    NOTE ART
    [0001] The present invention relates to a geodesy instrument, through which it is possible to facilitate the vision of a target to be measured.
    [0002] Conventionally, in the case where a geodesy operation is performed by a geodesy instrument, which does not use a reflector such as a reflection prism or the like, the pointing of a point to be measured is carried out by means of a telescope.
    Telescope aiming is typically performed by various methods. For example, the following and similar methods are known: a method of controlling a pilot unit by means of an interface, such as a button or spider on a screen of a remote operations control unit, or a method in where a camera image taken by the geodesy tool is shown on a remote operation control unit and a point to be displayed is specified on the image.
    However, in the case where the pointing is performed by means of a button or a slider on the screen, an operator cannot perform the pointing by sensory operation, since the view will be on controlling an interface on the screen. Moreover, in the event that a point to aim is to select from the screen, there are restrictions on the field of view or on a display that resolves the magnification power of the camera. Furthermore, in case it is difficult to locate the screen such as in case the illumination is not sufficient in the measurement environment or the dynamic range is wide or similarly due to the fact that the background illumination is high, the work efficiency decreased.
    SUMMARY OF THE INVENTION
    [0005] The object of the present invention is to provide a geodesy instrument, through which it is possible to easily guide towards the measuring point and with which the working efficiency is improved.
    [0006] In order to achieve the objective described above, a geodesy instrument according to the present invention comprises a main body of the geodesy instrument and a remote operations control unit connectable to and disconnectable from the main body and capable of communicating with the main body, in which the main body comprises a telescope unit for displaying a measurement point, a laser pointer irradiation unit for radiating a laser pointer beam running parallel to or on the same axis as an optical axis of the telescope unit, a rotation guide unit to rotate the telescope unit in a predetermined direction, a horizontal angle meter to measure the value of a horizontal rotation angle of the telescope unit, a meter d vertical angle to measure the value of a vertical rotation angle of the telescope unit, and a control unit of the main body to control turn the rotation guide unit in order to direct the telescope unit in a predetermined direction, wherein the remote operation control unit has an operation button, a directional angle sensor to measure a directional angle of the unit remote operation controller and a vertical sensor for measuring a vertical angle of the remote operation controller, wherein the measurement values of the horizontal and vertical rotation angles are transmitted to the remote operation controller by pressing the operation button in the condition in which the remote operation control unit is removed, in which the operation control unit calculates a difference between the directional angle detected by the directional angle sensor before a movement of the remote operation control unit and the angle directional after handling and a difference between the vertical angle identified by the vertical sensor before handling ee of the vertical angle after handling, in which alternatively one of the remote operation control unit and the main body control unit calculates, after handling, the measurement values of the horizontal rotation angle and the angle of vertical rotation based on the differences and the main body control unit rotates the telescope unit to become the measurement values of the horizontal rotation angle and the vertical rotation angle calculated after handling. As a result, it is possible to easily guide to a position distant from the main body of the geodesy instrument, the pointing direction of the telescope unit towards a measurement point being able to visually confirm an irradiation position of the laser pointer beam, and this contributes to improve work efficiency.
    [0007] Preferably, but not limitedly, in the geodesy device according to the present invention, the remote operations control unit calculates the difference between the directional angle before the movement and the directional angle after the movement and the difference between the vertical angle before moving and vertical angle after moving continuously if the operating button is pressed, and transmits a rotation instruction to the main body controller continuously. As a result, it is possible to carry out the movement of the main body of the geodesy instrument to follow the movement of the remote operation control unit, and this makes it possible to guide the beam of the laser pointer towards the measurement point in a simpler manner.
    [0008] Preferably, but not limitedly, in the geodesy instrument according to the present invention, the remote operations control unit identifies the directional angle after the movement and the vertical angle after the movement at the moment in which the operating button is released , and calculates a difference between the directional angle at the time the operation button is pressed and the directional angle at the time the operation button is released and the difference between the vertical angle at the time the operation button is pressed and the vertical angle at the moment the operating button is released, and transmits a rotation instruction to the main body controller. As a result, there is no need to calculate the difference by finding the directional angle and the vertical angle after handling all the times, and this makes it possible to reduce the processing load of the remote operation control unit.
