Abstract
The paper discusses the key problem of measurement accuracy in a precise photo electronic measurement system, through combining the camera calibration method based on computer active vision with digital image processing technology, a method for calibrating camera internal parameters is proposed in the paper. The optics high accuracy theodolite and CCD subdivision measurement are combined in the method, and the least squares method is also used to determined the camera internal parameters under the optimum condition. The experimental results indicate: Compare with traditional camera calibration method, the operation of the camera calibration method is simple, the calibration speed is quick, and the applicable scope is broad, it can solve the problem of the distortion of CCD camera well.
