Abstract

Embodiments of the present invention provide a data encoding and data decoding method, device, and storage medium, wherein the method includes: acquiring point cloud data to be processed; encoding the point cloud data to obtain code stream data; wherein, the The code stream data includes one or more first-level data, and each of the first-level data includes one or more second-level data; the code stream data also includes identification information for identifying each level of data , the identification information includes a start code and a codeword used to identify the level to which the level data belongs. In this way, point cloud data of different levels can be randomly accessed after decoding, which improves the flexibility of data access.

Description

technical field [0001] The present invention relates to the field of data encoding and decoding, in particular to a data encoding and data decoding method, device and storage medium. Background technique [0002] In the prior art, point cloud data can be collected by devices such as lidar and laser scanners. When encoding or decoding point cloud data, the data of different levels of the point cloud data are usually used in a fixed collection sequence. Encode or decode. [0003] However, this way of encoding point cloud data in a fixed acquisition order can only be accessed one by one from the very beginning of the point cloud data stream during decoding, and random access to any level of data in the point cloud data is not possible. . Therefore, how to achieve random access to point cloud data to improve the flexibility of data access has become the focus of research. Contents of the invention [0004] Embodiments of the present invention provide a data encoding and dat...