    [0009] Preferably, but not limitedly, the geodesy instrument according to the present invention further comprises an electro-optical distance meter, in which the optical axis of the electro-optical distance meter is on the same axis or runs parallel to the beam of the laser pointer. As a result, when a distance measurement of the measurement point is to be made, it is simply necessary to guide the beam of the laser pointer to a measurement point, and this contributes to the improvement of the working efficiency when the distance measurement is performed.

    DETAILED DESCRIPTION OF THE INVENTION
    The description will be provided below in embodiments of the present invention referring to the accompanying drawings.
    [0013] First of all, with reference to fig. 1 to fig. 3, a description of a geodesy tool according to a first embodiment of the present invention will be provided.
    A geodesy tool 1 has a tripod 2, and a leveling unit 3 which is installed on the top portion of the tripod 2.
    On the leveling unit 3, a pivot base 5 is rotatably mounted through a horizontal pivot shaft 4, and the leveling unit 3 has a leveling mechanism (not shown) to perform leveling in a vertical direction and an inclination sensor 6 (which will be described later). Within the leveling unit 3, a rotation guide unit 7 is incorporated so that the rotation base 6 is rotated around the horizontal rotation shaft 4 as a center by the horizontal rotation guide unit 7.
    A frame box 8 is installed in a vertical direction on the rotation base 6, and the telescope unit 11 is rotatably mounted on the frame box 8 through a rotation shaft 9, which possesses a horizontal axis.
    The telescope unit 11 has an observation telescope 12. The observation telescope 12 has an angle of view of about 5 ° and points to a measuring point. A pointing point of the aiming telescope 12 is shown through a reticle (not shown) provided on the aiming telescope 12.
    A vertical rotation guide unit 13 is incorporated in the frame box 8, and the telescope unit 11 is rotated in the vertical direction around the vertical rotation shaft 9 as a center by means of the guide unit vertical rotation 13.
    [0019] The horizontal rotation guide unit 7 and the vertical rotation guide unit 13 together form a rotation guide unit. Through a cooperative operation of the vertical rotation guide unit 13 and the horizontal rotation guide unit 7, the rotation guide unit can direct the telescope unit 11 in a desired direction.
    On an upper surface of the telescope unit 11, an electro-optical distance meter (EDM) 14 is installed, and an irradiation unit of a laser pointer 15 is incorporated in the electro-optical distance meter 14.
    The electro-optical distance meter 14 can perform a non-prismatic distance measurement, and the irradiation unit of the laser pointer 15 is designed to irradiate a laser beam (a laser pointer beam) 16 of visible light. An optical axis of the beam of the laser pointer 16 coincides with the optical distance measuring axis of the electro-optical distance measurer 14.
    Furthermore, the telescope unit 11 is integrated with the electro-optical distance meter 14. The optical axis of the electro-optical distance meter 14, i.e. the optical axis of the beam of the laser pointer 16 runs in parallel to the optical axis of the telescope unit 11, and a distance between the optical axes of the beam of the laser pointer 16 and of the telescope unit 11 is already known. It should be noted that this is installed in such a way that the optical axis of the telescope unit 11 is the same axis as the optical axis of the beam of the laser pointer 16, and that the optical axis of the telescope unit 11 is the optical axis of the beam of the laser pointer 16 run in parallel to an optical distance measuring axis of the electro-optical distance measurer 14. Also, the electro-optical distance measurer 14 can be installed on the telescope unit 11 through a connection (not shown), or the direction of the optical axis of the electro-optical distance meter 14 may be adjustable via the connection. In this case, a commercial grade electro-optical distance meter 14 can be used.
