Unmanned aerial vehicle high-definition image small target detecting and tracking system and detecting and tracking method thereof

The invention discloses an unmanned aerial vehicle (UAV) high-definition image small target detecting and tracking system. The UAV high-definition image small target detection and tracking system comprises a video image collecting module, and the video image collecting module is in data connection with an image processing module and a video processing result display module in sequence. The video image collecting module is used for collecting a high-frequency video frame image shot by a UAV and sending the high-frequency video frame image to the image processing module. The image processing module is used for processing the received high-frequency video frame image, detecting a moving target, and outputting the position coordinate of the moving target in the image to the video processing result display module in real time. The invention further discloses a target detecting and tracking method. The problem that the existing high-definition image small target detecting and tracking algorithm applied to actual tasks is of poor real-time performance and a small target can be hardly detected using the algorithm is solved.
