[0053] like Figures 1 to 3 As shown, this utility model provides an immersive holographic digital electronic sand table display system.

[0054] An immersive holographic digital electronic sand table display system includes:

[0055] An immersive display space and an immersive display system 1 set within the immersive display space. The immersive display space is a box-shaped space enclosed by a top surface, a bottom surface, a vertical surface, and two side surfaces. The immersive display system 1 includes a display panel 11 and a screen controller 12, a splicing processor 13, and a broadcast control server 14 connected to the display panel 11. The display panel 11 includes a top display panel 111, a bottom display panel 112, a vertical display panel 113, and two side display panels 114 respectively set on the top surface, bottom surface, vertical surface, and two side surfaces of the box-shaped space.

[0056] The lifting holographic projection film structure 2 has one end rotatably mounted on the top surface of the box-shaped space. In the internal immersive display state, the other end of the lifting holographic projection film structure 2 flips upward and attaches to the top display screen 111. In the external projection display state, the other end of the lifting holographic projection film structure 2 flips downward and overlaps the bottom display screen 112, where the viewer stands.

[0057] In one specific embodiment, such as Figures 1 to 3 As shown, the top surface of the box-shaped space is equipped with a top display screen 111, the bottom surface of the box-shaped space is equipped with a bottom display screen 112, the vertical surface of the box-shaped space is equipped with a vertical display screen 113, and the two sides of the box-shaped space are respectively equipped with side display screens 114.

[0058] In one specific embodiment, such as Figures 1 to 3As shown, the top display screen 111 is connected to the vertical display screen 113 at a 90-degree angle. The top display screen 111 is connected to one side display screen 114 at a 90-degree angle. The top display screen 111 is connected to another side display screen 114 at a 90-degree angle. The bottom display screen 112 is connected to the vertical display screen 113 at a 90-degree angle. The bottom display screen 112 is connected to one side display screen 114 at a 90-degree angle. The bottom display screen 112 is connected to another side display screen 114 at a 90-degree angle. It should be noted that this embodiment only shows one angular relationship between adjacent display screens and does not limit the angle between adjacent display screens. Those skilled in the art can choose other angles according to their needs.

[0059] In one embodiment, the top display screen, the bottom display screen, the vertical display screen, and the two side display screens are all LED display screens.

[0060] In one specific embodiment, the top display screen plays the image to be projected, while the bottom display screen, the vertical display screen, and the two side display screens each play the complete background image to enhance the immersive effect. It should be noted that this embodiment only illustrates one possible content arrangement for the display screens; those skilled in the art can arrange the content of each display screen according to their needs, and this invention does not limit such arrangements.

[0061] In one specific embodiment, based on the collected data, existing 3D modeling software is used to render lighting and shadow effects to simulate background scenes under different time (daytime, nighttime) and weather (sunny, rainy, foggy) conditions.

[0062] In one embodiment, the lifting holographic projection film structure can project the content of the top display screen, so that the image of the top display screen is projected onto the lifting holographic projection film structure to form a three-dimensional holographic projection.

[0063] In one embodiment, the depth-of-field effect of holographic imaging is adjusted by adjusting the tilt angle of the lifting holographic projection film structure.

[0064] In one embodiment, such as Figure 2 as well as Figure 3As shown, the immersive display space and display panel assembly are located within the imaging room. The imaging room contains top mounting brackets 3, bottom mounting brackets 4, and vertical mounting brackets 5 located on the top, bottom, facade, and two sides of the immersive display space, as well as two side mounting brackets (not shown in the figure, but their structure is similar to the other mounting brackets). A suspended ceiling 6 is also installed in the imaging room, with one end connected to the top mounting bracket 3 and the other end fixed to the ceiling of the imaging room. It should be understood that a room is a basic unit of interior space in a building. The imaging room is the room where the immersive display space and display panel assembly are to be installed. The top mounting brackets and the suspended ceiling are used together to fix the top display panel, the bottom mounting brackets are used to fix the bottom display panel, the vertical mounting brackets are used to fix the vertical display panel, and the two side mounting brackets are used to fix their respective side display panels.