    [0023] A horizontal angle measurer 17 is installed on the horizontal rotation shaft 4, and is installed in such a way that the horizontal angle measurer 17 can identify a rotation angle of the horizontal rotation shaft 4, namely the horizontal rotation angle of the rotation base 5. In addition, a vertical angle measurer 18 is installed on the vertical rotation shaft 9, and the vertical angle measurer 18 can detect a rotation angle of the vertical rotation shaft 9, and therefore an angle of vertical rotation of the telescope unit 11.
    Furthermore, a control unit of the main body is installed inside the rotation base 5. It is noted that if there is room for the main body control unit, the main body control unit 19 can be installed on other sites such as on the telescope unit 11 and so on. The main body control unit 19 can be designed to control the horizontal rotation guide unit 7 and the vertical rotation guide unit 13, and to control the distance measurement through the electro-optical distance meter 14 , to control the irradiation unit of the laser pointer 15, to measure the horizontal and vertical angle based on the detection results of the horizontal angle meter 17 and the vertical angle meter 18, and to perform data communications to and from a remote operations control unit 21 as will be described below. It should be noted that with the exception of the remote operation control unit 21, the leveling unit 3, the rotation base 5, the frame box 8, the telescope unit 11 etc., all form a main body together. of the geodesy tool.
    It is configured such that the remote operations control unit 21 can be connected to or removed from the leveling unit 3 through a connection 22 (see FIG. 2).
    [0026] As shown in Fig. 3, the remote operations control unit 21 is designed as a portable device (of the handheld type) such as a smartphone, tablet or similar, if the remote operations control unit 21 can be operated through one hand in a state where the other hand holds the remote operations control unit 21.
    The remote operation control unit 21 has a display unit 23 and an operating unit (the display unit 23 acts as a touch sensitive panel and also serves as an operating unit), and a communication unit (which will be described below) and the like in order to perform data communications to and from the main body control unit 19. Furthermore, the remote operations control unit 21 is provided with a vertical sensor 24 and a directional angle 25 to measure the posture and direction of the remote operation controller 21.
    As shown in Fig. 2, it can be installed such that an optical deflection unit 26 is installed on the telescope unit 11 and the optical axis of the telescope unit 11 can be deflected by the unit of optical deflection 26 such that a part of the light of the electro-optical distance measurer 14 is reflected back onto the telescope unit 11 and such that an aiming point of the telescope unit 11, the measuring point of the electro-optical distance measurer 14 and the irradiation point of the irradiation unit of the laser pointer 15 coincide with each other.
    [0029] Since the telescope unit 11 is rotated horizontally and vertically by an operation from the remote operations control unit 21, the operation enables the geodesy tool 1 to perform operations as required such as for example operations to determine the direction of observation, an operation to determine measurement points, or an operation to make measurements or the like. If the remote operations control unit 21 is installed on the geodesy instrument 1, the geodesy instrument 1 is in a condition in which the telescope unit 11 is directly operated through the remote operations control unit 21. In the condition in which where the remote operations control unit is disconnected, the geodesy instrument 1 is in a condition where the telescope unit 11 is remotely controlled through the remote operations control unit 21.
    Provided that a connectable and disconnectable type connector (not shown) is provided on each remote operation control unit 21 and connection 22, and the remote operations control unit 21 is installed on connection 22 , the configuration is such that the remote operations control unit 21 is directly and electrically connected to the main body control unit 19 through the connection of a connector.
    With reference to FIGS. 4 and FIG. 5, the following description will be provided on the main body control unit 19 and on the remote operations control unit 21.
    [0032] First of all, with reference to Fig. 4, the description of the control unit of the main body 19 will be provided.
    [0033] The control unit of the main body 19 primarily comprises a first arithmetic control unit 27, a first storage unit 28, the horizontal angle measurer 17, the vertical angle measurer 18, the inclination sensor 6 , the operating unit 29, a first communications unit 31, the electro-optical distance meter 14, the horizontal rotation guide unit 7, the vertical rotation guide unit 13, the display unit 23, a first power supply unit 32, and so on.
    [0034] The detection signals from the horizontal angle meter 17, the vertical angle meter 18 and the inclination sensor 6 are fed into the first arithmetic control unit 27. At the first communication unit 31, a communication is controlled by the first arithmetic control unit 27, and a control command is sent by the first communication unit 31, and the data received by the first communication unit 31 are input to the first arithmetic control unit 27.
