使用攝影機追蹤的實景合成電腦動畫創作研究
Applying Camera Tracking as a Tool to Composite Computer Animation onto Video Editing
摘要
爲了滿足閱聽者對影像真實感與想像力的需求，實拍影片結合虛擬D電腦動畫元素，儼然已成爲數位影像發展的新趨勢。時至今日，好萊塢的電影特效在結合實拍影片與D動畫已是司空見慣，然而高成本的製作，卻令小型的工作室或獨立的創作者望之卻步，無疑的也阻礙了影像創作者創意空間的發揮。 隨著電腦科技的進步，D動畫製作成本亦大幅降低，投入實景D電腦動畫製作的人也日益增加。然而多數製作者仍受限於“攝影機追蹤”技術的運用，而使作品的視覺效果大打折扣。因此本創作研究即以“攝影機追蹤”爲核心，分析實拍影片中攝影機的追蹤及應用，並以實務創作進行佐證說明，以提供創作者實景D電腦動畫一個完整的製作參考依據，使其作品能達到更好的合成視覺效果。

To satisfy the audiences' pursuing of image realism and content imagination, the combination of live footage and computer animation has become one of the mainstreams in digital content creation. This new visual effects tool has widely adopted in Hollywood, however, due to the high production cost, we rather seen small studio or independent artists devote their works in this field. This certainly hinders the expanse of some creative ideas. As computer technologies advance, the production cost of D computer animation dwindles, and more artists devote combining live footage and computer animation respectively. Unfortunately most of the artists are not familiar with ”camera tracking”. As a result, the visual effects impact of their works are not well displayed. Thus, this study focuses ”camera tracking” technology, and analyses the camera tracking and its application of virtual camera in live footage video editing. Coupling with this study, a video editing animation work was created as an example to demonstrate research results. Through this study, we hope it provides a good reference for artists to better display the visual effects of their video editing works.
