Abstract：Machine vision is used in industrial robot applications for industrial inspection, flaw detection, precision measurement
and control, automatic production lines, medicine and various hazardous applications. Based on the open source robot operating sys-
tem ROS, this paper uses Kinect binocular vision sensor to obtain 3D stereo vision data, and combines with OpenCV, OpenNI and
other open source machine vision libraries to design a low-cost machine vision system using the auxiliary machine vision tools pro-
vided by ROS. The experimental test is carried on the prototype.
