Find rigid 3D transform between two 3D point sets

Hi, I have two 3D point sets with known correspondence and I want to find rigid transform between them. I did not find suitable function in OpenCV to do it. Can anybody tell me how to do it？

Thanks.

maybe you can use the ICP algorithm from contrib/surface_matching

ICP does not require the correspondence. Since I already know the correspondence, maybe some more efficient methods exist, I think.

correspondences

oh, i missed that, does it mean, you have point "pairs" ?
