Rapid calibration for line structured light vision sensors

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.
