Transformer substation maintenance personnel verification method and device based on edge calculation

The invention relates to a transformer substation maintenance personnel verification method and device based on edge computing, and the method comprises the steps: obtaining a personnel code bound with an access control card code after an access request signal is received; on the basis of the obtained personnel code, querying to obtain a first characteristic standard value and a second characteristic standard value corresponding to the personnel; after the entering request signal is received, activating the camera device, acquiring a video stream shot by the camera device, and extracting a video stream as a face video to be recognized; based on the face video to be recognized, extracting a plurality of target detection images to form a target detection image set; for each target detection image in the target detection image set, selecting the target detection image closest to the first feature standard value as a target verification image; and based on the target verification image, calculating a second featu
