摘要
为修补三维激光点云中的复杂空洞,本文提出了一种基于摄影测量原理的修补算法。与常规利用空洞与空洞周围点云的关系修补空洞的方法相比,该方法对于复杂空洞的修补可靠性更高,通用性更强。实验结果表明,该空洞修补算法适用于大面积、复杂的点云空洞,能较好地保持原三维物体的细节特征。
To repair the complex holes of laser scanning point cloud,this paper presented an algorithm based on photogrammetry.Compared with conventional methods which repairs holes using the relationship between holes and point cloud around the holes,this method was more reliable and more versatile.Experimental results showed that the algorithm applicable to large-scale and complex hollow of point cloud could better maintain the original details of the characteristics of three-dimensional objects.
