摘要： 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. The multi-pitching angle suspended panoramic space 3D display device provided in this invention allows watching by multiple persons at multiple pitching angles and horizontal 360° FOV in naked eyes, realizing space occlusion, allows exploration and interaction.

摘要： 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.

摘要： An omnidirectional-view three-dimensional display apparatus comprises a high-frame-rate projector (21), a rotatable reflector device and a cylindrical transmissive selective-diffusing screen (24). The optical axis of the high-frame-rate projector (21) is coincident with the rotating axis of the reflector device and the axis of the cylindrical selective-diffusing screen (24). The images projected by the high-frame-rate projector (21) are reflected by the reflector device to form images on the cylindrical transmissive selective-diffusing screen (24). The cylindrical transmissive selective-diffusing screen (24) can control the diffusing angle of the emergence ray, so that the left eye and the right eye of an observer can see a three-dimensional object's images in different view angles to achieve an omnidirectional-view three-dimensional display. The omnidirectional-view three-dimensional display apparatus based on the high-frame-rate projector (21) enables the eyes of observers to watch images with binocular parallax at different positions, so as to achieve three-dimensional display.
