This invention proposes a registration method for point clouds with low overlap rates, effectively improving upon traditional point cloud registration methods which suffer from slow speed, low accuracy, and poor stability. The method is based on variable data sequence length least truncated squares (LTS). For the complete sequence obtained by ascending ordering the Euclidean distances of matching point pairs, since pose changes after each iteration cause variations in the distance sequence of the matching point pairs, in each iteration, using the right endpoint of the complete sequence as a reference, a dynamically changing local sequence is selected from the complete sequence based on the point cloud overlap rate and the current iteration number. This changes the position of the LTS truncated sequence on the complete sequence. When the iteration termination condition is met, the maximum length of the local sequence is the same as the length of the complete sequence. As the iteration progresses, the length of the local sequence continuously increases, thus implementing a variable data sequence length strategy during registration. Compared with traditional point cloud registration methods, this invention offers better speed, accuracy, and stability, especially when registering point clouds with low overlap rates, where the performance improvement is particularly significant.
