    • 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.
    • 本发明公开了一种基于组合屏幕的多俯仰角悬浮全景空间3D显示装置,包括:组合偏转漫射屏,高速投影仪,图像控制模块,旋转检测模块,电动机和驱动机构。 高速投影机将不同投影角度的3D物体和水平360°FOV的合成图像投影到组合偏转漫射屏幕的不同区域。 组合的偏转漫射屏幕的每个区域控制垂直方向上的偏转角度和散射角度以及水平方向上的漫射角度,确保不同高度水平的周围观看者的眼睛能​​够看到与其各自对应的3D图像 表示悬挂在组合的偏转漫射屏幕上的3D场景的位置。 本发明提供的多俯仰角度悬挂全景空间3D显示装置允许肉眼观察多个俯仰角度和水平360°FOV,实现空间遮挡,允许探索和交互。

    • 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.
