The invention discloses an on-line monitoring method and device for line induction electricity-taking icing and external damage prevention images. The method comprises the following steps: obtaining icing pictures of a wire body and a connection fitting; the boundary contours of the insulator before and after icing are extracted through an edge detection algorithm, and the icing thickness of the insulator is calculated in combination with the camera imaging principle; and obtaining power transmission line icing monitoring big data by using an anti-interference algorithm, and forming a power transmission line anti-icing capability model. Clear icing pictures of a wire body and a connecting fitting can be shot in a short distance, boundary contours of the insulator before and after icing are extracted through an edge detection algorithm, the icing thickness of the insulator is calculated in combination with a camera imaging principle, the identification problem which cannot be solved in a traditional waving and
