一种基于亮通道的无人机航空影像匀光算法

随着无人机的发展,无人机航空影像的应用越来越广泛。受无人机搭载相机自身因素和摄影时的外部条件等影响,无人机航空影像经常表现出亮度不均衡的现象。为了改善无人机航空影像的亮度分布,通过分析无人机航空影像特点,介绍了单幅无人机航空影像存在不均匀光照的原因,基于亮通道假设介绍了一种影像匀光算法。

With the development of unmanned aerial vehicle （UAV）, the application of UAV aerial image is more and more widely. Jnmanned aerial vehicles （UAV） aerial images often show brightness imbalance due to the influence of UAV＇s camera and external conlitions. In order to improve the luminance distribution of UAV aerial images, this paper introduces the reasons of the single UAV aerial mages brightness imbalance through the analysis of the UAV aerial image features, and introduces an image smoothing algorithm based on light channel.
