Three-Dimensional Point Set Registration Problem

The three-dimensional point set registration problem is a crucial challenge in computer technology. As a widely adopted algorithm for addressing this issue, the Iterative Closest Point (ICP) algorithm has garnered significant attention from researchers. This paper presents a novel approach to categorizing and summarizing various improvements and optimizations of the ICP algorithm for 3D point set registration, focusing on three key aspects: selection of registration elements, determination of registration strategies, and solution of error functions, with relevant algorithm implementations and key function descriptions.
