ICP-mini-project

Small collaborative mini-project focused on implementing the Iterative Closest Point algorithm.

Introduction

C++ implementation of 3-dimensional ICP (Iterative Closest Point) method. It is originally from a Python implementation of ICP by Clay Flannigan and is rewritten into a C++ version in this project.

• ICP finds a best fit rigid body transformation between two point sets. Correspondence between the points is not assumed. Included is an SVD-based least-squared best-fit algorithm for corresponding point sets.
• In this version, exhaustive search method is used to find the nearest neighbor for each point.
• Eigen library is used for matrices operations.
