ROBOT TCP POSITIONING WITH VISION - Accuracy Estimation of a Robot Visual Control System

Abstract

Calibrated 3D visual servoing has not fully matured as a industrial technology yet, and in order to widen its use in industrial applications its technological capability must be precisely known. Accuracy and repeatability are two of the crucial parameters in planning of any robotic task. In this paper we describe a procedure to evaluate the 2D and 3D accuracy of a robot stereo vision system consisting of two identical 1 Megapixel cameras, and present the results of the evaluation.
