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.

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 … http://library.isr.ist.utl.pt/docs/roswiki/pcl(2f)Handbook.html cryptographically secure uuid
