Title:
PITCHING MULTI-VIEW ANGLE SUSPENSION TYPE PANORAMIC SPACE THREE-DIMENSIONAL DISPLAY DEVICE BASED ON COMBINED SCREEN
Document Type and Number:
WIPO Patent Application WO/2013/026215
Kind Code:
A1
Abstract:
A pitching multi-view angle suspension type panoramic space three-dimensional display device based on a combined screen, comprises: a combined deflection type scattering screen, a high-speed projector, an image control module, a rotation detection module, a motor and a transmission mechanism. The high-speed projector projects horizontal 360 degrees view field combined images at different pitching view angles of a three-dimensional object to different regions on the deflection type scattering screen simultaneously. Each region of the combined deflection type scattering screen controls vertical deflection and divergence angles and horizontal divergence angles of incident rays at different angles, so that observers watching around in different heights can observe stereoscopic images in accordance with viewpoint positions by two eyes, and reproduced three-dimensional scenes are suspended above the combined deflection type scattering screen. The pitching multi-view angle suspension type panoramic space three-dimensional display has the characteristics of multiple people watching simultaneously with pitching multi-view and horizontal 360 degrees full view field by naked eyes, space shading and blanking, enterable touch interaction and the like.
