Review on improved algorithms based on ICP algorithm

In the field of 3D point cloud registration technology, the most commonly used and the most classic registration method is Iterative Closest Point(ICP) algorithm. With the continuous development of point cloud registration technology, there have been many optimization and variant algorithms on ICP algorithm. The registration accuracy and calculation speed of the improved ICP algorithm are improved. This paper introduces the improved algorithms based on ICP algorithm, discusses their realization process respectively, analyzes their performance, and draws the conclusion of this paper.
