When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of systems and methods consistent with certain aspects of the utility model, as detailed in the appended claims.

As shown in fig. 1, a holographic imaging system, comprising: the display screen comprises a rectangular frame 1, a first display screen 3, a planar structure 4 and a second display screen 5;

the rectangular frame 1 is arranged at a preset inclination angle with the ground, and a holographic film 2 is fixed on the rectangular frame; the holographic film 2 is a film with a special chemical layer. The high-reflectivity film has high reflectivity, can be used for reflecting images, and has high transparency.

The first display screen 3 is arranged on the first side of the rectangular frame 1, is perpendicular to the ground, and is used for displaying foreground pictures;

the planar structure 4 is arranged on the second side of the rectangular frame 1, and comprises a first plane a, a second plane B and a third plane C, wherein the first plane a, the second plane B and the third plane C are sequentially connected together at a preset angle, and the third plane C is connected with the bottom end of the rectangular frame 1;

and the second display screen 5 is arranged on the second plane B and is used for displaying a background picture.

As shown in fig. 2, in one embodiment, preferably, an included angle between the first plane a and the second plane B is ≦ C, the angle C is 90 ° an included angle between an auxiliary plane D connected to an upper edge of the first plane a and a lower edge of the third plane C and the rectangular frame 1 is ≦ B, the included angle between the rectangular frame 1 and the first display screen 3 is ≦ B ', the included angle between the auxiliary plane D and the third plane C is ≦ a, the angle a is 90 ° — -B- ≦ B' × 90 ° -2 ≦ B, the auxiliary plane D is parallel to the second plane B, the included angle between the second plane B and the third plane C is D, and the angle D — 180 ° a.

In one embodiment, preferably, the length of the first plane a is (length of the auxiliary plane D-length of the second plane) × tan ×.a.

In one embodiment, preferably, the length of the third plane C is (length of the auxiliary plane D-length of the second plane)/cos & lt a.

In one embodiment, the length of the second plane B is preferably equal to half the length of the auxiliary surface D.

In this embodiment, as shown in fig. 2, the included angle formed between the rectangular frame 1 and the LED display screen 3 is ≧ b'. Below the holographic film 2 there is a planar structure 4. Because of the reflection of the planar structure 4 by the holographic film 2, a virtual image identical to the planar structure 4 appears at the location mirrored at the other side of the holographic film 2. Therefore, when the included angle ═ b' between the planar structure 4 and the frame 1, the auxiliary surface D of the planar structure 4 completely coincides with the display screen 3. As shown in fig. 3 and fig. 4, if b < b', the reflected virtual image plane structure 4 is inclined forward and the auxiliary surface D cannot be superimposed with the display screen 3. If < b > b', the reflected virtual image plane structure 4 will tilt backwards, and the auxiliary surface D cannot be overlapped with the display screen 3. Therefore, the technical scheme can only present an ideal display effect when the < b > is equal to the < b'.

The plane structure 4 is formed by connecting A, B, C three equal-width planes together at a certain angle, and an included angle c between the plane A and the plane B is 90 degrees; plane B is parallel to auxiliary plane D; since plane B is parallel to auxiliary plane D.

Since plane B/subsidiary surface D, the length of a ″, subsidiary surface D, A ″, is the length of a. As can be seen from the trigonometric function, the length of plane a is equal to the length of plane a ═ tan × (the length of plane D — the length of plane B). sin & lt a & gt E/length of auxiliary surface D; the length of plane C is (length of plane D-length of plane B)/cos a. The length of the plane B is typically half the length of the auxiliary surface D in view of visual effect. An LED display screen 5 is mounted on the plane B.

The following illustrates how the dimensions of the various parts of the holographic structure can be derived from the above formula.

It is assumed that it is desirable to design a holographic receptionist's station that can display a virtual receptionist's image through the structure. The height of the display screen 3 is set to 2.2 m from the viewpoint of completely displaying the normal actions such as the height of a normal person and waving his hand, so that the length of the auxiliary surface D of the planar structure 4 is also set to 2.2 m. The height E of the planar structure 4 is typically between 1 meter and 1.1 meters, set to 1.1 meters, with reference to the height of a conventional reception desk. Therefore, sin < a > is equal to 1.1/2.2 equal to 0.5 equal to the height E of the planar structure 4/the height of the auxiliary surface D. The angle a is equal to 30 degrees, and 2-angle b is equal to 90 degrees-angle a is equal to 60 degrees. The angle b is equal to 30 degrees. The height of the display screen 5 is half of the height of the auxiliary surface D in view of the overall visual sense of the background, and the length of the plane B is 1.1 m, which is the height of the display screen 5. Therefore, the length of the plane a (length of the auxiliary plane D-length of the plane B) × tan ═ 1.1 m × 0.5773 ═ 0.635 m. Therefore, the length of the plane C (the length of the auxiliary plane D-the length of the plane B)/cos & lt a is 1.27 meters.

As shown in fig. 5 and 6, in one embodiment, preferably, two sides of the rectangular frame are clamped by a first clamping plate 6, a second clamping plate 7, a third clamping plate 6 'and a fourth clamping plate 67', and connected with the first display screen and the planar structure.

In one embodiment, preferably, the system further comprises: and a top sealing plate 8, wherein the top sealing plate 8 is connected between the top of the first display screen 3 and the top of the rectangular frame 1 so as to seal the top.

Therefore, the whole holographic structure is sealed from the side face and the top, the holographic visual display effect can be watched through only one window in the front face, the light intensity entering the holographic structure is limited, and a better visual effect can be presented.

The display screen 3 behind the holographic film is responsible for displaying the foreground picture. The background screen displays an image via the display screen 5, the light of which, as well as the light reflected by the space formed by the structures 4, is incident on the holographic film 2, so that a virtual image is formed from the light reflected from the holographic film 2, which virtual image appears to be located behind the holographic film 2. Thus, a stereoscopic space with strong depth is formed behind the display screen 3, and the background image displayed by the display screen 5 and the foreground image displayed by the display screen 3 generate obvious depth feeling. Therefore, people neglect the display screen 3 in front of eyes, and the naked-eye 3D stereoscopic image display effect is presented in the whole system.

Compared with the current system, the technical scheme of the utility model has the advantages of no need of a settled ground space and low requirement on the space.
