Title:
POINT CLOUD PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/010562
Kind Code:
A1
Abstract:
Embodiments of the present application provide a GAN-based point cloud processing method and apparatus. The method comprises: inputting a first point cloud into a feature extraction module to obtain a first feature of points in the first point cloud; inputting the first feature into a coarse feature extension module to obtain a second feature; inputting the second feature into a geometry generation module to map the second feature from a feature space to a geometric space to obtain a second point cloud; inputting the second feature and the second point cloud into a geometric offset prediction module to determine the offset of points in the second point cloud in the geometric space; and obtaining a third point cloud according to the second point cloud and the offset. In embodiments of the present application, the correction of the upsampled second point cloud can cause the distribution of the upsampled point cloud to be closer to the real sample, thereby facilitating improvement of the accuracy of a point cloud.
