Abstract

The present invention provides a positioning method based on environmental feature description, a mobile robot and a storage medium. The method includes: after starting, controlling the positioning auxiliary sensor to scan the surrounding environment to obtain a local feature description set corresponding to the current moment; combining the local feature description set with After comparing the pre-acquired global feature description sets, the candidate coordinates of the current location of the mobile robot are calculated according to the comparison results; the matching degree of each candidate coordinate is evaluated according to the feature information, and the candidate coordinate with the largest score is determined as the mobile robot. The global coordinates of the robot itself. The invention realizes the global positioning of the mobile robot, saves the workload of on-site deployment, and improves the convenience of use of the mobile robot.

Description

Technical field[0001]The present invention relates to the field of positioning techniques, particularly in a positioning method, a mobile robot, and a storage medium based on environmental feature.Background technique[0002]Currently, mobile robots sense the environment and its own state through sensors, and in turn, the mobile phone is achieved in an obstacle-oriented autonomous movement, which is the navigation technology of the usual intelligent autonomous mobile robot. The positioning is to determine the position of the mobile robot relative to the global coordinates and its own posture, which is the basic link of mobile robot navigation.[0003]For mobile robots, the mobile robots must be positioned after the launch, and how to quickly implement global positioning is important. The current mobile robot is multi-one to start the mobile robot to move to the initial position using a fixed position. Second, the mobile robot has started using the on-site deployment RFID, QR code and ot...
