Abstract:
To complete a film, it needs to go through the process to capture the actual actor’s motion and compose it with virtual environment. Due to the excessive cost for production or lack of post-processing technology to make the film, however, it is mostly conducted by manual labor. The actor plays his role depending on his own imagination at the virtual chromakey studio, and at that time, he has to move and consider the possible collision with or reaction to an object that does not really exist. And in the process of composition applying Computer Graphics(CG), when the actor’s motion does not go with the virtual environment, the original image may have to be discarded and it is necessary to remake the film. This paper presents and realizes depth-based real-time 3D virtual image composition system to reduce the ratio of remaking the film, shorten the production time, and lower the production cost. As it is possible to figure out the mutual collision or reaction by composing the virtual background, 3D model, and the actual actor in real time at the site of filming, the actor’s wrong position or action can be corrected right there instantly.