    The first arithmetic control unit 27 controls the electro-optical distance meter 14, and the result of a measurement of the electro-optical distance meter 14 is input to the first arithmetic control unit 27. arithmetic control 27 controls the horizontal rotation guide unit 7 and the first vertical rotation guide unit 13, and makes the telescope unit 11 and the electro-optical distance meter 14 rotating in one direction as required.
    [0036] The measurement result of the horizontal angle measurer 17 and the vertical angle measurer 18 are input to a first arithmetic control unit 27. Based on the detection results of the horizontal angle measurer 17 and from vertical angle meter 18, the angle of rotation in the horizontal direction and the angle of rotation in the vertical direction of the optical deflection unit 26, the electro-optical distance meter 14 and the radiation unit of the pointer are measured laser 15.
    The measurement result of the tilt sensor 6 is input to the first arithmetic control unit 27, and a smoothing operation of the leveling unit 3 is controlled, and based on the measurement results of the tilt sensor 6 and of the vertical angle measurer 18, the vertical angle of the telescope unit 11 is measured.
    An operating unit and a display unit as provided on the remote operation control unit 21, as written below, duplicate the display unit 23 and the operating unit 29.
    [0039] In the first storage unit 28, different types of programs are stored. These programs include: a control program necessary to control the electro-optical distance meter 14, the first communications unit 21, the horizontal rotation guide unit 7 and the vertical rotation guide unit 13, a control program angle measurement to specify a tilt angle, horizontal rotation angle, vertical rotation angle, etc. based on the measurement results of the horizontal angle meter 17, the vertical angle meter 18 and the tilt sensor 6, and a communications control program for controlling the communication via the first communications unit 31, etc.
    Furthermore, the measurement data and the like, such as distance measurement results, angle measurement results, etc. by the electro-optical distance meter 14 are stored by the first storage unit 28.
    [0041] The first power supply unit 32 is a rechargeable battery such as a lithium ion battery or the like, and the first power supply unit 32 supplies electrical power as needed to power the first arithmetic control unit 27, the first communication unit 31, the horizontal rotation guide unit 7, and the vertical rotation guide unit 13, and so on.
    With reference to FIG. 5, the description given below will be provided regarding the remote operations control unit 21.
    [0043] The remote operations control unit 21 primarily comprises a display unit 23, an operating unit 29, a second arithmetic control unit 33, a second storage unit 34, a vertical sensor 24, an angle sensor directional unit 25, a second communication unit 25, a second power supply unit 36, and so on.
    The measurement signals from the vertical sensor 24 and the directional angle sensor 25 are input to a second arithmetic control unit 33, and the second arithmetic control unit 33 calculates the posture of the remote operations control unit 21 based on signals coming from the vertical sensor 24 and the directional angle sensor 25.
    The second communication unit 35 receives the data transmitted by the control unit of the main body 19 and introduces the data into the second arithmetic control unit 33. Furthermore, the second communication unit 35 transmits information about a posture and the like of the remote operations control unit 21 as calculated by the second arithmetic control unit 33 and the like to the main body control unit 19.
    [0046] It is thus obtained that the data transmitted by the control unit of the main body 19, for example, or the information and the like thus calculated by the second arithmetic control unit 33 or the like are displayed on the display unit 23.
    Furthermore, the display unit 23 is designed to perform each operation as desired through the display unit 23 as a touch sensitive panel, or the functions of the operating unit 29 can be concentrated on the display unit 23. The display unit 23 has an operating button 30 for remotely controlling the telescope unit 11 and for carrying out beam guidance of the laser pointer 16.
    [0048] In the second storage unit 34, various types of programs and the like are stored. These programs include: a communications control program to control communications through the second communication unit 35, a program to perform displays on the display unit 23, and to perform the functions of the display unit 23 as an operating unit, a program for calculating information relating to the posture of the remote operation control unit 21, such as direction and inclination, etc. remote operations control unit 21 based on signals from vertical sensor 24 and directional angle sensor 25, a program for calculating the amount of movement of the telescope unit 11 based on the information and other programs. Furthermore, in the second storage unit 34, the distance and angle measurement data as determined by the geodesy instrument 1 are stored.
