AbstractThis paper presents a vision based feedback system framework of position and orientation measurement for parallel robot. It is
composed of image acquisition, camera calibration, position and orientation measurement, and parameter feedback. Single camera is used for image
acquisition. A kind of 2-DOF parallel robot is used as control object, and Haar-like feature detection is presented as a method of rough object
tracking. In order to acquire the real parameters based on invariants of trapezia, the special feature points on the object are determined. An
inverse-kinematics of robot is used to get the control signals of every motor. And the feasibility of the system is proved by simulation experiments.
Key wordsHaar feature; 2-DOF parallel robot; pose measurement
