ICP (Iterative Closest Point)算法 ICP的目标为求出两片点云的刚性变换,点到点的ICP最早由文献[1]提出。具体算法如下: 引自文献[1]中的Sec. IV.A. 算法的核心思想是,给定一个很近的初始猜测,任何用搜索的方式匹配两组点云中距离最近的点,最后根据匹配结果求出刚性变换。该算法的收敛性可以参考文献[1]中的...

The known Iterative Closest Point (ICP) algorithm utilizes point-to-point or point-to-plane approaches. The point-to-plane ICP algorithm uses points coordinates and normal vectors for aligning of 3D point clouds, whereas point-to-point approach uses point coordinates only. This paper proposes a ...
今天我们来验证帧中继的point-to-multipoint。 试验拓扑如下: 试验拓扑说明:(拓扑做的有点烂,大家多担待点。呵呵) 试验拓扑说明:R1的物理接口不添加IP。R1的子接口S0/0.1的ip为192.168.1.1。R2的ip为192.168.1.2。R3的ip为192.168.1.3。R4的ip为192.168.1.4网络掩码都为255.255.255.0。 R1上S0/0.1的DLCI号为10...

This paper describes PLICP, an ICP (iterative closest/corresponding point) variant that uses a point-to-line metric, and an exact closed-form for minimizing such metric. The resulting algorithm has some interesting properties: it converges quadratically, and in a finite number of steps. The met...
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 ...
2 POINT-TO-PLANE ICP ALGORITHM Given a source surface and a destination surface, each iteration of the ICP algorithm first establishes a set of pair-correspondences between points in the source surface and points in the destination surfaces. For example, for each point on the source surfac...
