High-speed color difference correction algorithm used for UAV panoramic video system

When running a panoramic video stitching system on a UAV, he low computing power of the embedded system loaded on the UAV and the changing scenes during the flight cause a large color difference in the panoramic picture. Therefore, based on the characteristics of the UAV panoramic stitching system, we propose a novel algorithm, which has strong real-time performance, almost zero computation, and can adapt to drastic scene changes, compared with traditional algorithms. This algorithm providing a visually pleasing panoramic video color correction effect on the UAV. The experimental results show that the algorithm can effectively eliminate the color difference between the stitched images when running on the UAV, and the computing resource consumption is almost unchanged compared to when no color correction is performed.
