Among the sensors used for environment recognition, the camera is the most popular and powerful. However, there are several limitations in the camera-based teleoperation of a mobile robot.

In this paper, a 3D leaf position measurement method based on stereo vision is proposed for guidance of an autonomous spray robot. A binocular stereo vision system is constructed by a single camera, which can move up and down on the vertical arm of the robot. With this vision system, a disparity map that contains the depth information of the plant leaves are calculated from the acquired image pairs...