    The second power supply unit 36 is a rechargeable battery such as a lithium ion battery or the like, and the necessary electrical power is supplied to the second arithmetic control unit 33, to the second communication unit 35, to the display unit 23, etc.
    [0050] When the operating button 30 of the display unit 23 is pressed, i.e. at the moment when the operating button 30 is pressed through the vertical sensor 24, a vertical angle θ of the designated direction 37 of the control unit is measured remote operations before handling. Furthermore, when the operating button 30 is pressed by the directional angle sensor 25, the directional angle Φ of the designated direction 37 of the remote operations control unit 21 is detected before the movement.
    Furthermore, when the operating button 30 is pressed, a lowering signal is transmitted to the geodesy instrument 1 through the second communications unit 35 and the lowering signal is thus received through the first communications unit 31. A horizontal angle H of the telescope unit 11 is detected through the horizontal angle measurer 17 at the moment the operating button 30 is pressed, and a vertical angle V of the telescope unit 11 is detected by the vertical angle measurer 18 at the moment wherein the operating button 30 is pressed. This means that a measurement value of the angle H, V of the telescope unit 11 is measured, and the result is transmitted to the remote operation control unit 21.
    [0052] It is pointed out that after the operating button 30 is pressed, i.e., after handling, a directional angle and a vertical angle Φ ', θ' of the remote operation control unit 21 are measured continuously as long as the operating button 30 remains pressed. The second arithmetic control unit 33 calculates a difference Φ'- Φ, θ '- θ continuously through a directional angle and a vertical angle Φ', θ 'as identified by the movement and a directional angle and a vertical angle Φ, θ as identified before handling.
    [0053] Based on the sensitivity as predetermined or the sensitivity as set by the operator, the second arithmetic control unit 33 corrects the calculated difference Φ, θ '- θ with respect to the amount of angle deviation ΔH, ΔV of the telescope unit 11, and a rotation instruction is transmitted to the main body control unit 19 continuously such that the angle measurement value of the telescope unit is H + ΔH, V + ΔV.
    Based on the rotation instructions from the remote operation control unit 21, the main body control unit 19 drives the horizontal rotation control unit 7 and the vertical rotation control unit 13.
    [0055] In this way it is realized that the processing described above is continuously carried out as long as the operating button 30 is not released. Thus, when the remote operation controller 21 is moved while the operator presses the operation button 30, the telescope unit 11 is rotated in a horizontal direction through the following movement of the remote operation controller 21.
    [0056] Therefore, as shown in Fig. 6, the operator is able to guide the beam of the laser pointer 16 towards the measurement point 38 in a separate position with respect to the telescope unit 11.
    [0057] Hereinafter, referring to the flow diagram shown in Fig. 7, a description is given below in case the telescope unit 11 is remotely operated by the remote operations control unit 21 and the measurement is performed guiding the laser pointer 16 towards the measurement point 38. It is noted that in the description given below, an explanation is given in case the display unit 23 is used as an operating unit 29.
    [0058] (Step 1) First of all, when a beam irradiation instruction of the laser pointer 16 is input into the display unit 23 of the remote operation control unit 21, the instruction to radiate is input into the to the control unit of the main body 19. The radiation unit of the laser pointer 15 is driven, and the beam of the laser pointer 16 is irradiated.
    [0059] At this point, the measurement values of the angle H, V of the telescope unit 11 are identified and updated at all times based on the detection results of the inclination sensor 6, the horizontal angle measurer 17, and vertical angle gauge 18.
    [0060] (Step 2) The irradiation by means of the laser pointer starts, subsequently by pressing the operating button 30 of the display unit 23, the guiding process of the laser pointer 16 is started.
