Image detection method for morphological parameters of atmospheric pollution particles

Abstract

The invention provides an image detection method for morphological parameters of atmospheric pollution particles. The image detection method comprises the following steps: acquiring digital image dataof the atmospheric pollution particles based on optical three-dimensional scanning; pre-processing such as de-noising and binarization is carried out on the acquired image; atmospheric pollution particulate matter segmentation and positioning are carried out; calculating to obtain atmospheric pollution particulate matter morphological parameters; the method has the advantages of wide measurementrange and more measurement objects; Morphological parameters of atmospheric pollution particles can be directly measured and calculated; the method can accurately position the atmospheric pollution particles and calculate the morphological parameters of the atmospheric pollution particles, effectively obtains the morphological and type information of the atmospheric pollution particles, and provides convenience for a user to know the atmospheric pollution condition in time.

Description

technical field [0001] The invention relates to the technical field of air pollutant detection and computer image processing, in particular to an image detection method of air pollution particulate matter morphological parameters, and in particular to an image detection method of air pollution particulate matter and an accurate calculation method of morphological parameters. Background technique [0002] Air pollutants refer to harmful substances (also known as pollutants) contained in the atmosphere. With the rapid development of our country's society and economy, as well as the rapid development of science and technology and the continuous acceleration of industrialization, the problem of air pollution has attracted more and more attention. However, in the process of people's life and industrial production, a large amount of pollutants will be discharged into the atmosphere, resulting in a decline in the quality of the atmospheric environment. When the concentration of ai...

Problems solved by technology

At present, the measurement of particle size of atmospheric particles, including shape and scale, mostly adopts scanning electron microscopy and other methods. There are many unfavorable factors such as long measurement time, many measurement steps, measurement accuracy is greatly affected by subjective factors, and samples are damaged during the measurement process. The particle size of air pollution particles is not precise enough to achieve in-situ measurement of particle morphology
