Fog detection application in basin

Abstract

The Toushe Basin in central Taiwan is a local tourist attraction. Because the local dense fog often traps tourists in it, the main research purpose of this paper is to solve the problem of dense fog detection. Because the edge characteristics of fog images will disappear with the increase of fog concentration, analysis The proportion of the image that the edge occupies is used as the basis for fog concentration. In addition, the characteristic that the chroma of the image decreases as the fog concentration increases is used to convert the image to histogram, and the fog concentration is determined by analyzing the histogram of the image. In order to be more in line with the local fog in the Toshe Basin, the fog film data collection used in this paper is all taken on-site. The two fog concentration methods proposed in this paper are not only effective for analyzing the local area of the Toshe Basin. In addition to the fog concentration, it can also be used in places where various fogs are often generated after the threshold is adjusted.