    [0061] (Step 3) When the operating button 30 is pressed, the measurement values of the angle H, V of the telescope unit 11, at the moment the operating button 30 is pressed, are transmitted to the control unit remote operations 21. Furthermore, based on the detection results of the vertical sensor 24 and the directional angle sensor 25, the directional angle and the vertical angle Φ, θ of the designated direction 37 of the remote operation controller 21 are identified at the time the operating button 30 is pressed.
    (Step 4) At the moment the operation button 30 is pressed, the designated direction 37 of the remote operation control unit 21 is moved in the measurement direction.
    [0063] (Step 5) At the moment the operating button 30 is pressed, by moving the remote operation control unit 21, the directional angle and the vertical angle Φ ', θ' after the movement are continuously detected.
    [0064] (Step 6) When the directional angle and the vertical angle Φ ', θ' after the movement are identified, the second arithmetic control unit 33 calculates a difference Φ '- Φ, θ' - θ between the directional angle, the vertical angle Φ, θ before the movement and the directional angle and the vertical angle Φ ', θ' after the movement.
    [0065] (Step 7) The second arithmetic control unit 33 corrects the calculated difference Φ '- Φ, θ' - θ for an amount of angle deviation ΔH, ΔV of the telescope unit 11 based on the predetermined sensitivity, and the rotation instruction is continuously transmitted to the control unit of the main body 19 so that the value of the measuring angle of the telescope unit 11 is H + ΔH, V + ΔV.
    [0066] In this case, the sensitivity for correcting the difference Φ '- Φ, θ' - θ with respect to the angle deviation amount ΔH, ΔV can be configured such that the difference Φ '- Φ, θ' - θ and the angle offset amount ΔH, ΔV will be equal to each other or such that the difference Φ '- Φ, θ' - θ is approximately 1/10 of the angle offset amount ΔH, ΔV.
    [0067] (Step 8) The procedure from step 4 to step 7 as described above is repeated continuously as long as the operating button 30 is released. This means, in the condition that the operation button 30 is pressed, that the telescope unit 11 is rotated following the movement of the designated direction 37 of the remote operation control unit 21.
    [0068] (Step 9) After the operating button 30 is released, it is judged whether the irradiation position of the beam of the laser pointer 16 coincides with the measurement point 38. In the case where the irradiation position of the pointer beam laser 16 does not coincide with the measurement point 38, the procedure is carried out again starting from step 2 up to step 8.
    [0069] (Step 10) In the event that the irradiation position of the beam of the laser pointer 16 coincides with the measurement point 38, by introducing an instruction for distance measurement as input, the laser pointer beam guiding procedure 16 is completed and a non-prismatic distance measurement to the measurement point 38 is performed by the electro-optical distance meter 14.
    [0070] (Step 11) When the non-prismatic distance measurement to the measurement point 38 is completed, the angle measurement value at the time of the non-prismatic distance measurement is shown on the display unit 23 together with the value distance measurement.
    [0071] (Step 12) Finally, when a shutdown instruction for the beam of laser pointer 16 is input from the display unit 23, the shutdown instruction is input to the body control unit 19, and the beam of the laser pointer 16 is turned off and the measurement of the measurement spot 38 is completed.
    As described above, in the first embodiment of the present invention, by pressing the operating button 30 of the display unit 23, the directional angle and the vertical angle Φ, θ of the remote operation control unit 21 are detected at the present moment. The difference Φ '- Φ, θ' - θ, when the designated direction 37 of the remote operation controller 21 is moved in an arbitrary direction, is corrected with the amount of angle deviation and added to the measurement value of the angle H, V in real time. By driving the horizontal rotation guide unit 7 and the vertical rotation guide unit 13, the movement of the telescope unit 11 is activated to continuously follow the movement of the remote operation control unit 21 as long as the operation button 30 remains pressed.
