AI Technical Summary
Technical Problem
In the existing technology, a large number of non-isolated point flags need to be encoded during the point cloud encoding process, which increases the encoding bit rate and reduces the encoding efficiency.
Method used
During the point cloud coding process, whether the isolated point coding conditions are met is judged according to the indication information of the layer to be coded. Isolated point coding is performed only when the conditions are met, thereby reducing the coding of non-isolated point flag bits.
Benefits of technology
The encoding bit rate is reduced, the encoding efficiency is improved, and the encoding time is reduced.

Abstract
The present application discloses a point cloud encoding method, a point cloud decoding method and a terminal, which belong to the field of encoding and decoding technology. The point cloud encoding method provided by the embodiment of the present application includes: obtaining geometric information of a point cloud to be encoded; based on the geometric information of the point cloud to be encoded, determining at least one point cloud slice corresponding to the point cloud to be encoded, and the point cloud slice is generated by block division based on the bounding box corresponding to the point cloud to be encoded; for the point cloud slice that meets the isolated point encoding condition, encoding the to-be-encoded layer according to the first indication information corresponding to each to-be-encoded layer in the point cloud slice to generate a target code stream, and the to-be-encoded layer is determined based on multi-branch tree division of the point cloud slice, and the first indication information is used to determine whether the corresponding to-be-encoded layer meets the isolated point encoding condition.
