Problems solved by technology

[0004] At present, the air quality is mainly measured in real time through sensors installed at various locations. What needs to be understood is that although the dedicated sensor device can measure accurately, it is expensive. Based on cost considerations, it is impossible to install such sensors in all locations.
However, the distribution of air quality is not uniform, and it will change with time. Therefore, in order to be able to deal with bad air quality in time, users need to be able to know the air quality at their location anytime and anywhere, so as to Decide whether to engage in outdoor activities, or take necessary protective measures

Abstract

The invention discloses a method and equipment for determining air quality. The method includes: determining at least one key area; acquiring a reference clear image, a training image under poor air quality, and a corresponding actual air quality index at at least one position of the key area; The image and the features extracted from the training image and the actual air quality index are used to train the air quality model of the key area. Using the method and device of the embodiments of the present invention, the air quality can be determined according to the image.

Description

technical field [0001] The present invention relates to air quality measurement, and more particularly, to an image-based method and device for determining air quality. Background technique [0002] Outdoor air pollution is the most important environmental hazard that threatens human life. At present, smog and environmental pollution are becoming more and more serious, causing serious harm to human health and the environment. [0003] One of the main factors affecting air quality is fine particulate matter. For example, the value of PM2.5, which is generally concerned by people, refers to the particulate matter in the ambient air with an aerodynamic equivalent diameter less than or equal to 2.5 microns, also known as fine particulate matter. In addition, there is a PM10 value, which refers to particulate matter with an aerodynamic equivalent diameter below 10 microns. The higher the values, the more polluted the air. [0004] At present, the air quality is mainly measured ...
