My Question
Hi, I want to compare two point-clouds using the open3d library. My main goal is to do comparison between a point cloud of an object from a LiDAR scan device and another point cloud from the 3D CAD model of the same object. But for now, I'm doing comparison between point clouds of 2 similar cars to start with.
I want to know how I should compare both point clouds to get regions of similarity or dissimilarity. ChatGPT suggested to extract feature descriptors using FPFH method. But I don't know what to do next with them.
The point to note is, both point clouds will have different number of points.
