A Camera Calibration Method in High-Precision Vision Measuring System
This paper presents a novel camera calibration method used in high-precision machine-vision-based measuring platform. This method depends on the high precision of the motion platform. Firstly we simplified the camera model to get the relation between the real-world coordinates and the pixel coordinates; secondly we move the motion platform to change the outer parameters of the camera precisely; then we detect the corresponding motion in pixel plane and get the calibration data using the simplified camera model. According to the experiment, the method’s accuracy is acceptable and has high utility value.
