I have reconstructed two 3D models in the scene. I want to convert them into point clouds and then calculate a comprehensive distance between the two models.
How should I achieve this? For example, if I convert each model into 10 points and also convert the other model into 10 points, then I can use the Kabsch algorithm in this case.
If the models are vtkPolyData, as you would get from model mrml nodes in slicer, then there are vtk filters that compute distance. E.g. hausdorff distance
