Method and system for detecting illegal behaviors of person standing under suspension arm, medium and electronic equipment

The invention provides a method and a system for detecting illegal behaviors of a person standing under a suspension arm, a medium and electronic equipment. The method comprises the following steps: acquiring a to-be-detected image acquired by single-path camera equipment; inputting the to-be-detected image into a suspension arm and pedestrian detection model to obtain a corresponding suspension arm detection frame and a pedestrian detection frame; when the coordinate of the pedestrian detection frame in the image is below the coordinate of the suspension arm detection frame in the image, obtaining the probability that the pedestrian is right below the suspension arm; tracking the pedestrian and acquiring an average probability value of the pedestrian in the continuous frames of images to be detected right below the suspension arm; and when the average probability value is greater than a preset threshold value, outputting a pedestrian violation warning. Each suspension arm only needs one camera, and a plurali
