Libpointmatcher is a library that implements the Iterative Closest Point (ICP) algorithm for alignment of point clouds. It supports both point-to-point and point-to-plane ICP. With the former, it is able to solve not only for a rigid transform, but also for a scale change between the clouds (that is, a similarity transform).
The library implements a set of filters to help denoise and subsample the input point clouds. It supports a variety of file types and it can be configured via both YAML files and an in-memory API. Libpointmatcher is written in C++ and fast enough for real-time application.
Note: This project is ongoing and was started during a formal employment at ETH Zurich, within the ASL.
