近年來，特效電影為電影工業的一大主流，這些特效場景必須利用影像合成的技術將演員合成至背景場面之中。為了合併出完美的合成影像，除了物件的亮度及顏色的強度需要經過校正外，另一個重點則是物件大小，根據置入的位置不同，物件的大小也要有所調整，因此需要利用圖片的深度來做大小的計算。因此本論文首先利用雙目立體視覺(Stereo Vision)和特徵點去計算出背景圖片的深度，接者針對物件的亮度及色彩強度做調整，並利用內插法配合深度資訊去做大小的調整，最後採用Possion演算法將校正過的物件融入背景之中。在本研究中，能夠有效利用深度資訊和背景資訊來對物件做校正，並且使用Possion editor來建構一套完整的影像編輯系統。 Over the last decade, the special effects movie is the most popular in the film industry. These special effects need to use the image combination to combine the avatars and the background. In order to get a perfect combination image, it has two key point: the illumination and the pixel intensity of the object and the object’s size. According to the different location, the object size also need to adjust. So that, it need the depth of the picture to measure the size. In our research, first, we use the stereo vision and the feature points to calculate the depth of the background. Second, to adjust the illumination and the pixel intensity of the object. Third, use the bilinear interpolation and the depth information to adjust the size. Finally, using the Possion algorithm to make the object melt in background naturally. In our research, we can use the depth and background information to adjust the object, and use the Possion editor to construct a complete video editing.
