Photo-based haze detection method and device

Abstract

The invention provides a photo-based smog detection method and device. The method comprises: first dividing a photo to be detected into at least two detection zones, and obtaining the hue component, the saturation component, and the lightness component of each detection zone; according to all hue components, saturation components and lightness components corresponding to the at least two detectionregions, obtaining a target hue component greater than a hue component mean value, a target saturation component greater than a saturation component mean value, and a target lightness component greater than a lightness component mean value; finally, according to the target hue component, the target saturation component, the target lightness component, a hue threshold, a saturation threshold, anda lightness threshold, determining whether smog exists in the photo to be detected. The smog detection method has the characteristics of high speed and simple calculation, is applicable to the user'sdaily smog detection, and does not require high hardware and software performance of terminal equipment.

Description

technical field [0001] The invention relates to image processing technology, in particular to a photo-based haze detection method and device. Background technique [0002] With the rapid expansion of economic scale and the acceleration of urbanization, the occurrence frequency of haze pollution weather is also increasing. When smog pollution occurs, the molecules, water vapor, and a large number of suspended particles in the atmosphere form aerosols that seriously absorb, scatter, and reflect light, resulting in reduced atmospheric visibility and serious damage to traffic order such as roads, railways, aviation, and shipping. influences. When smog pollutes the weather, a large number of pollutant particles suspended in the air will cause great health hazards to people exposed to the smog. Timely and accurate detection of haze weather is of great significance to people's daily life, normal vehicle traffic and agricultural production. Smog is mainly composed of three items:...
