Method and system for detecting and tracking high-altitude parabolic target in power infrastructure construction site

The invention discloses a method and system for detecting and tracking a high-altitude parabolic target in an electric power infrastructure site, and relates to the technical field of image analysis and detection, and the method comprises the steps: obtaining an electric power infrastructure site monitoring video, and extracting an image sequence containing a plurality of video frame images; according to a comparison result of the highest image brightness of the original video frame image and the set brightness, performing multi-mode Gaussian background modeling or three-frame difference method Gaussian mixture modeling on the preprocessed video frame image, and identifying a plurality of moving targets in the video frame image; performing multi-target tracking by using a Kalman filtering algorithm in combination with a Hungary algorithm, and obtaining movement tracks of a plurality of moving targets in the video frame image; target behavior analysis is carried out, whether the multiple moving targets are hig
