摘要：

Camera calibration plays and important role in 3-D measurements, computer vision, and robotics. This paper analyzes the camera model and proposes calibration methods based on the two-stage method and bundle adjustment. Both simulated experiments and real data were used to verify the methods. The calibration pattern is easy to manufacture and the control points can be identified and matched automatically. Lens distortion is considered in the calibration, and the calibration accuracy is 1:10000, satisfying the demand of high precision 3-D measurements.
