Title:
METHOD AND APPARATUS FOR RECONSTRUCTING POINT CLOUD MODEL, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/016996
Kind Code:
A1
Abstract:
The present invention provides a method and an apparatus for reconstructing a point cloud model, and a system, the method comprising the following steps: randomly selecting four reconstruction points that are not coplanar in a point cloud model; continuing to iteratively select other reconstruction points until reconstruction conditions are satisfied, and reconstructing the point cloud model on the basis of all reconstruction points, wherein the restoration degree for reconstructing the point cloud model is: Reward=-k·(PointNum-4)+g·VolRate, PointNum representing the number of reconstruction points currently selected, VolRate representing the volume ratio of the volume of a three-dimensional shape enclosed by all reconstruction points to the original volume of the point cloud model, k representing the proportion of the number of selected points in the reduction degree, and g representing the proportion of the volume ratio in the reduction degree. The reconstruction method further comprises the following steps: adjusting the ratio of g to k on the basis of customer needs to adjust the reconstruction conditions. The point cloud model reconstruction mechanism provided by the present invention can improve the resolution of the reconstructed point cloud model, and can control the quality of points in the reconstructed point cloud model.
