Photovoltaic cell panel deformation prediction method based on image processing and multi-dimensional perception

Abstract

The invention provides a photovoltaic cell panel deformation prediction method based on image processing and multi-dimensional perception, and the method comprises the steps: carrying out the extraction of key points of a photovoltaic cell panel image collected by an unmanned plane, obtaining a plurality of grid regions according to the key points, counting the number of pixel points in each gridregion, obtaining a reconstructed image based on the number of the plurality of pixel points, analyzing the reconstructed image, judging whether the cell panel is abnormal or not, and judging a corresponding deformation level if the cell panel is abnormal; acquiring a plate type and a deformation grade of the abnormal battery plate and historical wind direction and wind speed data corresponding tothe abnormal battery plate, and performing calculating to obtain wind power data according to the wind direction and wind speed data; training a time convolution network by taking the wind power dataon the plate type and the time sequence as a training data set and the deformation grade as a training label, and inputting the wind power data on the plate type and the time sequence into the time convolution network after the training is completed, thereby obtaining a predicted deformation grade. The method is high in deformation detection speed, time-saving and labor-saving.
