I am supposed to take 2 input point clouds and compare them to figure out if there are any differences in them in terms of lets say the location of the components, etc.
I want to know how I should compare both point clouds to get a similarity or dissimilarity score and compare it with some threshold value to check if it passes or not.
I thought of doing the feature extraction of both point clouds using FPFH (Fast Point Feature Histograms) method and then compare them. I don't if this is the best way or not. Then, I tried RANSAC based feature matching using feature vectors (generated from FPFH method) of both point clouds, but I am not getting any meaningful result.
I have no prior knowledge of working with point clouds and this is my first time working with it. What can I try next?
