摘要
This article addresses the visual servoing of a rigid robotic manipulator under fixed camera configurations. The control goal is to move the robot end-effector to a visually determined target position by using a vision system equipped with two fixed cameras. A general image-based controller is proposed to achieve "precise" positioning in, the absence of measurement noise. Based on the "epipolar constraint" [1], we have shown that the overall closed-loop system, using redundant image features, is exponentially stable provided that camera model imprecision is small.
