    [0001] METHOD AND DEVICE TO CONVERT A 2D IMAGE TO A 3D IMAGE, AND
    [0003] FIELD OF THE PRESENT DISCLOSURE
    [0005] The present disclosure relates to the field of image processing technology, in particular to a method and a device for converting a two-dimensional (2D) image to a three-dimensional (3D) image, and to a 3D imaging system.
    [0007] BACKGROUND TO THIS DISCLOSURE
    [0009] When both eyes of a human being look at an object one way, the perception of the thickness of the objects seen and the depth or distance of space and the like can be subjective. This is known as stereoscopic vision. The main reason is that the images of the same object seen are not exactly identical in the retinas of both eyes, since the left eye sees more of the left side of the object from the left while the right eye sees more of the right side of the object. from the right; and after the image information from both eyes is processed through a primary visual center, a stereoscopic image of the object is generated.
    [0011] With the development of display technology and digital technology, imitating the stereoscopic vision of human eyes by using electronic products has become a research benchmark. In the prior art, users can view a 3D image only if a 3D camera device is employed. Most existing 3D camera devices work by mimicking the structure of human eyes, each of which comprises two cameras, where an image acquired by one of the cameras corresponds to an image of the human left eye, and an image acquired by the other camera corresponds to an image of the human right eye; then, the left eye image and the right eye image can be synthesized with an image processing means to form the 3D image.
    [0012] In the prior art, when the 3D camera device is used to acquire the image, two polarizers with polarization directions perpendicular to each other are generally arranged in front of a lens of each of the cameras, to obtain images corresponding to the left eye and the left eye. right eye. Since each camera acquires the image in only one polarization direction, this assumes that the resolution and definition of the entire image will be half of the actual image, thereby altering the 3D imaging effect.

    [0112] DESCRIPTION OF THE EMBODIMENTS
    [0114] In order to clarify the purposes, technical solutions and advantages of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and thoroughly described with reference to the accompanying drawings of embodiments of the present disclosure. Apparently, the described embodiments are a part of the present disclosure and not all of the embodiments thereof. All other embodiments obtained by those skilled in the art from the embodiments described in the present disclosure, without contribution to the creative process, are within the scope of protection of the present divulgation.
    [0116] According to the method for converting a 2D image to a 3D image, the binocular parallax images, that is, a left eye image and a right eye image, are created to achieve stereoscopic vision by transforming the perspective of the 2D image; adjusts the distance between the left eye image and the right eye image to create a convergence angle; and by using the binocular parallax images in combination with the convergence angle, a 3D image can be formed.
    [0118] An embodiment of the present disclosure provides a method of converting a 2D image to a 3D image, as shown in Fig. 1, comprising the following steps:
    [0120] S11, acquire a 2D image to be processed;
    [0122] The 2D image to be processed, acquired by a device to convert a 2D image into a 3D image, can be a 2D photo, it can also be an image frame of a video sequence, and it can also be obtained by acquiring videos in real time and extracting each image frame of the videos, as long as it can be ensured that the device to convert a 2D image into a 3D image can acquire the 2D image to be processed.
    [0124] S12, carry out a perspective transformation on the 2D image to be processed to obtain a left eye image and a right eye image, respectively.
    [0126] Perspective transformation refers to mapping the 2D image to be processed according to a preset rule. The device for converting a 2D image to a 3D image maps the 2D image to be processed according to the preset rule, that is, the left eye image and the right eye image are formed by image processing according to the transformation of the perspective based on the 2D image to be processed. The predefined rule is used to represent a form of perspective transformation, eg. ex. a transformed image will have a near end that looks large and a far end that looks looks small, or a perspective image is calculated using a formula.
    [0128] 513, adjusting the distance between the left eye image and the right eye image according to the result of the perspective transformation;
    [0130] The device for converting a 2D image to a 3D image adjusts the distance between the left eye image and the right eye image formed after the perspective transformation, to create a convergence angle.
    [0132] The inventors have discovered, through a large number of experiments, that the corresponding convergence angle changes as the distance between the images changes. For example, as shown in Fig. 2, the relationship between the convergence angle and the distance between the left eye image and the right eye image is described. As shown in Fig. 2a), when the convergence angle is a1, the distance between the left eye and the right eye is relatively small; and as shown in Fig. 2b), when the convergence angle is a2, the distance between the left eye and the right eye is relatively large. In other words, the angle of convergence will change accordingly with the change in the distance between the left eye and the right eye. Therefore, in the present disclosure the angle of convergence is created by adjusting the distance between the left eye and the right eye.
    [0134] 514, synthesize the left eye image and the right eye image after adjusting the distance;
    [0136] The device to convert a 2D image into a 3D image synthesizes the left eye image and the right eye image after adjustment, that is, making use of the binocular parallax created through the transformation of the image and the convergence angle, the left eye image and the right eye image are synthesized after adjusting the distance and then sent to an image display medium, for subsequent viewing of the 3D image. Subsequent display of the image involves adjusting the polarization directions of the left eye image and the right eye image to make the polarization directions of the two images perpendicular to each other, so that the user can view a 3D image by wearing 3D glasses during use. Other ways can also be used to adjust the polarization directions, as long as the polarization directions of the two images, which are viewed respectively through both eyes of a person, are perpendicular to each other.
    [0138] In accordance with the embodiment of the present disclosure, binocular parallax images are created to achieve stereoscopic vision by performing perspective transformation on the 2D image to be processed. Additionally, the distance between the left eye image and the right eye image after the perspective transformation is adjusted to form a binocular parallax and create the convergence angle, so that the images observed by naked eyes are at different depths, thus being able to see different stereoscopic effects. In other words, the image transformation is carried out on the 2D image without affecting the resolution and definition of the image, so that the quality of the 3D image is the same as that of the original 2D image and the 3D imaging effect is not affected.

The amount of processed data is reduced by sequentially carrying out linear scaling on the respective lines, so that the 2D image conversion can be carried out in real time.
