Description
Technical Field
The invention belongs to the field of holographic technical equipment, and relates to a holographic display device.
Background
Holographic imaging, also known as virtual imaging, is a technique for recording and reconstructing a true three-dimensional image of an object using the principles of interference and diffraction. The holographic imaging system suspends the three-dimensional picture in the half air of the real scene, and a user can observe virtual imaging from the outside of the holographic projection device, so that the holographic projection device has wide attention in the aspect of three-dimensional display of a virtual object due to unique sense of scarcity.
In the existing holographic imaging technology, a holographic display device based on reflection and transmission of an imaging film is mainly a holographic imaging frame composed of four transparent films, the holographic imaging frame is placed above or below a display screen, a video image is played on the display screen, and the video image is reflected and projected onto the holographic imaging frame to form a holographic imaging visual effect, so that a user can observe images from four sides of the holographic imaging frame, and accordingly, the user can see a volitional virtual object. The device has low cost and simple manufacture, images are in the space of the holographic imaging frame, and the device has excellent three-dimensional display effect.
However, the conventional holographic display device based on the imaging film can only display a single-layer holographic image, and although the sense of elegance is strong, the sense of depth is still deficient.
Disclosure of Invention
In order to overcome the problems of the current holographic display device, the invention provides a double-imaging hybrid holographic display device, which is added with second-time holographic imaging on the basis of the existing holographic imaging device based on an imaging film. The second imaging is superposed on the first holographic imaging, so that the effect of double-imaging superposition mixed display is presented, the depth of the picture is improved, and the practicability and the interactivity are better.
The method for solving the main technical problem of the invention is to add a display screen to the holographic display device based on the projection film, and the display screen and the prior display screen realize the synchronous projection of double screens one above the other, thereby achieving the mixed effect of double images.
The device comprises a top display screen, a bottom display screen and a holographic imaging frame. Four isosceles trapezoid transparent films with the same shape and size are symmetrically combined into a quadrangular frustum pyramid-shaped holographic imaging frame which is arranged in a large-size mode and a small-size mode, and each transparent film forms an angle of 45 degrees with the horizontal plane. The top display screen is square and arranged above the holographic imaging frame, the display surface is placed downwards, and four edges of the top display screen are connected with four edges of the top of the holographic imaging frame. The bottom display screen is also square and is placed at the bottom of the holographic imaging frame, the display surface is placed upwards, and the center of the bottom of the holographic imaging frame is aligned with the center of the bottom of the holographic imaging frame. The top display screen is divided into 4 regions by two diagonal lines, the number of reverse time needles from the front side is marked as regions A1, B1, C1 and D1 respectively, the bottom display screen is divided into 4 regions by two diagonal lines, and the number of reverse time needles from the front side is marked as regions A2, B2, C2 and D2 respectively. The regions A1, B1, C1 and D1 correspond to the regions A2, B2, C2 and D2 in sequence in the vertical direction. The outer side surface of any isosceles trapezoid transparent film is an overlapping playing area of a video played by the near-end area of the bottom display screen reflected by the near-end isosceles trapezoid transparent film and a video played by the far-end area of the top display screen reflected by the far-end isosceles trapezoid transparent film.
When the double-imaging holographic display device is used, the top display screen plays a video, and a video image is reflected by the holographic imaging frame to generate a holographic image in the holographic imaging frame; and simultaneously, the bottom display screen also plays a video, the video image is reflected by the holographic imaging frame, a holographic image is also generated in the holographic imaging frame, and the video image is overlapped and mixed with the original holographic image to form a new holographic image. The user can observe the holographic imaging frame from four angles including front, back, left and right: on the right side of the holographic imaging frame, a user sees a holographic image formed by reflecting the image in the D1 area through the left side of the holographic imaging frame, and simultaneously sees a holographic image formed by reflecting the image in the B2 area through the right side of the holographic imaging frame, and the image received by the user is the superposition of the two layers of holographic images; similarly, in front of the holographic imaging frame, the user can see that the picture of the screen area a2 is superimposed on the picture of the screen area C1, on the left of the holographic imaging frame; the user can see that the picture of the screen area D2 is superimposed on the picture of the screen area B1; behind the holographic imaging frame, the user can see the picture of screen area C2 superimposed on the picture of screen area a 1.
