Description

technical field [0001] The invention relates to air pollution observation technology, in particular to an image recognition-based air pollution observation system and method. Background technique [0002] At present, air pollution has a serious impact on the health of residents, and air pollution observation plays an important role in scientific research and social early warning. [0003] Existing air pollution observations are mainly carried out by environmental monitors located at limited control points on the ground, the amount of spatially distributed data is limited, and the cost is high. [0004] The process of image recognition for image clarity is to remove the haze in the image and restore the image under fine weather conditions. The information difference between clear and fuzzy is an important parameter to reflect the state of the air. [0005] The light decreases after a certain distance of space, considering the irradiance J of parallel incident light reaching ...
