Abstract
The invention involves a sort of curved film projection system, including a rendering surface, a projection screen, a real scene rendering model of image system, a rendering model of projection system that renders the projection the image rendered by the rendering model of image system on the rendering surface, and projecting devices that projects the image finally rendered by the rendering model of projection system onto the projection screen through optical lens. The viewing direction and angle from observer's eyes to the rendering surface is consistent with that to the projection screen: The image system rendering model can be reversible on optical path with the projection system rendering model. The curved film projection system not only reduces the rendering cost, but also produces lifelike experience for audience.
