چکیده مقاله
Recently machine vision technology is employed in many industrial measurement systems such as estimating endeffector pose of mechanical manipulators, which is a critical process in the kinematic calibration or feedback control of manipulators Due to this fact that the accuracy andrepeatability are two essential properties of any desired measurement system, in this article we examined and reported the accuracy and repeatability of a stereo vision 3D pose measurement system, which has been designed and implemented in Matlab software in order to estimate the pose of a parallel robot end effector Experiments were conducted in the defined depths from a 640 480 resolution stereo rigand the results were compared with another measurement system including 0 1μm precise gauge blocks The results show the acceptable accuracy of the system; 1 2775mm for Z=300mm and 1 9297mm for Z=500mm the repeatability of the system is about 1 5mm for both distance However more accurate results can be achieved by improving the stereo rig Moreover, criticality of camera calibration procedure invision based measurement systems is proved
