Embodiment 1

[0047] The first embodiment is based on the fact that the position of the user and the reference screen is relatively fixed, and the angle between the reference screen and the reference screen is obtained to realize the adjustment and display of the image adapted to the angle of the viewpoint.

[0048] First, set the display screen directly in front of the user as the reference screen, and the rest as reference screens, obtain the angle between each reference screen and the reference screen, and send the angle to the controller; then, when there is an image to be displayed on a reference screen During the upload, the controller uses the obtained reference screen and the angle of the reference screen to transform the image; finally, the transformed image is transmitted to the display screen for display.

[0049] figure 2 It is a schematic diagram of a multi-screen display scene in the present invention, in which the display screen 202 is located directly in front of the user as a re...

Embodiment 2

[0061] Unlike the first embodiment, which obtains the angle between the reference screen and the reference screen, this embodiment directly obtains the angle between the user and the display screen; the controller makes adaptive adjustments to the image to be displayed according to the angle between the reference screen and the user. To ensure the display effect.

[0062] Such as Figure 4 As shown, the display screen 401 and the display screen 402 are placed in front of the user at a certain angle. Since the two are similar in relative positions and angles to the user, the user is directly used as the angle reference; the coordinate axes x and y are based on the user. The benchmarks respectively represent the connection direction on both sides of the user and the direction from the body to the head. If the user is standing or sitting upright, he can know that his default coordinates are (0, 0). It can be obtained that the display screen 401 and the x-axis are 225°, and the displ...

Embodiment 3

[0066] The above embodiment 1 and embodiment 2 both describe the display screen extending in the horizontal direction, and the present invention is also applicable to the multi-screen display extending in the vertical direction.

[0067] Such as Figure 5 As shown, it includes a display screen 502 as a reference screen, and display screens 501 and 503 on both sides thereof, and a display screen 504 on the upper side. For this kind of multi-screen display, the display screens 501 and 503 on both sides adopt the method described above, and the method for adjusting the image of the display screen 504 is similar to this, except that when determining the angle relationship with the reference screen or the user , Is determined by the angle on the y-axis. The angle between the display screen 504 and the display screen 502 on the y-axis is 45°, and they coincide in the x-axis direction. Other steps are similar to Embodiment 1 or Embodiment 2, and will not be repeated here.

[0068] For d...

Abstract

The invention discloses a multi-screen display method, comprising the following steps: a controller obtains the viewpoint angles of various display screens and users; an image is transformed accordingto the viewpoint angles, and the transformed images are sent to display screens corresponding to the viewpoint angle to be displayed. The invention has the advantages that: by transforming the imageadapting to various viewpoint angles, the transformed images are transmitted to the display screens to be displayed to users, so the displayed images of various display screens are ensured to be closer to the visual angle of users, and the images are more real; the problem of non-ideal display effect caused by viewpoint angles are effectively solved; the invention has vivid and distinctive displayeffect for three-dimensional display particularly; the invention can be embodied by arranging the angle sensors with low price, and no other hardware equipments need to be added, so the invention iseconomical and practical; meanwhile no extra operation needs to be performed by users, and the invention is very convenient. The invention also discloses a multi-screen display system.

Description

Technical field [0001] The invention relates to the technical field of graphics processing and multi-screen display, in particular to a multi-screen display method and system. Background technique [0002] When people watch the image on the display screen, they hope to obtain a broad visual effect. One way is to increase the size of a single display screen, which increases the price of the display screen, and the huge display screen is not conducive to moving and carrying, especially for LCD (Liquid Crystal Display, liquid crystal display) screens. , It is difficult to achieve from a technical point of view; another approach is to use multi-screen display, this method is becoming more and more common, can bring users a broad field of vision and more display content, and the active connection between the various displays, Can be folded and carried, very convenient. [0003] In the current multi-screen display, it is mainly used in two aspects: [0004] One is that each display scre...
