Solar panel dust detection and power influence evaluation method and device

The invention discloses a solar panel dust detection and power influence evaluation method and device, and the method comprises the steps: obtaining a plurality of training pictures, and determining a mapping relation between a dust threshold value and a vacancy ratio of each divided region; acquiring a shot real-time image of the surface of the solar panel, and converting data of the real-time image from an RGB color space to an HSV color space; determining the proportion of the sand and dust data in each region according to a pre-divided sand and dust threshold value of each region; and determining a real-time vacancy ratio corresponding to the real-time image according to the mapping relationship between the sand and dust threshold value and the vacancy ratio of each region and a preset fitting function in combination with the proportion of the sand and dust data in each region. Through the image processing technology, the sand and dust condition on the surface of the solar cell panel can be monitored in r
