WebApr 7, 2024 · 3D LiDAR SLAM Solution. The laser SLAM scheme that relies on lidar to build maps can be divided into two categories: filter-based and graph-based optimization according to the solution method. The filter-based method is derived from Bayesian estimation theory and is an early method to solve SLAM problems. WebBased on the perception system used, SLAM can be further divided into Visual SLAM (V-SLAM) and LiDAR SLAM. Compared to Visual SLAM, LiDAR SLAM is more accurate and robust to environmental changes such as weather and illumination [6].
