Embodiment 1
[0080] Embodiment one, as figure 1 As shown, a method for real-time positioning of UAV target key points, comprising the following steps:
[0081] S1: Obtain the monitoring image of the drone, select a current frame image from the monitoring image, and perform down-sampling processing on the current frame image to obtain a first grayscale image;
[0082] S2: Obtain the current frame predicted position of the target center of the drone according to the first grayscale image, and calculate the current frame accurate position of the target center according to the current frame predicted position;
[0083] S3: Perform binarization processing on the current frame image to obtain a second grayscale image;
[0084] S4: In the second gray-scale image, determine the current frame suspicious area of the target key point in the current frame image according to the accurate position of the current frame; and determine the current frame suspicious area and the current frame accurate positi
Embodiment 2
[0143] Embodiment two, such as Figure 9 As shown, this embodiment is a schematic structural diagram of a real-time positioning system for UAV target key points.
[0144] A real-time positioning system for key points of an unmanned aerial vehicle, comprising a monitoring unit 11, a down-sampling processing unit 12, a computing unit 13, a binarization processing unit 14, and a search unit 15;
