- Abstract:
-
Visual SLAM refers to simultaneously localizing itself and reconstructing the environment map using cameras as the only external sensor. The quality of the map created by SLAM plays a decisive role in the performance of the subsequent automatic localization, path planning, and obstacle avoidance. This paper introduced the feature-based visual SLAM and direct visual SLAM methods; the major symbolic achievement of visual SLAM; the main research laboratory of SLAM; and the method of SIFT, SURF, and ORB feature detection and matching, key frame selection. In addition, this paper summarized the loop closure detection and map optimization that removed the accumulated error. In the end, the development tendency and research highlights of SLAM were discussed and the advantages and disadvantages of monocular SLAM, binocular SLAM, and RGB_D SLAM were analyzed.
