VOCs emission source oil storage tank accurate identification method based on satellite remote sensing

Abstract

The invention relates to a VOCs emission source oil storage tank accurate identification method based on satellite remote sensing. The method comprises the following steps: (1) acquiring an image with an oil tank in a remote sensing image through a satellite; (2) processing remote sensing image data with an oil tank in the acquired remote sensing images; (3) acquiring an image with the oil tank in the remote sensing images, and performing oil tank sample marking on the acquired image; (4) extracting the marked oil tank sample, and establishing a deep learning model by using a neural network; and (5) training the oil tank identification network by using the marked data, carrying out multiple times of training and optimizing the oil tank identification network, and realizing refined identification and management on the oil tank of the VOCs emission source which is distributed dispersedly by combining a satellite remote sensing monitoring technology with an air pollution enterprise. The method has the characteristics of low cost and high efficiency, effectively serves for precise pollution control of ozone pollution, and provides important technical support for environmental protection departments.

Description

technical field [0001] The invention is a method for accurately identifying VOCs emission source oil storage tanks based on satellite remote sensing. Background technique [0002] In recent years, my country's air pollution has made staged progress. The concentration of PM2.5 has dropped significantly, and the number of good days has generally increased. However, the concentration of ozone has risen instead of falling, showing a trend of increasing year by year, and the overall pollution situation is relatively severe. Ozone is produced by a series of chemical reactions of precursors such as volatile organic compounds (VOCs) and nitrogen oxides (NOx) under light conditions, which is harmful to human health and affects the air quality of the atmospheric environment. [0003] Man-made emission sources of VOCs include industrial emissions, motor vehicle exhaust, and solvent use process emissions. Among them, the unorganized emission pollution caused by volatilization and leakag...

Problems solved by technology

There are a large number of these oil tanks and they are widely distributed, and the emission intensity is relatively random. It is difficult to find all of them and manage them in a unified manner. At present, it is mainly realized through information collection and manual investigation, which not only requires a lot of manpower and material resources, but also is difficult to be comprehensive and accurate.
