Why is the computation speed still slow even when I've set a relatively small expected point count for sampled model in coarse matching?

Issue Description: In Mech-Vision, the speed of “3D Coarse Matching V2” is extremely slow, despite having a relatively small number of scene point clouds and model point clouds.

As shown in the diagram, edge model matching has been selected, and the expected point count threshold is set to 200. It’s possible that this exceeds the number of points in the model point cloud. In this case, the software will use the default sampling interval of 0.001mm, which can slow down the computation speed. Lowering the value of the expected point count for sampled model can resolve this issue.
