Title:
METHOD AND APPARATUS FOR PROCESSING POINT CLOUD DATA, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/017134
Kind Code:
A1
Abstract:
The present disclosure provides a method and apparatus for processing point cloud data, and an electronic device and a storage medium. The processing method comprises: performing rasterization processing on point cloud data in an obtained target scenario to obtain a raster matrix, a value of each element in the raster matrix being used for representing whether a corresponding raster has a target point or not, and the target point representing any point corresponding to the point cloud data; generating, according to the raster matrix and size information of an object to be recognized in the target scenario, a sparse matrix corresponding to said object; and determining the position of said object in the target scenario on the basis of the generated sparse matrix.
