Method, system and equipment for detecting looseness of bolt structure of electric iron tower and medium

The invention discloses an electric iron tower bolt structure looseness detection method, system and device and a medium, and relates to the technical field of power transmission and distribution. The method comprises the steps of obtaining a target image of an electric iron tower bolt structure; performing angle classification on the target image of the electric iron tower bolt structure by adopting an angle classification model to obtain a shooting angle; the angle classification model is a ResNet model obtained by training an electric iron tower bolt structure sample image set; if the shooting angle is a side view angle, performing looseness judgment on the target image of the electric iron tower bolt structure by adopting a target detection model to obtain a judgment result; the target detection model is a DETR model obtained by training based on a small sample learning method; and if the shooting angle is a front view angle, performing looseness judgment on the target image of the electric iron tower bol
