kinect follow package turtlebot_follower

turtlebot_follower uses the point cloud image feed back by the depth camera to calculate the coordinates of the point cloud in a certain area as the target following point, and controls the platform movement to achieve the following function according to this coordinate and the set safety distance.

After Xiaoqiang identifies the human legs, a red ball is set as the target point in the human leg position, demo video 1

2.Ensure that Xiaoqiang is 2 meters * 2 meters in front of the open space without debris, first check the kinect angle is horizontal, if not in the horizontal state, please turn off the platform power, start the turtlebot_follower package on the Xiaoqiang host

ssh xiaoqiang@192.168.xxx.xxx
roslaunch turtlebot_follower xiaoqiangfollower.launch
