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.

Provided are a method and system for upgrading firmware. The method includes: an upgrading control single board receives a firmware upgrading request from a master control single board, wherein the firmware upgrading request carries firmware upgrading parameter information; the upgrading control single board determines, according to the firmware upgrading parameter information, a sublink to be upgraded corresponding to the firmware upgrading parameter information; and the upgrading control single board acquires, from the master control single board, firmware upgrading data corresponding to the sublink to be upgraded, and upgrades, by adopting the firmware upgrading data, one or more pieces of firmware on the sublink to be upgraded. According to the solution, under a power-on state of a bare single board to be upgraded, remote firmware upgrading can be performed for the single board, so that the risk of influence of firmware upgrading operation on normal running of the system is lowered.
