【摘要】:在現(xiàn)有算法無法滿足無人機視頻實時壓縮傳輸需求的應(yīng)用背景下,該文提出一種新的低復(fù)雜度無人機(Unmanned Aerial Vehicle,UAV)視頻實時壓縮算法,利用無人機視頻的背景平面性、運動一致性等特點,建立仿射模型描述視頻的全局運動,并根據(jù)模型參數(shù)進行視頻壓縮。實驗結(jié)果表明,與現(xiàn)有壓縮算法H.264相比,該算法在保證壓縮性能的前提下,大量減少了壓縮時間,可滿足大多數(shù)情況下無人機視頻傳輸?shù)馁|(zhì)量要求和實時性要求。
[Abstract]:Under the background that the existing algorithms can not meet the demand of UAV video real-time compression, this paper proposes a new real-time video compression algorithm for UAV (Unmanned Aerial vehicle UAV) with low complexity, which utilizes the background planarity of UAV video. The affine model is established to describe the global motion of the video, and the video is compressed according to the parameters of the model. The experimental results show that compared with the existing compression algorithm H.264, the proposed algorithm can greatly reduce the compression time and meet the quality and real-time requirements of UAV video transmission in most cases.
