Intelligent Composition of CG and Dynamic Scene

摘要

Video composition is to integrate multiple image materials into one scene. It considerably enhances the degree of freedom in producing video programs. However, we need to adjust the viewing points and the image planes of image materials for high quality video composition, especially when some of the scenes are dynamic. In this paper, we propose an intelligent video composition technique concentrating on the composition of CG and real scene. In order to integrate the viewing points and the image planes of CGs and real scenes, we introduce the concept of virtual camera. We first automatically extract camera operation parameters of the virtual camera from real scene. Then, CG scene is regenerated according to the camera parameters of the real scene. Finally the two are composed into one scene. Various applications using the intelligent composition method are also investigated.
