Abstract

The invention belongs to the technical field of robots, and particularly relates to a robot map updating method and device, a computer readable storage medium and a robot. The method comprises the steps : in the mapping process of a robot, generating all sub-graphs in sequence, wherein each sub-graph is a local map comprising a plurality of frames of data; constructing a global map according to each sub-graph; executing loop-back optimization, and selecting a target sub-graph from all the sub-graphs, wherein the target sub-graph is a sub-graph, changed before and after loop-back optimization,of the pose of the robot in the frame data; and updating the global map according to the target sub-map to obtain an updated global map. According to the method, only partial updating of part of the sub-graphs is involved, the calculation amount is greatly reduced, the map updating efficiency is improved, map updating can be completed in a short time, the influence of map updating on robot positioning is reduced, and the situation that the pose of the robot is wrong or even lost is avoided.

Description

technical field [0001] The present application belongs to the technical field of robots, and in particular relates to a robot map updating method, device, computer-readable storage medium and robot. Background technique [0002] Simultaneous Localization And Mapping (SLAM) technology is the core technology of mobile robots. Based on the complex and changeable factors of the robot's working environment, a stable and efficient SLAM technology solution plays a decisive role in the application of mobile robots. [0003] Existing map construction solutions are mostly suitable for smaller scenarios, but for large scenarios such as shopping malls, office buildings, and parking lots, due to the huge amount of frame data cached by the SLAM system, and considering the limited computing resources of robots, the global It takes a long time to update the map. At this time, if the robot is still walking, there is a risk that the robot will not be able to locate and cause the robot's pose...
