这种方法随着迭代次数的增加会逐步逼近真值。迭代算法相比于闭合解法更加耗时,它可能会抵消PointToPlane相比于PointToPoint所带来的速度优势,对旋转矩阵的近似在初值不佳时误差较大。 闭合解 [2]提出了一种闭合求解法,它并没有直接求解问题(1),而是将旋转矩阵的约束丢弃,将问题转变为一个线性最小二乘问题:(4)argm...

The method has the advantages of the classic point-to-plane ICP method, but extends this to higher dimensions. For demonstration purposes, this paper will focus on a RGB-D sensor that provides colour and depth measurements simultaneously and an optimal error in higher dimensions will be minimized...
The registration algorithm requires point cloud normals when you select the "pointToPlane" or the "planeToPlane" (also known as Generalized-ICP or G-ICP) metric. If the Normal property of the input point cloud is empty, the function fills it. example [tform,movingReg] = pcregistericp(mov...

The Iterative Closest Point (ICP) algorithm that uses the point-to-plane error metric has been shown to converge much faster than one that uses the point-to-point error metric. At each iteration of the ICP algorithm, the change of relative pose that gives the minimal point-to-plane error ...
