Title:
DEPTH MAP ACQUISITION METHOD AND DEVICE, AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/035627
Kind Code:
A1
Abstract:
A depth map acquisition method and device, and a computer storage medium. The depth map acquisition method comprises: acquiring a main image and a target sub-image (S110); obtaining, by means of epipolar rectification, a first rectified image and a second rectified image corresponding to the main image and the target sub-image, respectively (S120); determining a corresponding image block in the first rectified image and a corresponding image block in the second rectified image, respectively (S130); determining feature information of mapped pixels in the corresponding image blocks (S140); and determining, according to the feature information of the pixels, a depth map of the main image (S150). Epipolar rectification is used to obtain the feature information of the images, so as to obtain the depth map of the main image. The method enables parallel execution, thereby improving processing efficiency and shortening the processing time. Moreover, the computational complexity of the method is low, thus reducing hardware requirements.
