基于过曝区域转移的点云空洞补全方法OA

To address the issue of data loss caused by point cloud holes on highly reflective surfaces in structured-light 3D reconstruction,a point cloud hole completion method based on overexposure region transfer was proposed.By utilizing the characteristic that the position of overexposure regions transfers before and after object rotation,and combining image processing with point cloud coordinate system transformation,this method maps the overexposure regions of the pre-rotation image to the non-overexposure regions of the post-rotation image,and then reconstructs the point cloud of this region and stitches it with the original point cloud to achieve point cloud hole completion.Experimental results show that the proposed method can effectively complete point cloud holes.
