifically reticle 8) are used here to represent the alignment information. A filled / empty bar of the reticle 38, as before, indicates the direction in which the long-range optical device has to be moved in order to be aimed at the target. For example, the distance between the ends of the reticle 38 could be used to represent the distance. Or a length-adjustable bar or the like is also shown.
    7c uses scales to represent the alignment information. If only the middle scale division element is displayed intensely, the long-range optical device is aimed at the target. For example, a scale element could blink to represent the distance, or a portion of the scale parallel to the representation of the alignment information could be used as a distance bar
    7d shows a data terminal 39 which forms the display means 18, wherein the data terminal 39 can be a smartphone, for example. A directional arrow 41 and a distance 42 will be shown on a display 40. The

    N2016 / 25300 AT-00
    Data terminal 39 preferably also has a position determination module, so that one's own orientation can be determined and a deviation from the determined target angle can be represented. When correctly aligned, the data terminal points exactly in the direction of the target position.
    The display means 18 shown in FIG. 7 are not final examples of possible variants of how the target angle and the target distance can be displayed to the user of the long-range optical device. Further possible display variants, not shown, are explicitly included. A communication connection will exist between the data terminal 39 and the geodetic computing module, preferably a wireless connection such as Bluetooth, ZigBee or the like.
