Title:
BINOCULAR STEREO MATCHING METHOD, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/231173
Kind Code:
A1
Abstract:
The present application discloses a binocular stereo matching method, a device, and a storage medium. The method comprises: obtaining a first view and a second view; respectively inputting the first view and the second view into two feature extraction modules to obtain a first feature map and a second feature map; inputting the first feature map and the second feature map into an effective attention module to obtain a second large-scale recombination map, the effective attention module being used for redistributing a content weight of the second feature map according to the first feature map; constructing a hybrid cost volume according to the first feature map and the second large-scale recombination map; and inputting the hybrid cost volume into a disparity regression module to obtain a disparity map. According to the present application, by providing the effective attention module, the content weight of the second feature map is redistributed according to the first feature map, the accuracy of the hybrid cost volume constructed according to the first feature map and the second large-scale recombination map is high, and the accuracy of the disparity map can be improved.
