vtkImplicitPolyDataDistance2A thread-safe version of the originalvtkImplicitPolyDataDistance, where it is possible to return both the closest point and the gradient. It is pretty slow and should be optimized using meta-programming at some point. ...
Pointclouds are loaded at run time by passing in two plain text files as command line arguments. File format is one point per line, separated by commas (e.g. "1, 2, 3 \n 4, 5, 6 \n"). This code uses Eric Jang's Fast 3x3 SVD library provided from his GitHub page to generate...
ICP 算法的第一步就是找到 Source 点云与 Target 点云中的对应点(corresponding point sets),然后针对对应点,通过最小二乘法构建目标函数,进行迭代优化。 1.1 估计对应点(Correspondences estimation) ICP 称为 Iterative Closest Point,顾名思义,是通过最近邻法来估计对应点的。 对Source 点云中的一点,求解其与 ...
迭代最近点算法(ICP)算法是Lidar SLAM中常用的点云配准方法,可以求解两组点云之间的相对位姿。 本文对最基本的ICP算法进行了介绍和简单实现,并集成为一个简化版的Odometry。 1 原理 1.1 问题:给定两组点云 X={x1,x2,⋯,xm}P={p1,p2,⋯,pn}(1) 求解两组点云之间的先对位姿R,t。问题的特殊性在于:1...
该篇文章是通过李群和李代数左扰动模型求取雅可比矩阵,然后通过非线性最小二乘方法对点云配准迭代ICP算法进行的一个推导,这是这篇文章与SVD求解详解的不同之处。由于作者认识和理解有限,文章存在众多不足之处,同时请谅解作者不严谨的态度,请大家不吝指教!
