.Rapid calibration for line structured light vision sensors[J].Optoelectronics Letters,2006,2(3):175-178 Rapid calibration for line structured light vision sensors YANG Pei XU Bin-shi WU Lin [1]National Key Laboratory of Advanced Welding Production Technology, Harbin Institute of Technology, Harbin 150001, China [2]National Key Laboratory for Remanufacturing, Beijing 100072,China Abstract:       The mathematic model of the line structured-light 3-D vision sensor was established. A separating-parameter method was proposed to calibrate the structure parameter, and a calibration target was designed. In the calibrating process, complicated measurement is avoided and the calibration is fast and easy to carry out, which simplifies the calibrating procedure. The experimental results show that the space measurement accuracy is better than 0.15 mm. This method is high efficient and practical in vision sensors calibration.
