Abstract
This invention discloses a multi-pitching angle suspended space 3D display device with 360° FOV, comprising: a transmitted composite deflective diffusing screen, a high speed projector, an image generator, a detecting module and a rotating drive mechanism. The high speed projector projects the composite images of the 3D objects of different pitching angles and horizontal 360° views to the composite deflective diffusing screen that rotates at a high speed. The composite deflective diffusing screen is able to control the vertical deflecting and scattering angles and horizontal diffusing angle for incident rays with different angles, allowing the surrounding viewers at different height levels to see the images corresponding to their viewpoints, making the displayed 3D objects suspended over the composite deflecting scattering screen, of which the position does not change as the height of the viewpoint changes. The multi-pitching angle suspended space 3D display device with 360° FOV allows watching by multiple persons at multiple pitching angles and horizontal 360° FOV in naked eyes, realizing space occlusion, exploration and interaction.
