Crushing and grinding detection method and device for quartz sand

The invention relates to the technical field of quartz sand smashing, in particular to a quartz sand smashing and grinding detection method and device.The method comprises the steps that a color image of quartz sand powder is collected, a gray level image of the quartz sand powder is obtained, a closed contour and a dust cluster area are determined, and the dust concentration influence index and the dust shielding strength index of the closed contour are calculated; the method comprises the following steps: obtaining a dust smoothing urgent factor, constructing a quartz sand powder dedusting image, calculating an impurity detection key factor of a superpixel block, obtaining a denoising smoothing coefficient of each pixel point, obtaining a quartz sand powder denoising image, and determining the crushing and grinding quality of quartz sand. The invention aims to solve the problem that the quartz sand grinding quality detection is not accurate enough due to the fact that dust in the working environment of the
