Open3d hidden point removal

One 、 brief introduction

Suppose you want to render a point cloud from a given viewpoint , But points from the background leak into the foreground , Because they are not obscured by other points . So , We can use the hidden point removal algorithm . stay Open3D in ,Katz The implemented method approximates the visibility of point cloud from a given view , Without surface reconstruction or normal vector estimation .

Two 、 Code implementation

For the related configuration process, please refer to the previous article ：https://blog.csdn.net/dayuhaitang1/article/details/125269607?spm=1001.2014.3001.5502, Here is only the relevant source code .
