Abstract
Disclosed are a method for simultaneous localization and mapping, device, system and storage medium. The method comprises: acquiring a local binocular vision image and a local three-dimensional laser point cloud image that can be collected at present; preprocessing the local binocular vision image and the local three-dimensional laser point cloud image, respectively; acquiring a position and an attitude of a local binocular vision map according to the preprocessed local binocular vision image; fusing the position and attitude of the local binocular vision map with the preprocessed local three-dimensional laser point cloud image to obtain a local fusion map; and performing a global consistency optimization on a global map according to the local fusion map to obtain a dense point cloud map and output a current position information and a current attitude information in real time so as to complete the simultaneous localization and mapping (SLAM), wherein the global map is constructed according to a global three-dimensional laser point cloud image.
