Vehicle tracking method based on unmanned aerial vehicle (UAV) dynamic platform

The invention discloses a vehicle tracking method based on an unmanned aerial vehicle (UAV) dynamic platform, and relates to the field of computer vision. The method is mainly technically characterized in that the method comprises the following steps: step one, receiving a video frame currently shot by a UAV, manually searching for whether the video frame comprises a target vehicle, if the video frame comprises the target vehicle, calculating position coordinates of the target vehicle in the current video frame, and if the video frame does not comprise the target vehicle, repeating the step one; step two, according to the position coordinates of the target vehicle in the current video frame, finding an optimum matching position of the target vehicle in a subsequent frame so as to realize target tracking; step three, according to the position of the target vehicle in a next video, controlling the motion direction of the UAV; and repeating the steps from the step one to the step three.
