Abstract

The invention provides a robot indoor environment exploration,obstacle avoidance and target tracking method based on a ROS. Based on a grid map established through laser radar information,combined with local map deduction and global boundary searching,an independent exploration strategy is designed so that a moving robot can be prevented from getting into a local exploration infinite loop,and whole-indoor-environment exploration can be completely guaranteed. According to the method,real-time tracking nodes and shielding tracking nodes are designed with an improved Kalman filtering method and aMeanShift method in the ROS,the real-time problem and the complete-shielding problem of target tracking of the moving robot are solved,the computing speed of the system is increased,target search time is shortened,and the real-time requirement of tracking is met; when a target is completely shielded,the shielding tracking nodes forecast and track the target according to previous state information,and after shielding is ended,a target is newly locked,tracking modes are automatically switched,and the target is tracked through the real-time tracking mode.

Description

technical field [0001] The invention relates to the technical field of robot movement, in particular to a ROS-based method for indoor environment exploration, obstacle avoidance and target tracking of a robot. Background technique [0002] With the development of science and technology and the progress of society, mobile robot technology has been developed rapidly. At present, the application of robots has involved many fields such as hygiene, medical treatment, tour guides, education, entertainment, security, daily life, etc., and is suitable for various working environments, even dangerous, dirty and boring places. In many cases, the information of the working space is unknown. When the robot enters the unknown environment, it needs to effectively detect the working environment and construct a map of the working environment. Navigation, path planning, obstacle avoidance strategies and other operations can only be performed on the basis of the constructed map. Exploring t...
