System and method using image analysis for controlling a flight path of a surface inspection unmanned aerial vehicle

A method using image analysis for controlling a flight path of a surface inspection unmanned aerial vehicle, executed by a computer system, wherein the computer system comprises a computer and a drone connected with the computer, and the computer comprises a processor and a memory, wherein the method comprises:

• acquiring an image captured by the drone;
• performing image analysis on the acquired image;
• extracting, in a result of the image analysis, a point whose an edge variation amount is equal to or greater than a predetermined threshold;
• acquiring a position coordinate of the extracted point;
• setting, in a case where there are a plurality of points, a flight path of the drone in a manner of flying in an order of edge variation amounts of the plurality of points from large to small;
• and
• controlling the drone to fly towards the acquired position coordinate and perform capturing with a camera using light other than visible light.
