Outdoor air quality estimation and early warning system based on double cameras and environment sensor data

Abstract

The invention aims to provide an outdoor air quality estimation and early warning system based on double cameras and environment sensor data. The outdoor air quality estimation and early warning system is composed of cameras, an environment sensor, an image acquisition and preprocessing module, an environment data acquisition module, a main control module, an air quality estimation module and an air quality early warning module. According to the outdoor air quality estimation and early warning system, the overall air quality estimation of an outdoor area can be obtained. Poor anti-interferencecapability and narrow measuring range of a common PM2.5 sensor in a complex outdoor environment are overcome. The air quality change trend of a period of time in the future can be judged based the data of the environment sensor, and a certain early warning effect is achieved.

Description

technical field [0001] The invention relates to the technical fields of optical ranging, image processing, intelligent control, analysis and wireless communication, and in particular to an outdoor air quality estimation and early warning system based on dual cameras and environmental sensor data. Background technique [0002] Over the past quarter century, industry and transportation have grown exponentially. The expansion of urbanization, industrialization, and industrialization has led to the continuous expansion of the city scale, the high concentration of industrial cities, and the continuous increase in the number of people and cars, resulting in continuous supply of energy and fuel demand, and increasingly serious urban air pollution. It has an important impact on the atmospheric environment, human health, ecosystems and climate change. Especially when we live in polluted air, our health will be affected. Various chemical pollutants released from stationary and mobil...
