Distribution box operation state monitoring method and system

The invention relates to the technical field of image data processing, in particular to a distribution box operation state monitoring method and system, and the method comprises the steps: obtaining a target thermogram corresponding to a to-be-monitored distribution box, and carrying out the edge detection of the target thermogram; determining a target merging area and a reference edge set corresponding to each initial edge; performing correlation processing on each initial edge and each reference edge; determining a thermal radiation index, a target heat source index, a target suppression degree and a target correction gradient value corresponding to each initial edge; performing edge detection on the target thermogram according to the target correction gradient value corresponding to each initial edge pixel point; and according to the target heat source edge image, determining whether the operation state of the to-be-monitored distribution box is abnormal. According to the invention, image data processing i
