Real-time outdoor pre-visualization method for videographers - real-time geometric registration using point-based model

This paper describes a real-time pre-visualization method using augmented reality techniques for videographers. It enables them to test camera work without real actors in a real environment. As a substitute for real actors, virtual ones are superimposed on a live video in real-time according to a real camera motion and an illumination condition. The key technique of this method is real-time motion estimation of a camera, which can be applied to unknown complex environments including natural objects. In our method, geometric and photometric registration problems for such unknown environments are solved to realize the above visualization. A prototype system demonstrates availability of the previsualization method.
