Method for tracking high-speed target image of unmanned aerial vehicle

The invention discloses a method for tracking a high-speed target image of an unmanned aerial vehicle. With the adoption of the method, a high-speed target can be tracked precisely in real time. By means of analysis of real-time tracking errors of the image, two existing image tracking algorithms are introduced, and fast tracking and high-precision tracking are realized with the two algorithms respectively. A high-precision algorithm result is used for correcting the fast algorithm, and the precision of the fast algorithm is improved; meanwhile, motion displacement of the unmanned aerial vehicle in the calculation period is compensated with a Kalman filtering technology, and the requirements of unmanned aerial vehicle image tracking for fastness and accuracy are met. 本发明公开了种无人机高速目标图像跟踪方法。使用本发明能够实现对高速目标的精确、实时跟踪。本发明通过对图像实时跟踪误差的分析，引入两种现有的图像跟踪算法，个实现快速跟踪，个实现高精度跟踪。通过高精度算法结果对快速算法的修正，提高了快速算法的精度，同时还利用Kalman滤波技术对计算周期内的无人机运动位移进行补偿，实现了高速无人机图像跟踪对快速性和准确性的要求。
