WebOur ICP implementation expects a dictionary of point sets as an input. [12]: coords_dict = { 'A': A.coords, 'B': B.coords, 'C': C.coords } First, we initialize an ICP object. The algorithm iteratively matches the ‘k’ closest points. To limit the ratio of mismatched points, the ‘radii’ parameter is provided.
