| 摘 要： | 非量测数字相机的几何标定,包括内方位元素和畸变的精确测定,直接影响其用于航空摄影测量的最终精度。本文研制出一套非量测数字相机实验室几何标定系统。该系统采用平行光管加星点板作为目标发生器,在测量出一组目标点在相机的CCD靶面上的像点坐标及对应的平行光线的入射角后,结合几何标定的数学模型,可以实现相机的高精度几何标定。采用佳能EOS 5D MarkⅡ和哈苏H3D两款典型的数字相机进行了试验与分析。试验结果验证了本文标定方法的正确性以及精度的可靠性。

| Abstract: | Geometric calibration of non-metric digital camera,including the accurate determination of interior orientation elements and distortion parameters,directly affects the ultimate accuracy of its using in aerial photogrammetry.In this paper,a laboratory geometric calibration system of non-metric digital camera is developed.A collimator and a star tester are used as the target generator in this system.After measuring locations of targets in CCD and corresponding angles of parallel lights,high precision geometric calibration can be accomplished.Two kinds of mainstream digital aerial cameras,Canon EOS 5D MarkⅡand Hasselblad H3D,are used to take experiments based on this system and the results are analyzed. Experiment results show that the method of this paper is correct and the calibration precision is reliable. |
