[Iterative closest point](https://en.wikipedia.org/wiki/Iterative_closest_point) (ICP) is an algorithm to minimize the difference between two clouds of points, which means it can be used to reconstruct 2D or 3D surfaces from different scans. It is an algorithm that tries to solve the generic problem of [Point-Set registration](https://en.wikipedia.org/wiki/Point-set_registration)
# Implementations
- The library [libpointmatcher](https://github.com/norlab-ulaval/libpointmatcher?tab=readme-ov-file)
- The lightweight library [simpleICP](https://github.com/pglira/simpleICP)
