Generalized-ICP(GICP)将 Point-To-Point和Point-To-Plane ICP用统一的概率框架描述,并拓展为Plane-to-Plane ICP(GICP)算法,这个算法精度更高,对点于点之间最大距离阈值 d_{max} 更加不敏感,对初值更加不敏感…
三、 Point-to-plane 方法简介 Point-to-plane是一种ICP变体通过利用曲面法线信息来提高性能(单从描述上看我还没看出来如何提高性能?难道收敛变快了?不会吧?),此方法与标准ICP方法的不同之处在于算法的第11行替换为: 其中, 是点 处的法向量 四、GICP方法介绍 GICP方法同样是针对图1中算法的第11行进行修改,...
(简称GICP)是Point Cloud Library(PCL)中的一个类,用于点云配准。它是迭代最近点(Iterative Closest Point,ICP)算法的一种变体,通过考虑点云的拓扑结构来提高匹配的准确性,特别适用于有序点云和含有噪声的数据。 2. pcl::generalizedIterativeClosestPoint 的工作原理...

modified GICPtrimmed methodIn this paper, we introduce a modified Generalized Iterative Closest Point (GICP) algorithm by presenting a coarse-to-fine strategy. Our contributions can be summarized as: Firstly, we use adaptively a plane-to-plane probabilistic matching model by gradually reducing the ...
gicp gicp的出现就是专门为了解决icp面临的问题,其实gicp并不复杂,icp失效的原因在于,他只是在考虑每一个点的残差,并没有考虑每个点的局部特征。 要把icp改为gicp其实非常简单,只需要将欧氏距离替换为马氏距离就可以了。 使用马氏距离建立最小二乘法匹配: ...
