| 摘 要： | 为了解决CCD光学系统成像的畸变量与视场角标定的问题,以径向几何畸变为主的非线性几何畸变模型为基础,通过对影响精度的参数的测量和分析,提出一种不依赖于系统内部参数的畸变量与视场角的标定方法.实验测出视场角和相对应的畸变量,再运用拟合算法给出了视场角和畸变量的变化趋势.

| Abstract: | In order to solve calibrating aberrations and visual angles in the CCD imaging optical system,based on the distortion model in which the radial geometric distortion is considered as the chief factor,a calibration method of aberrations and visual angles,which is independent of interior parameters of the imaging system,is proposed.The factors largely influencing the accurate are measured and analyzed in detail.According to the experimentally measured visual angles and the corresponding aberrations,fitting algorithm of the trend of the field angle and distortion is obtained. |
