Fast Parallel Implementation of Real-Time Electronic Digital Image Stabilization System

  • 摘要: 電子數(shù)字穩(wěn)像系統(tǒng)待處理的數(shù)據(jù)量和計算量非常大,其實時性要求使得系統(tǒng)必須具有很高的數(shù)據(jù)處理速度。結(jié)合圖像視頻數(shù)據(jù)處理高度并行化、重復(fù)性處理的特征,在程序編制上,采用并行處理方法,利用單指令多數(shù)據(jù)流(Single Instruction Multiple Data, SIMD)、流水線SIMD技術(shù)和多線程設(shè)計方法。采用塊匹配法進行運動估計,以總絕對差作為匹配準則,以菱形搜索與三步快速搜索相結(jié)合的綜合搜索策略,減少了運算量,進一步加快了處理速度。同時,使用Kalman低通濾波方法去除圖像的高頻抖動,而保留了平滑的全局運動,保證了系統(tǒng)的有效性和魯棒性。通過這些措施,在普通PC機上實現(xiàn)了系統(tǒng)的高效實時處理。
