How to register points by using iterative closest point (ICP) between two 3D models?

Hello.

I have two 3D models and I want to register the points between these two models. How can I do that by using iterative closest point (ICP)? Thank you.

Here is the link to the documentation for the function "pcregrigid" that registers two point clouds using ICP algorithm.

You can also refer to the File Exchange Link that discusses a kind of Iterative Closest Point (ICP) registration algorithm for 3D point clouds.

Thank you for the suggestion. I got an error after running the code. From what I understand, the object needs to be point cloud object but what I have is stl file. can I still use the same code?
