Calibration Technology of Optics Sensor

In active vision system, the linear illumination and vidicon sampling are widely used in obtaining the 3-D information of the objects surface distance and direction. In order to have the accurate data, we need to calibrate the optics sensor. In this paper, an optimized non-linear method was adopted to calibrate the sensor, and the mathiematics model of the method was very close to the actual performance. The result of the experiment shows us that the precision of the calibration can reach 0.1 mm. So this system is simply and practical, we recommend this system to the actual measurement.