    Thus, using the remote operation control unit 21, the operator can guide the pointing direction of the telescope unit 11 towards the measurement point 38 in a gentle manner, while visually confirming the irradiation position of the beam of the laser pointer 16. As a result, even within the limit of the field of view of the aiming telescope 12 or a surface of a screen or the like, or in the case where it is difficult to locate the measuring point 38 due to insufficient illumination or due to the dynamic range being wide or similarly due to the background illumination being high, the beam of the laser pointer 16 can be guided easily to the measurement point 38, and the working efficiency can be improved .
    [0074] Due to the fact that the optical axis of the laser pointer beam coincides with the optical axis of the electro-optical distance measurer 14, and it is possible to control the rotation of the telescope unit 11 by a position separation through the remote operation control unit 21, the operator is capable of simply guiding the beam of the laser pointer 16 in the vicinity of the measurement point 38. Therefore, even in the case where the measurement point 38 and the position of the telescope units 11 are distant from each other, the beam of the laser pointer 16 can be guided towards the measurement point 38 in a simple and reliable manner.
    [0075] It would be sufficient for the operating button 30 of the display unit 23 to be pressed, and under these conditions the designated direction 37 of the remote operation control unit 21 is moved. As a result, there is no need to have a special operation to guide the beam of the laser pointer 16, and this makes it possible to reduce the load on the operator.
    [0076] Furthermore, due to the fact that the optical axis of the electro-optical distance measurer 14 lies on the same axis as the laser pointer 16, in case the distance measurement is performed relative to the measuring point 38, it would be sufficient guiding the beam of the laser pointer 16 towards a measurement point 38. This makes it possible to improve the working efficiency in distance measurement.
    [0077] In the first embodiment, the calculation of the difference Φ '- Φ, θ' - θ is corrected for the amount of the angle deviation ΔH, ΔV based on the sensitivity as reset or on the sensitivity as input from the 'operator.
    However, it can be configured in such a way that the non-prismatic distance measurement is performed by the electro-optical distance meter in parallel with the directional angle and vertical angle detection verticale ', θ' after the movement, and the sensitivity can be automatically adjusted based on the distance measurement result. Since the sensitivity can be automatically adjusted, the beam of the laser pointer 16 can be guided more easily.
    Furthermore, as illustrated in fig.8, performing the angle measurement by means of the horizontal angle measurer 17 and the vertical angle measurer 18, and performing the distance measurement through the electro-optical distance measurer 14 , while guiding the beam of the laser pointer 16, a three-dimensional point of a target to be measured 39 can be tracked without contact.
    [0080] In the first embodiment, the remote operations control unit 21 calculates the difference Φ '- Φ, θ' - θ and converts the difference Φ '- Φ, θ' - θ to the amount of deviation d ' angle ΔH, ΔV, and transmits the rotation instruction to the control unit of the main body 19 so that the angle measurement value of the telescope unit 11 is H + ΔH, V + ΔV. In any case, it can also be configured in such a way that the remote operation control unit 21 transmits the difference Φ '- Φ, θ' - θ to the main body control unit 19, and furthermore the control unit of the main body 19 determines the amount of angle offset ΔH, ΔV and can rotate the telescope unit 11 such that the angle measurement value is H + ΔH, V + ΔV.
    [0081] Hereinafter, with reference to the flow diagram shown in Fig. 9, a description of a measurement process according to a second embodiment will be provided in which the beam of the laser pointer 16 is guided towards a measurement point 38 for taking a measurement. It is noted that the configuration of the geodesy tool 1 in the second embodiment is the same as that of the first embodiment, and the same components as shown in fig. 1 to fig. 3 are referred to by the same symbol, and the detailed description is not shown here.
    [0082] (Step 21) First, when an instruction for irradiating a beam of the laser pointer 16 is introduced from a display unit 24 of a remote operation control unit 21, the instruction for The irradiation is input to a control unit of the main body 19. An irradiation unit of the laser pointer 15 is driven and the beam of the laser pointer 16 is irradiated.
    [0083] (Step 22) The irradiation by the beam of the laser pointer 16 is started, and then by pressing the operating button 30 of the display unit 23, the process of guiding the beam of the laser pointer 16 is started .
