Solving Rendering Issues in Realistic 3D Immersion for Visual Rehabilitation

摘要

When a person becomes visually impaired, intensive rehabilitation is required to learn the skills necessary to accurately interpret the sensory cues. 3D virtual immersion (3D Ⅵ) can provide a safe and rich world for rehabilitation by rendering a complex environment. 3D Ⅵ can stage challenges that can be faced with less stress than the real outdoor world. In order for 3D Ⅵ to be used efficiently, the visual rendering for people with low vision and the audio for both the blind and people with low vision must be as realistic as possible. Building a 3D environment at low cost imposes constraints both on the installation and the technical aspects. This paper describes our current work to solve projections issues for a realistic rendering when images are not aligned and deformed.
