Description

Technical Field

[0001] The present invention relates to the field of optical imaging technology, and in particular to a holographic display system based on artificial intelligence. Background Art

[0002] Holographic display is a high-tech device that uses holographic technology to display three-dimensional images. It can present the three-dimensional image of an object in a holographic form, providing a three-dimensional visual experience that can be viewed without wearing any auxiliary equipment (such as 3D glasses).

[0003] In the prior art, light reflection is usually used to present video content using transparent materials, but this method cannot appreciate the complete three-dimensional effect from all angles. In another prior art, a holographic display with a stronger sense of three-dimensionality is achieved by controlling the light points of a fast-moving light source, but this method will generate greater noise and higher safety risks, and due to its defects such as a limited number of control modes, large pixel size, and discrete phase modulation, it leads to lower clarity.

[0004] Therefore, a high-resolution holographic display system is urgently needed. Summary of the invention

[0005] The purpose of the present invention is to provide a holographic display system based on artificial intelligence to solve the above problems.

[0008] The display module comprises a planar holographic unit and a stereoscopic holographic unit, wherein the stereoscopic holographic unit is inside the planar holographic unit;

[0009] The artificial intelligence control module uses a deep learning algorithm to make the transmission image of the planar holographic unit completely overlap with the projection of the stereoscopic image in the stereoscopic holographic unit on the plane where the planar holographic unit is located.

[0010] The display module is located in the safety protection module;

[0011] The noise reduction module is located in the stereoscopic holographic unit.

[0012] The present invention realizes the intelligence and safety of the holographic display system by setting a display module, an artificial intelligence control module, a safety protection module and a noise reduction module. The combination of the planar holographic unit and the stereoscopic holographic unit of the display module makes the image display more three-dimensional and vivid. The artificial intelligence control module ensures the precise overlap of the image through a deep learning algorithm, thereby improving the accuracy and realism of the display effect. The setting of the safety protection module enhances the stability and safety of the system. The integration of the noise reduction module effectively reduces the noise during system operation and improves the user experience.

[0014] The rotating unit comprises a mounting member, a driving motor, a transmission assembly and an annular track. The driving motor and the transmission assembly are both mounted and fixed below the mounting member. The driving motor is mounted on the annular track through the transmission assembly. The transmission assembly transmits the power of the driving motor to the annular track, so that the driving motor and the transmission assembly move on the annular track. The annular track is mounted and fixed on the mounting platform. The planar holographic unit is mounted and fixed on the mounting member.

[0016] The present invention improves the flexibility and dynamic display capability of the system by adding a mounting platform and a rotating unit. The fixed installation of the planar holographic unit and the design of the rotating unit enable the planar holographic unit to make up for the problem of low definition of the stereoscopic holographic image and adapt to different display requirements. The integration of the drive motor and the transmission assembly realizes precise power transmission and control, and ensures the stability and smoothness of the image display.

The artificial intelligence control module identifies the position of the eyes in the image and, after calculation, sends control signals to the rotating unit, the flipping unit and the lifting unit, so that the light reflected by the reflective glass coincides with the direct projection light of the stereoscopic holographic unit to the eyes.

[0022] The present invention realizes real-time recognition and tracking of the viewer's eye position by setting a camera assembly on the side of the luminous screen. The artificial intelligence control module dynamically adjusts the reflected light and the direct projection light according to the eye position information to ensure the accurate overlap of the image with the viewer's line of sight, thus improving the viewing effect and immersion of the holographic image.

The image recognition unit processes the real-time video taken by the camera component, recognizes the eyes and the height information of the eyes and the center position of the eyes relative to the stereoscopic holographic unit in real time, and then sends the height information of the eyes and the center position of the eyes relative to the stereoscopic holographic unit to the signal control unit and the projection generation unit. The signal control unit generates driving signals for its corresponding rotation unit, flipping unit and lifting unit, and the projection generation unit displays the projection picture of this position on its corresponding luminous screen in real time.

[0026] The present invention improves the intelligence level of the system by refining the functions of the artificial intelligence control module. The division of labor and cooperation among the image recognition unit, the signal control unit and the projection generation unit realizes the precise control and real-time display of the holographic image, and improves the accuracy and response speed of the display effect.

The installation positions of the upper permanent magnet follower and the lower permanent magnet follower correspond to the stroke required for the vertical moving component. The controller is electrically connected to the upward electromagnetic driving component and the downward electromagnetic driving component, respectively, to control their electromagnetic strength and direction.

[0030] The present invention uses electromagnetic drive. When the three-dimensional holographic unit is in use, the up and down travel speed of its surface light source panel can reach up to 300 times per second. The prior art uses spring components for driving, which makes it very noisy. However, the present application uses electromagnetic drive to achieve contactless transmission, reduce the noise generated during contact, and enhance the display effect.

[0034] The present invention improves the safety and comfort of the system through the integrated design of the safety protection module and the noise reduction module. The double protection of the outer glass and the inner glass, as well as the filling of the refractive liquid, not only enhances the protection capability of the system, but also effectively reduces the noise while ensuring the clarity, providing users with a safe and quiet viewing environment.

[0035] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0036] The present invention significantly improves the display effect and user experience of holographic images. The core of the system lies in the artificial intelligence control module, which accurately controls the image overlap of the planar holographic unit and the stereoscopic holographic unit through a deep learning algorithm to ensure the accuracy and realism of the image display. The integration of the safety protection module and the noise reduction module not only enhances the stability and safety of the system, but also effectively reduces the operating noise, providing users with a more comfortable viewing environment. The dynamic adjustment capability of the system is enhanced by the design of the rotating unit, the flipping unit and the lifting unit, so that the holographic image can be adjusted in real time according to the position and viewing angle of the audience, improving the adaptability and interactivity of the image display. The introduction of the camera assembly realizes the real-time recognition and tracking of the audience's eye position, further enhancing the viewing effect and immersion of the holographic image. In addition, the scalability and flexibility of the system are improved by adding multiple mounting parts, drive motors, transmission components, planar holographic units and flipping units to adapt to the display requirements of different scales and complexities.
