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...

之前的一些neural implicit SLAM,比如iMAP、Point-SLAM、Vox-fusion、NICE-SLAM等,优化目标是depth rendering loss,可以认为是point-to-point metric。而PIN-SLAM优化目标是point-to-model SDF loss,类似于ICP中的point-to-plane metric。 根据论文《Efficient variants of the ICP algorithm》的研究,后一种方法具有更...
least an order of magnitude faster. Finally, we extend the robust formulation to point-to-plane ICP, and solve the resulting problem using a similar Anderson-accelerated MM strategy. Our robust ICP methods improve the registration accuracy on benchmark datasets while being competitive in ...
The point-to-plane variant of ICP is used for local alignment, including weightings that favor nearby points and a novel outlier rejection strategy that increases the robustness for this class of data while eliminating the burden of user-specified thresholds. Global consistency is imposed on cycles...
PCL中的点云配准(Registration)ICP算法 引言 给定两个来自不同坐标系的三维数据点集,找到两个点集空间的变换关系,使得两个点集能统一到同一坐标系统中,即配准过程。配准的目标是在全局坐标框架中找到单独获取的视图的相对位置和方向,使得它们之间的相交区域完全重叠。对于从不同视图(views)获取的每一组点云数据,需要...

2.另一种是点对面(point-to-plane)ICP算法,残差项表示为欧拉距离在目标点所在面的法线上的投影。其定义式如下(3)所示,其中T\bar{n}_{Q_{j}}表示Q_{j}点处的面法线向量的齐次坐标。 最小化这个损失函数的方法很多,本文选用迭代最小二乘法。上式中T_{TS}应该包含两部分信息,旋转和平移。为了表示本文引...
