Description

Technical Field

[0001] This invention relates to the field of holographic projection technology, specifically to a holographic deck volumetric light field display stage. Background Technology

[0002] Existing holographic projection technology is generally divided into two types: one is 180-degree holographic projection, which displays people, objects or logos in the form of digital content; the other is 360-degree holographic projection, which integrates and produces multi-angle, all-round 360° stereoscopic floating images based on the principle of light reflection and the visual error of the human eye.

[0003] Both of the above holographic projection technologies require pre-recording of the projected image before projection. Regarding the display medium, they typically use rigid screens such as plastic or metal panels. In terms of holographic display and interaction, only simple dialogue is possible, and real-time interaction with the projected virtual character is not possible. Furthermore, data transmission primarily uses ordinary data transmission, which is slow and cannot achieve real-time interaction and display. All of these factors limit projection performance.

[0004] Therefore, how to improve the convenience of holographic projection technology by using a holographic deck volume light field display stage is a problem that urgently needs to be solved by those in the field. Summary of the Invention

[0038] Figure 1 A schematic diagram of a holographic deck volumetric light field display stage provided by an embodiment of the present invention is shown. Figure 1 As shown, the holographic deck volumetric light field display stage includes:

[0039] Support structure 1, the support structure 1 being used to provide the image to be displayed on the display screen;

[0040] A housing disposed on one side of the support structure 1;

[0041] The display screen group 2, the first display screen 3, and the holographic medium group 4 are disposed inside the housing. Both the display screen group 2 and the first display screen 3 are used to receive and display the image to be displayed provided by the support device 1.

[0042] The display screen group 2 is located on both sides of the same side of the first display screen 3;

[0043] The holographic medium group 4 is located inside the first display screen 3 and the display screen group 2. The holographic medium group 4 is used to directionally refract the light emitted by the image to be displayed displayed by the display screen group 2 and the first display screen 3 to the point light source field, so as to achieve the effect of displaying the image to be displayed holographically in the point light source field.

[0044] In this embodiment, a support structure is used to provide an image to be displayed to the display screen; a housing is disposed on one side of the support structure; a display screen group, a first display screen, and a holographic medium group are disposed inside the housing, the display screen group and the first display screen are both used to receive and display the image to be displayed provided by the support device; wherein, the display screen group is located on both sides of the same side of the first display screen; the holographic medium group is located inside the first display screen and the display screen group, the holographic medium group is used to directionally refract the light emitted by the image to be displayed displayed by the display screen group and the first display screen onto the point light source field, so as to achieve the effect of displaying the image to be displayed holographically in the point light source field, which can improve the convenience of holographic projection technology.

[0045] In an optional embodiment of the present invention, the display panel 2 includes:

[0046] The second display screen and the third display screen are independent screens, and the second display screen and the third display screen are symmetrically arranged based on the center line of the first display screen 3.

[0047] The holographic medium group 4 includes:

[0048] A first holographic medium and a second holographic medium are symmetrically arranged based on the center line of the first display screen 3. One end of the first holographic medium and the second holographic medium are connected together, and the other end of each is connected to the first display screen 3. The first holographic medium is used to refract the image to be displayed displayed on the second display screen, and the second holographic medium is used to refract the image to be displayed displayed on the third display screen.

[0049] In this embodiment, when providing volumetric video, directional rays are generated using microdisplay technology combining multiple lens arrays. A significantly increased pixel density, narrowing the emission angle, and improved interconnection methods drive key components for the optical capture of opaque particles in a point-source field (photophoresis). These key components, combined with point-source lenses, generate aberrations in the light field image to capture heated microparticles within the light field. By using a light field lens, aberrations create dark areas that can capture particles. As particles are illuminated within the light field, rapidly moving points create a line, wireframe, or surface, moving at a refresh rate of at least 10 times per second. Computer-controlled imagery is used to present volumetric video within the light field, illuminating particles with the three primary colors of light (RGB) to track the image. This involves 3D capture of motion images of the real world, volumetric video capture, and light field-based rendering. This enables real-world holographic experiences at resolutions up to millions of pixels, including modular video walls for live events and large installations, but not limited to those described above.

[0069] In another optional embodiment of the present invention, the first display screen 3, the second display screen, the third display, the first holographic medium and the second holographic medium are all rectangular structures.

[0070] In this embodiment, the rectangular structure can make the holographic deck volumetric light field display stage more stable.

[0071] In the above embodiments of the present invention, a support structure is used to provide an image to be displayed to the display screen; a housing is disposed on one side of the support structure; a display screen group, a first display screen, and a holographic medium group are disposed inside the housing, wherein the display screen group and the first display screen are both used to receive and display the image to be displayed provided by the support device; wherein the display screen group is located on both sides of the same side of the first display screen; the holographic medium group is located inside the first display screen and the display screen group, and the holographic medium group is used to directionally refract the light emitted by the image to be displayed displayed by the display screen group and the first display screen to the point light source field, so as to achieve the effect of displaying the image to be displayed holographically in the point light source field, which can improve the convenience of holographic projection technology.

[0072] Simultaneously, the structure of the holographic deck volumetric light field display stage provided in this invention embodiment can also employ a holographic deck light field system to project holographic images using a projector, forming a new projection device and a holographic projection environment. This device includes a projector, a light field area, a series of point light sources, and a volumetric video deck presentation system. Utilizing environmental hardware, the projection achieves 180-degree spatial coverage, presenting a more three-dimensional viewing effect. A projector is a device that can project images or videos onto a screen. It can be connected to computers, video compact discs (VCDs), high-density digital video discs (DVDs), Blu-ray discs (BDs), game consoles, digital video cameras (DVs), etc., through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and entertainment venues. Depending on their operating methods, there are different types, such as cathode ray tubes (CRTs), liquid crystal displays (LCDs), and digital light processing (DLP). The projector is placed at the top and bottom, and the projection medium surrounds the entire space, arranged according to actual needs.

[0073] The projector is positioned at the top, and through the application of technology, virtual characters are projected onto the volumetric video deck in real time. The projector system is controlled in real time via a holographic projection system and a remote control system. This device can be applied to the entire space without limitations.

[0074] By generating a large number of viewpoints, a "real image" of an object projected off the optical screen is recreated. These viewpoints can change perspective and position as accurately as in the real world. This is achieved through direct emission, modularity, and coupling of a flat display surface with a complex series of waveguides. The surrounding objects seen while moving in any direction maintain motion parallax, as well as accurate reflection and refraction, and the eye can freely focus on objects formed in space. Even without any physical object, the brain perceives "this is real." The screen consists of a series of display point light source fields; connecting the image seen by the eye to the surface of these small spheres, any line touching the surface at an angle of 90° will be accurate. The screen provides a pixel correct only for each angle.

[0077] Furthermore, those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are meant to be within the scope of the invention and form different embodiments.
