摘　　要：本文利用三维激光扫描技术对相机进行自标定,以其结果作为参考。选用传统标定方法的Tsai两步法、Weng两步法作为标定模型,以点云数据辅助进行相机标定,并对其标定结果进行分析,取得了很好的实验结果。通过精度评定论证了这种以点云数据辅助、采用传统标定方法作为标定模型的标定方法的可行性。In this paper, a 3D laser scanning technique is used to calibrate the camera, and the results are the reference. Tsai two steps method and Weng two steps method are used as the calibration model. The camera calibration was carried out with point cloud data. Then the calibration results were analyzed, and it turns out that the experimental results were obtained. The feasibility of the traditional calibration method of the point cloud data aided is demonstrated by the accuracy evaluation
