WebAs you can see, PCL uses the "PFHSignature125" type to save the descriptor to. This means that the descriptor's size is 125 (the dimensionality of the feature vector). Dividing a feature in D dimensional space in B divisions requires a total of B D bins. The original proposal makes use of the distance between the points, but the implementation of PCL … Web19 de fev. de 2024 · I have a point cloud with PCL. I want to split the point cloud into many small surfaces each containing, let's say, 120 points. It's not about just making chunks of points from the cloud. I think one way to do this is to get normals and collect approximately equal normals under one set and call this a small surface.
