| Research Abstract |
Several systems have been developed for synthesizing virtual environments from real photographic images. This type of system can be considered as an alternative way of generating virtual worlds as opposed to using computer graphics with 3D CAD models, This system can also easily provide very realistic sensations of being present 3D space. For example, the authors have developed a system called the "Virtual Dome" . However, this system only allows the user to look around at previously recorded images from fixed viewpoints. This means that the user is not allowed to move around freely while changing viewpoints continuously in the virtual environment. Without any special algorithms to provide the user with images from all possible viewpoints would require enormous amounts of recorded image data. Using this developed system, we could implement realistic virtual worlds at a reasonable cost without using very complex and complicated 3D models.
