| description | The invention provides a dust pollution evaluation system, and the method comprises the steps: receiving a plurality of dust images collected by an image collection device at preset time intervals, processing the plurality of dust images, and generating a three-dimensional image digital matrix; carrying out gradient calculation on the three-dimensional image digital matrix by taking pixels as gradient step length to generate a gradient image; performing image sharpening, gray level conversion and binarization processing on the gradient image to generate a dust denoising image; and calculating the dust de-noised image to obtain a fractal dimension value and a gray average value, and calling a dust pollution index model to calculate the fractal dimension value and the gray average value to generate a dust pollution level, thereby solving the problem that a large error or distortion exists when a single variable is adopted to evaluate the dust pollution condition in the prior art.
