Document Type and Number:
WIPO Patent Application WO/2023/211255
Kind Code:
A1
Abstract:
The present invention provides a point cloud compression method and apparatus. Particularly, the point cloud compression method and apparatus may: perform global motion compensation on the basis of a frame previous to a current frame; partition the current frame into a plurality of prediction units; determine a motion compensated point within a current prediction unit by performing local motion compensation on the current prediction unit; and on the basis of the motion compensated point, determine geometric information of a current point within the current prediction unit.
