A Multi-Camera Calibration Technique Based on Active Vision

To solve the camera Parameter calibration problem in stereo vision, A Multi-camera parallel calibration method is proposed on the base of camera intrinsic parameters model. Based on the principles of active vision, using the measurement bracket to fix four cameras in the linear independent locations and the shunt device to drive cameras´ simultaneous shooting, consequently the calibration method achieve the same effect as the shooting by the three times independent linear translation. According to the method, the calibration experiments are designed, and the experimental results show that the method has medium-precision and simple operation, without using high-precision calibration reference objects.
