摘要
在图像辅助导航中,航空照片都具有不同程度的几何畸变和辐射畸变,给图像内容的辨别带来误辩,通过灰度差值算法,把系列航空图像变换为同一坐标系下的图像几何畸变,再通过改进的最大熵算法,实现图像辐射畸变校正,使图像"热点"区域明显。
In image guided navigation, Due to radiometric and geometric distortions of images from photography, it can mislead the content of the image, Image series are finally converted into the same coordinate system. Based on the analysis of correction algorithm, a much better one is presented, which proved to be effective in the correction of radiometric image distortion. In this way to make the 'hot' area obvious.
