Calibration of a robot-based measuring system

A robot-based measuring system is presented for object digitalization. In order to ensure the precision of the scanning system, a novel calibration scheme called as one-stage approach is proposed. This procedure mainly utilizes a chess board as calibration target and calibrates the range finder and hand-eye model simultaneously using the same reference points to eliminate the influences of the range finder calibration error on the hand-eye calibration. Finally, some experimental results are reported and analyzed.
