Isolation switch state detection method and model establishment method

The embodiment of the invention discloses an isolation switch state detection method and a model establishment method, and the isolation switch state detection method comprises the steps of obtaining a real-time motion video of an isolation switch, and capturing the real-time motion video according to frames, so as to obtain a first image and a second image; respectively splicing the first image with a preset switching-on image, a preset switching-off image and a second image to obtain a first spliced image, a second spliced image and a motion state spliced image; and respectively inputting the first splicing graph and the second splicing graph into an isolation switch state detection model to obtain a first result, inputting the motion state splicing graph into the isolation switch state detection model to obtain a second result, and obtaining the state of the isolation switch according to the first result and the second result. When the technical scheme disclosed by the invention is used for detecting the s
