Abstract

The invention provides a point cloud compression method and device, a point cloud rendering method and device, equipment and a storage medium, and relates to the field of data processing. The specific implementation scheme is as follows: acquiring a target point cloud frame; dividing the target point cloud frame to obtain a plurality of point cloud point sets; performing compressed encoding on the global coordinates of point cloud points in each point cloud point set in the plurality of point cloud point sets, and determining the relative coordinates of the point cloud points in each point cloud point set. According to the implementation mode, the transmission efficiency of the point cloud data can be improved, and the visualization efficiency of the point cloud data can be improved through a pre-cached rendering object.

Description

Technical field [0001] The present disclosure relates to the field of computer technology, and specific to data processing, in particular to point cloud compression, point cloud rendering methods, devices, devices, and storage media. Background technique [0002] Due to the WEB-side rendering efficiency, the web is currently based primarily to show static three-dimensional dot clouds. For massive point cloud rendering, it is mainly to prepare the point cloud, such as layered dresses and establish an eight fork. Tree index, such as the current browser, even if less than a few dot clouds can also achieve a good display effect. For dynamic point cloud rendering, especially for real-time rendering of laser radar point clouds, the industry does not have a good solution. Inventive content [0003] A dot cloud compression, point cloud rendering method, device, device, and storage medium are provided. [0004] According to the first aspect, a point cloud compression method includes obta...
