[0059] The following description and the accompanying drawings sufficiently illustrate specific embodiments of the present application to enable those skilled in the art to practice them.

[0060] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0061] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of systems and methods consistent with some aspects of the present application as detailed in the attached claims.

[0062] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0063] The present application provides a preset multi-screen splicing model, which is used to calculate the target observation distance required for the user to obtain the best visual effect. Therefore, when the display screen is replaced or the parameters are adjusted, the model can be used to recalculate the target observation distance required for the best visual effect as the basic parameter for content adjustment, so that the user will not suffer from visual dislocation due to angle changes, thereby improving the viewing continuity and comfort. An exemplary embodiment is used below to explain in detail.

[0064] See also Figure 1 , Figure 1 This is a system structure diagram of an interactive three-dimensional display system provided in an embodiment of the present application, the system comprising a server, a display module and an interaction device; wherein the display module is composed of a plurality of display screens and the angle between any two display screens is a preset angle, and the server is respectively communicated with the display module and the interaction device; wherein the interaction device is used to send an interaction request to the server according to the user's gesture; the server receives the interaction request sent by the interaction device, and adjusts the content displayed on the display module based on the interaction request and a preset multi-screen splicing model; the preset multi-screen splicing model is used to calculate the target observation distance required for the user to obtain the best visual effect.

[0065] Among them, the user's gesture is the way the user communicates with the display module through hand movements. These gestures can be simple (such as waving, pointing) or complex (such as a specific hand shape or sequence of movements), and are recognized by the system as interaction instructions. Interaction requests refer to requests generated by user gestures, which are recognized by the system and converted into specific operation instructions for triggering or controlling functions in the display system. The interaction device is a device for capturing user gestures, such as Leap Motion Controller or other types of gesture recognition sensors, which can detect and interpret the user's hand movements and convert these movements into electrical signals and send them to the server. Adjusting the display content is based on the user's interaction request and the multi-screen splicing model. The system will adjust the content on the display module in real time to adapt to the user's observation needs and provide the best visual experience. The target viewing distance refers to the specific distance that the user should maintain from the display screen in order to obtain the best visual effect. This distance is calculated by the multi-screen splicing model to ensure that the user can see a complete three-dimensional image without visual dislocation at this distance.

[0066] In the embodiments of the present application, on the one hand, the present application provides a preset multi-screen splicing model, which is used to calculate the target observation distance required by the user to obtain the best visual effect. Therefore, when the display screen is replaced or the parameters are adjusted, the target observation distance required for the best visual effect can be recalculated through the model as the basic parameter for content adjustment, so that the user will not suffer from visual dislocation due to angle changes, thereby improving the continuity and comfort of viewing. On the other hand, the present application adapts to the user's observation space and interaction space through gesture interaction technology. Compared with traditional interaction methods such as mouse, keyboard, and touch screen, gesture interaction provides a more natural and intuitive interaction experience, with greater flexibility and a wider range of interaction.

[0067] The interaction request carries the user's spatial location information.

[0068] In some embodiments of the present application, the specific process of adjusting the content displayed on the display module based on the interactive request and the preset multi-screen splicing model includes: calculating the real-time distance of the user relative to the display module according to the user's spatial position information; obtaining the screen parameters of the display module; calculating the shortest observation distance according to the screen parameters and the preset multi-screen splicing model; and adjusting the content displayed on the display module based on the real-time distance and the shortest observation distance.

[0069] The user's spatial location information refers to the data about the user's specific location in three-dimensional space obtained by the system through the interactive device. The real-time distance is the current distance between the user and the display module calculated by the system based on the user's spatial location information. This distance is updated in real time to reflect the user's movement. The screen parameters of the display module include technical specifications such as screen size, resolution, viewing angle, brightness, etc. These parameters have a direct impact on the display effect and user experience.