[0065] In one embodiment, such as Figure 3 as well as Figure 4 As shown, the imaging room is also equipped with a suspender rod 7, which passes through the middle of the top display screen 111 and is connected to the lifting holographic projection film structure 2.

[0066] Specifically, the LED display screen consists of multiple LED display modules (chassis). Several display modules are removed from the middle of the top display screen. One end of the suspension rod 7 is fixed to the ceiling of the imaging room, and the other end of the suspension rod 7 is removed from the area where the top display screen is removed ( Figure 3 It passes through the area indicated by the middle arrow A and connects to the lifting holographic projection film structure 2. It should be understood that this embodiment does not limit the number of display modules to be removed, and those skilled in the art can select according to imaging requirements.

[0067] In one embodiment, such as Figures 2 to 4 As shown, the lifting holographic projection film structure 2 consists of a holographic imaging film 21 and clamping components 22 respectively disposed at both ends of the holographic imaging film 21; wherein, the clamping component 22 at one end of the holographic imaging film 21 is connected to the hanging rod 7, and the clamping component 22 at the other end is connected to the lifting structure 8.

[0068] In one specific embodiment, the clamping component is a clamp made of high-transparency glass, and the clamping component is provided with a hanging ring.

[0069] In a preferred embodiment, the holographic imaging film is equipped with a holographic phantom imaging film (phantom film, phantom film, reflective film), which works on the principle of reflective imaging. It should be noted that, compared to existing holographic films, the holographic phantom imaging film has better parameters such as light transmittance, resulting in a better display effect.

[0070] In one embodiment, such as Figure 2 as well as Figure 3 As shown, the lifting structure 8 includes: a retraction rope 81 connected to the other end of the holographic imaging film clamping assembly, and a drive device 82 for driving the retraction rope to extend and retract.

[0071] Specifically, the hanging loop of the clamping component at the other end of the holographic imaging film is connected to the retraction rope. The driving device can be any device with rope retraction function, such as a motor-driven rope retraction device, and is not limited here.

[0072] When the drive device winds the retraction rope, the other end of the lifting holographic projection film structure 2 flips downwards; when the drive device releases the retraction rope, the other end of the lifting holographic projection film structure 2 flips upwards. It should be noted that this invention achieves the switching between external holographic projection viewing and internal immersive viewing through the lifting structure.

[0073] In one embodiment, such as Figure 1 As shown, there are multiple screen controllers 12 and broadcast control servers 14; the top display screen 111, bottom display screen 112, vertical display screen 113, and two side display screens 114 are each connected to a screen controller 12. Each screen controller 12 is connected to a splicing processor 13. Each display screen is also equipped with a broadcast control server 14. Each broadcast control server 14 is connected to the splicing processor 13.

[0074] Specifically, the on-site video signal sources, such as the broadcast control server, are connected to the input board of the splicing processor (splicer) via their respective video cables. The output board of the splicing processor then sends the signals to each screen controller (transmitter box), and the screen controller outputs its signals to the corresponding display screen via a network cable.

[0075] The broadcast control server is used to play scene content from the 3D modeled and rendered digital twin software and to run the interactive tracking system software. The stitching processor divides and processes the scene content from each broadcast control server and outputs it to designated display screens in separate regional windows. The screen controller is used to display the images processed by the stitching processor on the corresponding display screens.

[0076] Switches are used for signal transmission. By intelligently forwarding data, optimizing bandwidth utilization, and enhancing network management, they ensure fast, stable, and secure communication between devices.

