Abstract

The invention provides an autonomous navigation method of robot based on video monitoring. The method comprises deployment of a navigation environment and installation of more than one monitoring cameras, and all permissible moving ranges of the robot are monitored and covered by a monitoring device. The method comprises following steps that S1, a host acquires a background image where there is no target object through the monitoring cameras and marks a static obstacle; S2, a posture recognition pattern which can be monitored by the monitoring cameras is drawn on the robot; S3, a target position and a target posture are input on the host, and the host plans a route after recognizing the pattern and the obstacle and carries out analysis and processing according to the posture; and S4, the host controls the robot to move according to the obstacle and the planned route. According to the invention, by use of the independent monitoring device, through the operation and analysis of the host, the precision and the robustness of the positioning are improved.

Description

technical field [0001] The invention belongs to the technical field of robot navigation, and in particular relates to a video surveillance-based robot autonomous navigation method. Background technique [0002] Robot autonomous navigation is the foundation and core technology to realize the intelligence of mobile robots. [0003] Most of the current robot navigation relies on the sensors carried by the robot itself to perceive its own position and posture. This positioning method is easy to cause problems such as cumulative errors, target confusion, and robot kidnapping. Furthermore, many approaches including SLAM techniques are implemented under the assumption of static landmarks and obstacles. [0004] Therefore, the existing problems in the prior art are: it is difficult for the robot to move autonomously in a complex motion environment, or the positioning accuracy and robustness are low. Contents of the invention [0005] In view of this, the present invention aims ...
