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.

Description

technical field [0001] The invention relates to the technical fields of artificial intelligence, computer vision and fault detection of photovoltaic cell components, in particular to a method for predicting deformation of photovoltaic cell panels based on image processing and multi-dimensional perception. Background technique [0002] Under the action of external force, the photovoltaic cell module may have problems such as deformation of the photovoltaic cell module, and the deformation may cause a series of problems such as cell cracks and slivers inside the module that will affect the power generation efficiency of the photovoltaic cell module. However, the deformation of the photovoltaic cell panel after being pressed is small, and it is impossible to accurately and reliably judge whether the photovoltaic cell panel is deformed by naked eyes alone. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a photovoltaic pan...
