多级投影式集成成像三维显示的视场角拓展
Enhancement of viewing angle of multi-stage projection-type integral imaging 3D display
摘要
Abstract
As integral imaging has narrower viewing angles for three-dimensional reconstruction images, it can not be widely applied in three-dimensional display. To enhance the viewing angles of integral imaging, this paper develops a new three-dimensional integral imaging system with a larger view angle based on the multi-level projection technology. The system projects the element image array with different levels in parallel based on multi-projectors and obtains a construction image with a large viewing angle by three dimensional reconstruction. As compared with the conventional method with multi-axles, the proposed method has the advantages on its simply structure without other field lenses and stable system no vibration and noises. Furthermore, it is suitable for the large-scale integral imaging system. The optical experiment shows that the viewing angle of proposed integral imaging system with multi-projectors is ±35°, which is 2. 92 times that of the conventional integral imaging system and enhances the viewing angle greatly.关键词
