Photovoltaic panel target segmentation method and system under complex scene image

The invention discloses a photovoltaic panel target segmentation method under a complex scene image, and the method comprises the steps: shooting a photovoltaic panel image through an unmanned plane, marking the contour of a photovoltaic panel through a label tool, and storing the contour information of the photovoltaic panel in a JSON file; carrying out training on the marked photovoltaic panel data set through a yolov7-tiny framework, and achieving the segmentation of the photovoltaic panel; the puzzle of the photovoltaic panels needing to be numbered is cut into a plurality of images with the size of 640 * 640; the segmented image is input into a trained yolov7-tiny segmentation model; processing a segmentation result to obtain coordinates of four corner points of the photovoltaic panel; the image coordinates are converted into latitude and longitude coordinates through the known battery size and image coordinates. According to the scheme provided by the invention, the photovoltaic panel inspection efficie