    [0084] (Step 23) When the operation button 30 is pressed, the measurement value of the angle H, V of the telescope unit 11, at the moment the operation button 30 is pressed, are transmitted to the control unit remote operations 21. In addition, based on the detection results by the vertical sensor 24 and the directional angle sensor 25, the directional angle and the vertical angle Φ, θ of a designated direction 37 of the operations control unit remote 21 are detected at the moment in which the operating button 30 is pressed.
    [0085] (Step 24) In the condition that the operation button 30 is pressed, the designated direction 37 of the remote operation control unit is moved to the measurement direction.
    [0086] (Step 25) When the designated direction 37 is shifted to the measurement direction, it is then judged whether the operating button 30 has been released or not.
    [0087] (Step 26) If it is judged that the operating button has been released, the directional angle and the vertical angle Φ ', θ' after the movement are detected by the vertical sensor 24 and the directional angle sensor 25.
    [0088] (Step 27) When the directional angle and the vertical angle Φ ', θ' after the movement (at the moment the operations button has been released) are identified, the second arithmetic control unit 33 calculates the difference Φ '- Φ, θ' - θ between the directional angle and the vertical angle Φ, θ before the movement and the directional angle and the vertical angle Φ ', θ' after the movement.
    [0089] (Step 28) Based on the predetermined sensitivity, the second arithmetic control unit 33 corrects the calculated difference Φ '- Φ, θ' - θ with the amount of angle shift ΔH, ΔV of the telescope unit 11 and the rotation instruction is transmitted to the control unit of the main body 19 such that the measured angle value of the telescope unit 11 is H + ΔH, V + ΔV. This means that the telescope unit 11 is rotated for a certain amount of movement while the operating button 30 remains depressed.
    [0090] (Step 29) After the telescope unit 11 is rotated, it is judged whether the irradiation position of the beam of the laser pointer 16 coincides with the measurement point 38 or not, and the procedure of steps 22 to 28 is repeated again.
    [0091] (Step 30) In the event that the irradiation position of the laser pointer beam 16 coincides with the measurement point 38, through the input of an instruction for distance measurement, the driving of the beam of the laser pointer 16 is completed and the electro-optical distance meter 14 performs a non-prismatic distance measurement towards the measuring point 38.
    [0092] (Step 31) When the non-prismatic distance measurement to the measurement point 38 is completed, the angle measurement value at the time of the non-prismatic distance measurement is displayed on the display unit 23 together with the value distance measurement.
    [0093] (Step 32) Finally, when the shutdown instruction for the beam of the laser pointer 16 is input from the display unit 23, the shutdown instruction is input into the control unit of the main body 19, and the beam of the laser pointer 16 is turned off and the measurement of the measurement point 38 is completed.
    Furthermore, in the second embodiment, using the remote operation control unit 21, the operator can guide the pointing direction of the telescope unit 11 towards the measuring point 38 according to its direction while continuing to look the irradiation position of the beam of the laser pointer 16. Consequently, it is possible to easily guide the beam of the laser pointer 16 towards the measurement point 38, and this helps to improve the efficiency of the work.
    [0095] Furthermore, in the second embodiment, the directional angle and the vertical angle Φ ', θ' can only be detected after the moment the operating button 30 has been released, and the difference Φ '- Φ, θ '- θ can be calculated, so that there is no need to locate the directional angle and the vertical angle Φ', θ 'constantly. This makes it possible to reduce the processing load to be applied to the remote operations controller 21.
    [0096] It should be noted that in both the first and second embodiments, the electro-optical distance meter 14 is integrated with the irradiation unit of the laser pointer 15, while only the irradiation unit of the laser pointer 15 can be used on telescope unit 11.
    In case a distance measurement is not required while the angle measurement value is required, only the irradiation unit of the laser pointer 15 can be provided on the telescope unit 11.
    [0098] Furthermore, in the first embodiment and the second embodiment, a portable type terminal is used, such as a smartphone or similar, in which the operating unit 29 is integrated with the display unit 23, while not it needs to be said that a general type portable wireless terminal can be used in case the display unit 23 and the operating unit 29 are supplied separately.
