Problems solved by technology
The effect is very good, but because the screen needs to move up and down quickly, the vibration is obvious, the height is limited, and the upward viewing angle is not ideal
[0007] Publication / announcement number: CN111583836A Publication / announcement date: 2020-08-25 This technology uses the same encircling slicing method as tree stump annual rings to divide the three-dimensional image into several concentric circles and display them separately, but is limited by the fact that each ring needs to be individually installed with LEDs Lampposts cannot get enough detailed layers within a fixed size, resulting in low precision, and adopt a one-way arrangement, because the inner lampposts are blocked by the outer lampposts, causing viewers to watch the side where the lampposts leave the direction does not display well when
[0008] Light cube technology, such as public date 2020-07-31 announcement number CN211150037U uses LED lamp beads to form a three-dimensional structure, but the light is blocked and the accuracy is limited

Embodiment
[0032] embodiments of the present invention, such as figure 2 , Taking the display cube (4) as an example, when the human eye is watching an image of 24 frames / second, the persistence of vision phenomenon can produce a sense of visual continuity, so it is set to 24 circles per second.
[0033] Set the cube size as a cube of 100mm, set the screen to be an arc with a diameter of 160mm and a length of 160mm, and a height of 160mm. figure 2 ;Set to refresh 10 frames per circle, that is, to generate a slice pattern every 36°; after calculation by the program control system, the first frame, the screen (1) displays the moment screen (1) and the cube (4) to be presented. The cut surface pattern intersecting in the warp direction is a rectangle with a height of 100mm and a length of about 108mm, such as image 3 The rectangle shown; this moment in reality, we see the pattern rendered Figure 4 as shown; when as Figure 5 After the 10 frames are all calculated by the program contr...

The invention discloses a longitude rotation slice holographic display technology. A screen, a rotation unit and a program control system are included in the longitude rotation slice holographic display technology. The screen is vertically placed, and the center line of the screen in the vertical direction coincides with the axis of the rotating unit. A three-dimensional digital model needing to be displayed is rotationally cut into a plurality of slices by a computer program control system according to the longitude direction. The program control system automatically calculates section two-dimensional images of all the slices, the program controls the rotation speed of the screen, and in the rotation process, the longitude section two-dimensional images are transmitted to the screen at the corresponding positions to be displayed in real time. A large number of different-angle section graph ghosts are mixed, so that a stereoscopic image of a displayed object is presented. The three-dimensional display device has the advantages that the structure is very simple, the cost is low, any input three-dimensional image can be displayed in a three-dimensional mode by combining computer programming, different image angles can be watched by 360 degrees, and there is no display effect difference between the left side and the right side.
Description
technical field [0001] The invention relates to a holographic display technology, in particular to a warp rotary slice holographic display technology, which is mainly used in the field of three-dimensional stereoscopic display. Background technique [0002] The meridian refers to the vertical line passing through the axis of rotation in the process of the earth's spin. This concept is used here to facilitate the understanding of the spatial relationship between the screen and the stereoscopic image. [0003] Cut surface refers to the cross-sectional pattern obtained by cutting an item by a surface. [0004] The existing holographic fans, film holograms, and pyramid-shaped four-sided holograms on the market cannot achieve true 360° viewing. [0005] Public / announcement number: CN108965848A Public / announcement date: 2018-12-07, the ultra-narrow viewing angle screen is used for rotating display. This technology can realize 360-degree viewing on the horizontal plane, but it is ...
