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.

摘要： The present invention discloses a full parallax three-dimensional display device. It comprises a projector array and an orthogonal cylinder raster screen. The orthogonal cylinder raster screen comprises the first cylinder raster and the second cylinder raster. The projector array and the orthogonal cylinder raster screen are put in order. The projector array projects images on the orthogonal cylinder raster screen. The raster directions of the first cylinder raster and the second cylinder raster of the orthogonal cylinder raster screen are parallel to the x-axis and the y-axis, respectively. The advantage of the present invention is that it can generate 3D images of high image resolution and high view-field resolution. The extremely tiny view field intervals can bring completely continuous and jumping-free 3D perception for the viewer, reduce the fatigue caused by discontinuous view field in conventional 3D display, and achieve full parallax 3D display including horizontal parallax and vertical parallax.
