Abstract:
For the solution of the robotic handeye calibration, on the basis of existing research methods, a new method which combines the advantage of the highprecision of traditional calibration method with the active visual method was proposed.This method lets the robot perform orthogonal translational motion only twice and photograph the calibration plate in each position separately, so it can solve the handeye rotation matrix R, then it guides the robot move to the origin of the calibration plate, and can solve the handeye translation matrix T. Using the Pingfang 6 degree of freedom( DOF) serial robot as an experiment example, we applied the proposed method to calculate the handeye relation matrix, then used the traditional equation to analyze the accuracy of the calculation result, finally proved that the error of this method was within 1 mm. This method can achieve high accuracy and easy implement without the consideration of solving complex traditional equation.
