An Overview of SLAM

Simultaneous Localization and Mapping (SLAM) based on LIDAR and Visual SLAM (VSLAM) are key technologies for mobile robot navigation. In this paper, the SLAM algorithm based on these two types of sensors is described, and their advantages and disadvantages are comprehensively analyzed and compared. In order to better achieve active navigation and positioning, path planning and obstacle avoidance, the advantages of both should be brought into full play. In the end, the future development direction of mobile robot is discussed.