[0070] In the embodiments of the present application, the present application can ensure that users can get the best viewing experience at different positions. Real-time distance monitoring enables the system to accurately perceive changes in the user's position, and the calculation of the shortest viewing distance provides users with clear viewing guidance. Combining screen parameters and multi-screen splicing models, the system can intelligently adjust image content, whether zooming in, zooming out, or changing the viewing angle, to adapt to the user's real-time position. This method significantly improves the flexibility and adaptability of the interactive three-dimensional display system, optimizes the user's viewing experience, reduces visual discomfort caused by position changes, and makes users more comfortable and immersed when enjoying three-dimensional content.

[0071] Among them, the screen parameters include the screen width, maximum outward imaging angle and the angle between screens, and there are three display screens.

[0072] In some embodiments of the present application, according to the screen parameters and the preset multi-screen splicing model, the specific process of calculating the shortest observation distance includes: inputting the screen width, the maximum outward imaging angle and the angle between the screens of the display screen into the preset multi-screen splicing model; outputting the shortest observation distance corresponding to the screen parameters; wherein the calculation formula included in the preset multi-screen splicing model is:

[0073]

[0074] Among them, L t,min is the shortest observation distance, L s,min is the minimum distance on a single screen that satisfies the user's observation of the stereoscopic effect, Θ is the maximum outward imaging angle, and Φ is the angle between screens. The calculation process of the multi-screen imaging space to the user observation space of this calculation formula is as follows: Figure 2 As shown, the two vertically arranged solid lines are display screens, and the arc is a single-screen observation space.

[0075] In some embodiments of the present application, the specific process of adjusting the content displayed on the display module based on the real-time distance and the shortest observation distance includes: comparing the real-time distance and the shortest observation distance; when the real-time distance is less than or equal to the shortest observation distance, controlling the imaging space of the content displayed on the display module to remain unchanged; or, when the real-time distance is greater than the shortest observation distance, controlling the imaging space of the content displayed on the display module to change based on the user's gesture.

[0076] Specifically, the server's configuration parameters include CPU-Intel 12th generation i7-12700, GPU-RTX 4080, memory-32GB, multiple display screens including three X-real holographic display screens, the interactive device uses the Leap Motion Controller to realize gesture interaction, and the content displayed on the display module is three-dimensional content, which can be static content or dynamic content.

[0077] Specifically, the size of the holographic display screen is 12 cm × 16 cm and the angle between adjacent holographic display screens is 26 degrees. Static content or dynamic content is implemented based on a mainstream game engine, which is Unity3D.

[0078] In some embodiments of the present application, the specific process of calculating the real-time distance of the user relative to the display module based on the user's spatial position information includes: converting the user's spatial position information from the local coordinate system to the spatial coordinate system under the display module to obtain the converted coordinate information; calculating the Euclidean distance between the converted coordinate information and the center point of the display module; and using the Euclidean distance as the real-time distance of the user relative to the display module.

[0079] In some embodiments of the present application, the specific process of sending an interaction request to a server based on a user's gesture includes: acquiring the user's gesture image in real time; analyzing the gesture image to obtain a gesture identifier that represents the user's gesture information; determining the user's spatial position in the local coordinate system to obtain the user's spatial position information; constructing an interaction request based on the gesture identifier and the user's spatial position information; and sending the interaction request to the server.

[0080] Among them, gesture images refer to visual images of user hand movements captured by cameras or sensors. Gesture identifiers are identification information representing specific gestures obtained by analyzing gesture images, which can characterize user gestures. Local coordinate system refers to a reference coordinate system defined in an interactive system to determine the position of a user or object in space. Spatial position information refers to the specific position data of a user determined in the local coordinate system, which can be two-dimensional or three-dimensional coordinate points.

[0081] In an embodiment of the present application, by collecting the user's gesture image in real time and performing intelligent analysis, the user's gesture movements can be accurately captured and recognized and converted into specific gesture identifiers. Combined with the user's spatial position information in the local coordinate system, the system can construct accurate interaction requests that reflect the user's intentions and position status. By sending interaction requests to the server, the present application can implement an efficient and intuitive interaction method that enables users to communicate and control the system through natural gestures. This interaction method not only improves the naturalness and intuitiveness of the user experience, but also enhances the system's response speed and the accuracy of the interaction.
