Abstract: The gradient distribution of aero-photograph is analyzed.An improved method of estimating blur kernel and BRL(Bilateral Richardson-Lucy) deconvolution algorithm are introduced.Then,an image restoration method of motion-deblurring from an aero-photograph is presented,and used to process some motion-blurred aero-photographs.Experiment results show that the image displacement is removed effectively,and the vision quality of aero-photographs is improved obviously by using this method.Especially the important edges are preserved.

Key words: aero-photograph, gradient distribution, motion-deblurring, deconvolution

摘要: 分析了航空影像梯度分布特征,介绍了一种改进的模糊核估计方法和BRL(Bilateral Richardson-Lucy)反卷积算法,并提出了一种同时具有模糊核估计和BRL反卷积功能的单幅航空影像去除运动模糊方法,最后用运动模糊航空影像进行了实验验证和分析。结果表明,该方法可有效去除像移,改善模糊航空影像视觉效果,特别是可以保护图像中重要边缘信息。
