A method for determining sag of an electricity transmission line based on image recognition is provided. In the method, an image of an electricity transmission line in a target area captured by an unmanned aerial vehicle is acquired and coordinates of a catenary corresponding to the electricity transmission line is extracted from the image. A catenary curve equation is constructed based on the extracted coordinates of the catenary and a complete catenary curve is drawn according to the catenary curve equation. A sag expression of the catenary is obtained based on the complete catenary curve and the catenary curve equation. A derivative of the sag expression is calculated to obtain a maximum sag.
