Title:
MOTION SEGMENTATION METHOD AND APPARATUS FOR POINT CLOUD DATA, COMPUTER DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/099530
Kind Code:
A1
Abstract:
A motion segmentation method for point cloud data, comprising: acquiring multiple frames of point cloud data; performing point cloud motion segmentation on the point cloud data to obtain a point cloud motion segmentation result; performing ground filtering processing on each frame of point cloud data to obtain multiple frames of non-ground point cloud data; performing cluster analysis on the multiple frames of non-ground point cloud data to obtain a 3D bounding box corresponding to each frame of non-ground point cloud data; performing occlusion analysis on the 3D bounding box to determine a point cloud motion state corresponding to the 3D bounding box; and when the point cloud motion state is dynamic, updating the point cloud motion segmentation result according to the non-ground point cloud data corresponding to the 3D bounding box to obtain a target point cloud motion segmentation result.
