An Iterative Closest Point (ICP) library for 2D and 3D mapping in Robotics - norlab-ulaval/libpointmatcher
内容概要:文章深入探讨了激光雷达点云数据的ICP(Iterative Closest Point)配准算法,这是一种常用于机器人导航、三维重建和自动驾驶等领域的重要技术。文中详述了ICP算法的基本原理、计算流程及其在Matlab环境下的源码实现,并进行了详细的实验验证和结果分析。ICP通过迭代计算两组点云的最佳刚性变换(旋转和平移),使它们在...
libpointmatcher is a modular library implementing the Iterative Closest Point (ICP) algorithm for aligning point clouds. It has applications in robotics and computer vision. The library is written in C++ for effeciency withbindings in Python. ...
ICP 有两种经典的error function,参考open3d registration tutorial: point-to- point 2. point-to- plane 这个就不多说了,印象里 motivation 是扫描到的是物体表面而不是孤立的点,所以点到点的loss其实是不太合理的,匹配点应当距离很近并且尽可能的与法向量垂直,基于表面连续的假设。 DICP 的 error function 可...
