pcregistericp
使用 ICP 算法对两个点云进行配准
语法
说明
返回一个刚体变换,用于将移动点云与固定点云进行配准。tform = pcregistericp(moving,fixed)
该配准算法基于迭代最近点 (ICP) 算法。要使该迭代过程达到最佳性能,需要根据您的数据调整相关属性。为了提高点云配准的准确性和效率,建议在使用 pcregistericp 之前,先使用 pcdownsample 对点云进行降采样。
当您选择 "pointToPlane" 或 "planeToPlane"(也称为广义 ICP 或 G-ICP)度量时,点云配准算法需要点云法线。如果输入点云的 Normal 属性为空,该函数会将其填充。
[___] = pcregistericp( 支持上述语法中的任何参量组合,且可使用一个或多个名称-值参量指定选项。例如,moving,fixed,Name=Value)pcregistericp(moving,fixed,Metric="planeToPlane") 将最小化度量设置为 "planeToPlane"。
