Problems solved by technology

These display methods have their own advantages and disadvantages. For example, the suspension distance of the mirror with two reflective surfaces that have the ability to gather light is limited. The three-dimensional displays realized by researchers from Japan and Zhejiang University have limited display accuracy and cannot be accurately imaged in space. Korean researchers’ The display image quality is not ideal and there are problems with spatial focus
[0004] It can be seen from the above that the traditional naked-eye 3D display cannot provide a suitable AR / VR interaction solution
The new floating display technology may meet the technical requirements in the future, but currently there is no naked-eye 3D floating display solution with high quality and accurate spatial imaging capabilities that can meet the interactive needs of AR / VR

Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] The object of the present invention is to propose a naked-eye three-dimensional image that has high imaging quality, accurate spatial positioning capability, real-time rendering, and can be directly suspended in the air without resorting to projection media.

[0024] Such as figure 1 , in a specific embodiment of the present invention, shows a schematic diagram of the overall framework of a new three-dimensional floating display system. Generally, it includes a three-dimensional image projection source A1, a half-mirror A2 with light-gathering ability on the reflective surface, and a mirror A3 with light-gathering ability on the reflective surface; the three-dimens...

Abstract

The invention provides a novel three-dimensional suspension display system and a real-time light field rendering method. Compared with the traditional light field imaging technology, the novel three-dimensional suspension display system and the real-time light field rendering method have the advantages that remote suspension display is achieved, the imaging center of the display system is located outside a whole display, and no barriers exist between an image and an observer; in addition, the light field density of a displayed image is increased through multiple three-dimensional image projection sources, and the corresponding rendering algorithm can achieve real-time rendering.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional display, and more specifically, relates to a novel three-dimensional floating display system and a real-time light field rendering method. Background technique [0002] At present, the traditional naked-eye 3D display technology can provide a display solution that can be directly observed, has stereo vision, and can be viewed by multiple people. But this display method confines the image inside the display (for volumetric displays) or near the display (for integrated imaging, holographic displays, and light field displays). Due to the display of the display hardware, the current naked-eye display technology cannot display a three-dimensional image that is too far away from the display. This dependence of 3D images on display hardware leads to limitations in 3D interactive capabilities. Especially in the field of AR / VR, it is difficult for the observer to directly touch or opera...
