3D Mesh ICP and non-rigid ICP?

[stevenagl12]

Can this also be used on 3D mesh data? Also, is it possible to convert this into a non-rigid icp registration?

Hi,
I have the same problem. I test with two point cloud data, the red one has a scale of 0.8. Turns out this code failed to handle this scenario. I don't know if there is something wrong. Do you have some solutions?

If you look at the code, the author does not attempt to compute scale in this implementation, only translation and rotation. However, computing the scale for the transform is fairly straight forward as described in the paper by Umeyama.

@shuspieler If you take a look at my post here, you can see an implementation which also computes scale.

Do you have an example working with PLY's or STL files?
