摘要

Based on the characteristics of line structured light sensor

a speedy method for the calibration was established. With the coplanar reference target

the spacial pose between camera and optical plane can be calibrated by using of the camera's projective center and the light's information in the camera's image surface. Without striction to the movement of the coplanar reference target and assistant adjustment equipment

this calibration method can be implemented. This method has been used and decreased the cost of calibration equipment

simplified the calibration procedure

improved calibration efficiency. Using experiment

the sensor can attain relative accuracy about 0.5％

which indicates the rationality and effectivity of this method.
