The mathematic model of the laser 3 - D visual sensor is established. A separated- paramneter method is proposed to calibrate the structure paramneter. Also a calibration drone is designed. In the calibrating process, complicated measurement is avoided.The proposed method simplifies the calibrating procedure. It is fast and easy to carry out. It shows that this method is practical in the visual sensors calibration by experiments.
