Abstract
This invention discloses a combined-screen-based multi-pitching angle suspended panoramic space 3D display device comprising: a combined deflective diffusing screen, a high speed projector, an image control module, a rotation detecting module, a motor and a drive mechanism. The high speed projector projects the composite images of the 3D objects of different pitching angles and horizontal 360° FOV to different areas of the combined deflective diffusing screen. Each area of the combined deflective diffusing screen controls the deflecting angle and the scattering angle in the vertical direction and the diffusing angle in the horizontal direction, ensuring that the eyes of the surrounding viewers of different height levels can see the 3D images corresponding to their respective positions, representing the 3D scene suspended over the combined deflective diffusing screen.
