Photovoltaic panel hot spot detection method and system

The invention provides a photovoltaic panel hot spot detection method and system, and belongs to the technical field of image processing, and the method comprises the steps: firstly calculating an RGB channel feature value of a photovoltaic panel hot spot image, then partitioning the to-be-processed photovoltaic panel image to obtain image sub-blocks, and according to the distance between the channel value of each pixel point on the image sub-blocks and the RGB channel feature value, calculating the RGB channel feature value of the to-be-processed photovoltaic panel hot spot image. According to the photovoltaic panel hot spot detection method and the photovoltaic panel hot spot detection system, the similarity of the channel values during hot spot imaging is utilized to directly evaluate whether the hot spots exist in each image sub-block, and the photovoltaic panel hot spot detection method and the photovoltaic panel hot spot detection system are small in calculation amount. 本发明提供了一种光伏板热斑检测方法及系统，属于图像处理技术领域，本