[0077] In one embodiment, such as Figure 1As shown, the immersive holographic digital electronic sand table also includes a motion capture module. This module connects to the splicing processor and each screen controller via a switch. The motion capture module contains a wireless communication unit for connecting to external control devices. Specifically, the wireless communication unit can use wireless communication methods including, but not limited to, infrared, radio frequency, Bluetooth, and Wi-Fi. When a user inputs operation commands using an external control device (e.g., a remote control pen), the external control device converts the commands into encoded signals. The wireless communication unit of the motion capture module receives the encoded signals, which are then decoded by the controller within the motion capture module to execute the corresponding operation commands. Operation types include, but are not limited to, switching slides, controlling video playback, and marking on the display screen. The motion capture module can also respond to voice operation commands.

[0078] It should be understood that the screen controller, broadcast control server, switch, splicing processor, and motion capture module can be placed inside or outside the imaging room, and this utility model does not limit this. Those skilled in the art can select the appropriate model or type of screen controller, broadcast control server, switch, splicing processor, and motion capture equipment according to actual needs, and this utility model does not limit this either.

[0079] The principle of this invention for achieving internal immersive display will be explained below:

[0080] like Figure 5 As shown, the human eye's vertical field of view ranges from 60 to 135 degrees. When looking straight ahead, the clear vertical field of view is approximately 60 degrees, while it reaches 75 degrees when looking upwards and about 60 degrees when looking downwards. The vertical field of view for both eyes is even wider, approximately between 120 and 140 degrees. Assuming a 1.74-meter-tall person stands at the center of the bottom display screen of an electronic sand table and looks ahead, the field of view covers 130°, the screen boundaries are not visible, and there will be a good immersive experience.

[0081] like Figure 6 As shown, the horizontal visual field of the human eye ranges from 120 to 188 degrees. When looking straight ahead, the range that can be clearly seen is approximately 120 degrees, while peripheral vision can perceive areas of about 60 degrees to the sides. The maximum horizontal visual field of a single eye is 156 degrees, while the maximum horizontal visual field of both eyes is 188 degrees. In addition, the overlapping visual field of both eyes is 124 degrees, which means that objects appear three-dimensional within this range.

[0082] Imagine a 1.74-meter-tall person standing at the center of the bottom display screen of an electronic sand table, looking ahead. The human eye has a 188° field of view, within which the screen boundaries are invisible, resulting in a good sense of immersion.

[0083] The principle of holographic imaging achieved by this invention will be explained below:

[0084] like Figure 7 As shown, the human eye's vertical field of view ranges from 60 to 135 degrees. When the eyes are looking straight ahead, the clear vertical field of view is approximately 60 degrees, while it reaches 75 degrees when looking upwards and about 60 degrees when looking downwards. The vertical field of view for both eyes is even wider, approximately between 120 and 140 degrees. Assuming a 1.74-meter-tall person stands 1 meter away from an electronic sand table viewing a holographic image, their field of view covers 144 degrees, and the viewing angle for the holographic image is 46 degrees. Peripheral light can be surrounded by the screen, and the holographic image falls within a clear vertical field of view.

[0085] like Figure 8 As shown, the horizontal field of view of the human eye ranges from 120 to 188 degrees. When looking straight ahead, the range that can be clearly seen is approximately 120 degrees, while peripheral vision can perceive areas of about 60 degrees to the sides. The maximum horizontal field of view for a single eye is 156 degrees, while the maximum horizontal field of view for both eyes is 188 degrees. Furthermore, the overlapping field of view of both eyes is 124 degrees, meaning that objects appear three-dimensional within this range. Assuming a 1.74-meter-tall person stands 1 meter away from an electronic sand table viewing a holographic image, the field of view seen by the human eye is 157 degrees, meaning that the entire screen can be seen using peripheral vision.

[0086] In summary, this invention provides an immersive holographic digital electronic sand table, comprising: an immersive display space, an immersive display system disposed within the immersive display space, and a retractable holographic projection film structure. In external projection display mode, the electronic sand table of this invention displays holographic stereoscopic images through the retractable holographic projection film structure; in internal immersive display mode, entering the space provides an immersive experience. This invention achieves the switching between holographic projection effects and an immersive experience. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0087] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
