The present invention provides a method and system for generating parallax images based on binocular stereo vision matching. The present application generates a binary image by using a pair of speckle images, and generates a parallax image according to the binary images. On the one hand, the information contained in the speckle images is relatively The physical map is simple and the influencing factors are small, but it can well reflect the surface properties of the object. Therefore, the disparity map calculated by extracting speckle information can effectively reduce the matching compared with the traditional binocular stereo vision methods (BM, SGBM, etc.). calculation amount. Based on this, the present application does not directly calculate the parallax of the speckle image, but first converts the speckle image into two binary images. Each pixel of the binary image only includes two values. Based on the binary image The realization of binocular stereo matching greatly reduces the calculation amount of pixel matching, and has less burden on hardware, is easy to implement, and calculates quickly, and can be used in depth sensor devices such as face recognition.
Description
technical field [0001] The invention belongs to the field of image processing, and more specifically relates to a parallax image generation method, system, electronic equipment and readable medium based on binocular stereo vision matching. Background technique [0002] The rapid development of depth sensors has brought new changes to the field of computer vision, and depth estimation information has been fully applied to solutions to problems related to autonomous driving, 3D reconstruction, behavior recognition, and liveness detection. Currently, mainstream depth sensors mainly include three types of technologies: time of flight (ToF), structured light, and binocular vision. [0003] Binocular stereo vision is based on the principle of parallax. The imaging device (Camera) is used to obtain two images of the measured environment from different positions, and the depth information is calculated by using the three-dimensional geometric principle through the pixel difference o...
