在錄製影片的過程中，最難克服的問題就是當以手持攝影機的方式錄製影片時，隨著拍攝時間越長而有越大的可能產生不可避免的手震現象，進而造成錄製的畫面產生相同震動，導致觀賞拍攝影片時會因畫面的不穩定感到不舒適感，所以需要防手震功能將此現象減緩，此外，當以手持3D攝影機的方式錄製3D影片時，錄製的立體影像容易受到手震的影響造成使用者後續觀賞3D影像的舒適度降低，使得手震現象對影片的影響更為突顯。 因此，本篇論文針對防手震之目的，針對一般二維影像之情況與3D立體影像之情況分別探討，並且分別提出針對二維影像防手震系統設計之硬體架構與擴展至3D立體影像之前瞻3D攝影即時防手震演算法。 在單一視角二維影像的防震處理這方面，本篇論文提出適用於高畫質單一視角二維影像即時防震處理之硬體架構，具備高規格影像處理能力，可支援Full HD 1920x1080每秒30張畫面的影像規格，操作頻率為100MHz。 對於3D立體影像防手震的開發，除了考量一般二維影像的手震現象，更要考量畫面中的內容需符合3D立體視訊顯像基本之要求，並避免因為手震的情況降低影片中的3D立體效果，綜合以上考量，本篇論文提出前瞻3D立體影像防手震演算法。除開發演算法外，此篇論文亦將 3D立體影像防手震系統實現於德州儀器(Texas Instruments) Davinci DM6446雙核心嵌入式平台，該系統包含輸出入介面的控制與演算法的執行，介面控制包含了與使用者端之間的影像轉換與將處理完的結果送至顯示端，以達到即時處理之目的。 When recording videos by handheld cameras, the recording method may cause some unwanted vibration in videos. The vibration in video may cause audiences having uncomfortable viewing experience. Audience may want to view videos where no vibration exists. Therefore, the unwanted vibration in videos needs to be removed or reduced. If cameraman films the video using a handheld 3D stereo camera, the vibration in video will cause more problems than traditional 2D monocular video. A stereo camera has two lenses on a single device. The vibrations in video may destroy the 3D relationship between left-view video and right-view video. Thus, audience may not experience deserved stereoscopic effect and feel more uncomfortable due to the destroyed 3D relationships. Efficient hardware architecture for monocular video stabilization is proposed in this thesis. The performance of the architecture supports the video specification 1920x1080 (Full HD) @ 30 fps, and the system operates at clock rate 100MHz. In order to solve the problem, different solutions for monocular video stabilization and stereo video stabilization are proposed in this thesis. Efficient hardware architecture is proposed for monocular video stabilization, and advanced 3D video stabilization algorithm is addressed for stereoscopic video. A 3D stereo video stabilization system should consider not only how to smooth the vibration in video, but also how to maintain the relationships between two cameras. Considering above issues, an advanced 3D stereo video stabilization algorithm is proposed in this thesis. A porting project is also finished in this thesis. The stereo video stabilization system is porting on Texas Instruments (TI) DaVinci DM6446 evaluation platform. This system contains control of input/output interface and process of the proposed algorithm. This work is finished for achieving the goal of real-time processing.
