The embodiment of the invention provides a depth image generation method, device and equipment, and the method comprises the following steps: 1, recognizing a target region of each image in a multi-view image, and only generating a depth image corresponding to the target region, i.e., only determining a matching point pair in the target region, and only carrying out the operation of the matching point pair in the target region, thus, compared with the mode of determining all matching point pairs in the whole image and calculating all the matching point pairs, the calculation amount is reduced; and in the second aspect, performing coarse positioning on the multi-view image, and if the coarse positioning result does not meet the constraint condition set for the multi-view camera, adjusting the coarse positioning result, so that compared with coarse positioning, the positioning accuracy is improved, and a depth image generation scheme capable of considering both the calculated amount and the accuracy is provided.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and equipment for generating a depth image. Background technique [0002] The pixels in the depth image express the distance from the point in the physical space to the camera. In general, a disparity map between images collected by multiple cameras for the same scene can be calculated, and a depth map can be generated based on the disparity map. For example, in a stereo vision system composed of left and right binocular cameras, the left camera collects the left image, the right camera collects the right image, calculates the disparity map between the left image and the right image, and converts the disparity map according to the principle of triangulation for the depth image. [0003] In some related schemes, for each pixel in the left image, it is necessary to determine the pixel in the right image that corresponds to the same point in the p...
