在分析现有滤波方法局限性的基础上,提出了一种基于测量点法矢修正的散乱点云数据平滑处理方法,通过对特征区域和非特征区域采用不同的法矢修正方法,使光顺后的点云不但达到了非常光滑的效果,而且保持了点云的形状和特征。大量实例验证了该算法的可行性。
On the basis of analyzing the limitations of existing smoothing method,a smooth processing algorithm based on measuring point normal vector amended for scattered point cloud data is presented.By using different methods of normal vector amended on feature regions and non-feature regions,the smoothed point clouds not only achieve a very smooth effect,but also maintain their shapes and characteristics.Plenty of examples verify the feasibility of the algorithm.
