摘要
实际光学镜头所成的图像一般存在有几何变形,尤其是在大视场短焦距成像系统中,给图像的后续处理带来诸多问题。在以径向畸变为主的几何畸变模型基础上,提出了一种简单精确的图像校正方法。实验证明该方法是图像几何修正的有效方法,具有良好的工程应用价值。
Generally there is geometrical distortion in optical lens imaging, especially with a large-field, short focal length lens. This will bring about a good many problems in imaging process subsequently. Considering the radical geometry distortion as a primary factor, a simple and speedy method of distortion correction is given. Further more, experimental results indicate that the method proposed is effective and valuable in the engineering application.
