METHOD AND APPARATUS FOR RECONSTRUCTING POINT CLOUD MODEL, AND SYSTEM

摘要

The present invention provides a point cloud model reconstruction method, apparatus, and system. The method includes the following steps: randomly selecting four non-coplanar reconstruction points in the point cloud model; keeping iteratively selecting other reconstruction points successively until a reconstruction condition is met, and reconstructing the point cloud model based on all reconstruction points, where a reduction degree of the reconstructed point cloud model is: $\mathrm{Reward}=-\mathrm{k}\cdot \left(\mathrm{PointNum}-4\right)+\mathrm{g}\cdot \mathrm{VolRate},\mathop{\mathrm{image}}$ where PointNum represents a number of current selected reconstruction points, VolRate represents a volume ratio of a volume of a solid shape formed by all of the current reconstruction points to an original volume of the point cloud model, k represents a proportion of the number of the selected points in the reduction degree, and g represents a proportion of the volume ratio in the reduction degree. The reconstruction method further includes the following step: adjusting a ratio of g to k based on user requirements to adjust the reconstruction condition. The point cloud model reconstruction mechanism provided in the present invention can improve resolution of a reconstructed point cloud model and control quality of points in the reconstructed point cloud model.
