Title:
POINT CLOUD PROCESSING METHOD AND APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/037091
Kind Code:
A1
Abstract:
Embodiments of the present application provide a point cloud processing method and apparatus, a computer device, and a storage medium. The point cloud processing method comprises: in a decoding stage, acquiring encoded data of a point cloud, and parsing the encoded data to obtain shift data, wherein the shift data is obtained by performing shift processing on target encoding information of the point cloud in an encoding process of the point cloud; and performing shift reconstruction on the shift data to obtain reconstruction encoding information of the target encoding information. The point cloud processing method comprises: in an encoding stage, acquiring target encoding information of a point cloud, and performing shift processing on the target encoding information to obtain shift data of the target encoding information; and encoding the shift data. According to the embodiments of the present application, shift processing is performed on the target encoding information, so that the amount of data needing to be encoded in the encoding stage of the point cloud can be reduced, the amount of data needing to be decoded in the decoding stage of the point cloud can be reduced, and thus, the encoding and decoding efficiency of the point cloud can be improved.
