Description

A 270-degree holographic projection display cabinet

technical field

The invention relates to the technical field of holographic projection, in particular to a 270-degree holographic projection display cabinet.

Background technique

3D holographic projection technology uses the principle of light interference and diffraction to record and reconstruct a three-dimensional image of an object. The recorded subjects can be objects, dynamic characters or animals. Viewers can see three-dimensional virtual characters or objects without wearing glasses. In the production process, firstly, the light wave information of the subject is recorded by using the principle of optical interference, that is, shooting; and then the light wave information of the subject is reproduced by using the principle of diffraction, that is, imaging. The holographic image is like a complex grating. Under the irradiation of coherent laser, the diffracted light wave of a linearly recorded sinusoidal hologram can generally give two images, namely the original image (also known as the initial image) and the conjugate image. The image has a strong three-dimensional effect and has a real visual effect.

With the development of science and technology and the improvement of communication audiences' appreciation and taste, when using traditional media for information release, the investment is often high, but the effect is worse. Therefore, there is an urgent need for more diverse, innovative and interactive emerging media as carriers of product and service information. Thus, the holographic projection showcase came into being.

At present, the traditional holographic projection showcase is composed of a cabinet body, a spectroscopic mirror, and a video playback device. Based on the principle of spectroscopic imaging, the three-dimensional picture is suspended in the mid-air of the real scene for imaging, creating an atmosphere that is both illusory and real. This kind of holographic projection showcase has a single function and a monotonous display method. It is mainly a one-way mode of disseminating information and has poor interaction with viewers. With the development of science now, all equipment is miniaturized and refined, but the current holographic projection showcase cannot match it, and human beings increasingly need a new display technology to solve the problem.

The infrared sensor 32 can sense the gesture of the viewer and transmit the signal to the main board 31 . The main board 31 receives the signal, analyzes and processes the data, and then projects a corresponding image through the display screen 21 . For example, when the viewer moves his hand to the left, the display screen 21 displays the previous holographic stereoscopic image; when the viewer moves his hand to the right, the display screen 21 displays the next holographic stereoscopic image. In this way, gestures are used to switch the holographic three-dimensional image, which can make the interaction between the user and the showcase more intimate, and the operation is simple and convenient.

In addition, the touch screen 113 can display detailed audio and video commentary content corresponding to the content of the holographic stereoscopic image. Operating the touch screen 113 can control the opening of the interface, changing the screen, and querying related image information, etc., to further enhance the interaction between the showcase and the viewer. For example, when a car product is displayed, the viewer can use fingers to select different modules on the touch screen 113 at will to change the color of the car, configure it, and make it translucent to show the internal structure and working principle; different internal modules can be selected. The holographic demonstration of the structure is carried out. When the engine is selected, the holographic three-dimensional image will simultaneously display the holographic display of the engine, and the internal structure and operation of the engine will be displayed one by one, so that the audience can have a deep understanding and impression of the exhibits. Since the display cabinet of the present invention has a built-in WiFi device, the touch screen 113 can also be operated to realize wireless Internet access.
