True 3D display system and method based on hybrid screen

Abstract

The present invention relates to a real three-dimensional display system and method based on a hybrid screen. The system includes a driving device, an imaging device, a projection device and a hybrid screen; the hybrid screen includes a variety of display screens with different display mechanisms, and the multiple display screens share A driving device, an imaging device and a projection device; the driving device is connected with the hybrid screen, and is used to drive the hybrid screen to rotate horizontally; the imaging device is used to generate multiple images at a preset timing, and each image includes one or more images based on different displays The image content of the mechanism, each image content corresponds to a display screen; the projection device is connected to the imaging device and is set opposite to the mixing screen, and is used to project some or all types of image content in each image to the The corresponding display screens in the mixed screens, so that the mixed screen displays only some kinds of image contents or all kinds of image contents. The invention can make observers feel more real three-dimensional display effect.

Description

technical field [0001] The invention relates to a display system, in particular to a true three-dimensional display system and method based on a hybrid screen. Background technique [0002] Traditional flat-panel display technology is limited to two-dimensional images, and does not allow observers to obtain real three-dimensional depth information and complete surface characteristics. Two-dimensional plane imaging and display "force" us to use "two-dimensional window" to observe the rich and vivid three-dimensional world, which not only loses important depth information (DepthCue), cannot accurately express the three-dimensional spatial relationship, but also can only reflect the surface properties of the object. This fundamental defect of traditional two-dimensional plane imaging and display technology seriously hinders human perception of the objective world, and affects the accuracy, depth, speed and efficiency of human information acquisition, processing, transmission, ...

Problems solved by technology

[0002] Traditional flat-panel display technology is limited to two-dimensional images, and does not allow observers to obtain real three-dimensional depth information and complete surface characteristics

Two-dimensional plane imaging and display "force" us to use "two-dimensional window" to observe the rich and vivid three-dimensional world, which not only loses important depth information (DepthCue), cannot accurately express the three-dimensional spatial relationship, but also can only reflect the surface properties of objects

The main disadvantage of this technology is that the clarity of the 3D image is limited by the LED array density and the LED switching time

However, the light field 3D display technology lacks a measurable real 3D spatial relationship, and cannot reflect the accurate 3D size and mutual spatial relationship of the displayed objects in the displayed image.

[0025] It can be seen that the current traditional 3D display technology cannot seamlessly reproduce the occlusion effect, surface characteristics and real physical depth information of 3D objects that can be measured in 3D at the same time. 3D display technology is an important challenge in the field of 3D display, and it is of great significance for the penetration of true 3D display technology into various practical 3D data visualization and interactive applications.
