Abstract

The invention relates to a solar cell panel rainbow pattern detection method based on dual-light integration, and the method comprises the steps: obtaining an RGB image and a thermal imaging image ofa photovoltaic power station through a dual-light integrated camera, processing the RGB image of the photovoltaic power station, and obtaining a solar cell panel surrounding frame; according to the three-channel pixel value mean value corresponding to each solar cell panel surrounding frame and the thermal imaging image of the photovoltaic power station, rejecting the solar cell panel surroundingframes which do not meet the requirements, and carrying out temperature anomaly analysis on the solar cell panel RGB image surrounded by the solar cell panel surrounding frames which meet the requirements to obtain an abnormal RGB area; judging whether the abnormal RGB area is a strip-shaped area or not, and if yes, judging whether rainbow lines exist or not according to the pixel difference degree. The method combines the advantages of the RGB image and the thermal imaging image, takes the advantages of the RGB image and the thermal imaging image, greatly reduces the impact from an interference factor, and improves the recognition accuracy of the rainbow pattern of the solar cell panel.

Description

technical field [0001] The invention relates to a method for detecting rainbow stripes of a solar battery panel based on dual-light integration. Background technique [0002] The lower corners of solar panels are prone to dust accumulation. If these dust accumulations are not cleaned in time, under the action of external environment such as high temperature, rain, impurities, etc., they will develop into rainbow-shaped markings (i.e. rainbow stripes) that cannot be erased, which will affect the performance of solar cells. The power generation efficiency and service life of the board. At present, the position where the rainbow pattern appears on the solar panel is generally at the dust accumulation on the lower edge, and it is positively related to the amount of dust accumulation. The thickness and width of the dust accumulation determine the shape of the rainbow pattern. Some solar panels have temperature differences in the morning. There is water accumulation on the lower ...
