摘要
大气能见度的定量计算对于航空、交通以及旅游业等都有着及其重要的现实意义。研究一种简便易行的实用计算方法具有一定的社会价值。论文主要研究一种基于图像边缘处理的方法,利用图像边缘梯度、对比度、亮度等图像内在特征,并根据预设的阈值定量地判定地面预设标志物的可见性,从而达到事先自动计算能见度的目的。文中的方法通过实验数据的对比,验证了利用图像的这些内在特征计算能见度的可行性和有效性。
The quantitative calculation of atmospheric visibilities is important and has practical significance to the aviation,transport and tourism.A simple study for the practical calculation method has certain social values.This paper is mainly on the research of edge treatment methods by image edge gradient,contrast,brightness and other image inherent characteristics,and in accordance with the preset threshold quantitatively determine the default ground markers of visibility,thereby automatically calculate in advance the visibility.In the method adopted by the comparison of experimental data verify the feasibility and effectiveness of these calculations using the inherent characteristics of the images.
