Power grid safety early warning method and device based on image monitoring

The invention discloses a power grid safety early warning method and device based on image monitoring, and relates to the technical field of image processing, and the method comprises the steps: collecting a visible image sequence and an infrared image sequence of target power grid equipment; collecting a smoke characteristic information sequence; identifying and identifying the abnormal temperature area to obtain an abnormal temperature image sequence; performing consistency verification analysis on the smoke image, the different-temperature image and the smoke feature information to obtain multiple pieces of consistency information; carrying out data value analysis and extraction; and carrying out safety early warning analysis to obtain a safety early warning level, and carrying out safety early warning. The technical problems that the efficiency, the real-time performance and the accuracy of power grid safety early warning are poor due to the fact that the operation state and the environment of power grid
