Digital Dome Film Technology System And Key Technologies

Digital full-dome film system is such a revolutionary kind of film. That in playing it can reach fore-and-aft 180°and right-and-left 360°of visual field. Its quite extensive visual field makes the audiences feel be on the scene. The immersion effect is so greatly strong that even without 3-D glasses the film can build stereovision. This dissertation puts forward a new method about using multicenter image producer which is based on computer cluster technology, and high-resolution projector group, to construct a digital full-dome film playing system. The display of 180°hemisphere projection has been successfully realized.The domestic research and exploitation of digital full-dome film system is in its initial stage yet. This dissertation integrates current technology and suggests audacious methods, combining a lot of exploitation achievements and implementation experience. It concludes the key technology from a structural angle and advances some actualization scheme.
