Problems solved by technology

In fact, this method cannot eliminate the influence of the physical connection seam very well, because it is difficult for light to pass through the connection seam; even if light can pass through, the light that passes through is stray. The overlap projection of the same image part of the image may easily cause some pixels to be lost at the connection seam

Embodiment 1

[0038] In this embodiment, the splicing large screen is a splicing method composed of two display units in the horizontal direction, using one circuit for image data input, and two output circuits for image data output.

[0039] See image 3 As shown, it is a schematic diagram of a hardware structure for realizing seamless splicing large-screen display in this embodiment, which includes an access module (one access circuit), a storage module, an image segmentation processing module, an image brightness adjustment module, and an output module (output circuit A, output circuit B), display module (display unit A, display unit B).

[0040] In this embodiment, the functions of the storage module, the image segmentation processing module, and the image brightness adjustment module can be realized by using FPGA (Field Programmable Gate Array, element programmable logic gate array).

[0041] Realization, wherein the storage module can be a double-chain SRAM (Static Random Access Memo...

Embodiment 2

[0058] In this embodiment, the splicing large screen is a splicing method composed of 2×2 display units. In order to avoid the blank screen of some display units due to the image acquisition speed not keeping up with the display requirements, the two displays in the first row in the horizontal direction The unit uses one access circuit A to connect to the graphics card A for image input, and the two display units in the second row in the horizontal direction use one access circuit B to connect to the graphics card B for image input.

[0059] In this embodiment, a graphics card corresponds to a row of display units, and the output image of each graphics card is processed by an FPGA and an external memory, and the two FPGAs are connected through a synchronous signal to ensure that the upper and lower rows of display units are displayed synchronously. In this embodiment, the capacity of the external memory is the size for storing 2 lines of image data.

[0060] Except for the abo...

Abstract

The invention discloses an image processing method and a device thereof for achieving seamless splicing large screen display. An image segmentation processing module segments an image into a plurality of image blocks, gap images are added to a joining edge part of each adjacent image block, and the formed images are sub-images, wherein the gap images are identical to the images of the edge part of each image block after segmentation; after brightness adjustment, each sub-image is projected to a corresponding display unit for displaying; and the gap images of each adjacent sub-image are guided into the gaps between adjacent display units by guiding optical structures in the display units so that dark lines formed at splicing gaps of the display units are brightened to truly achieve seamless splicing without causing image pixel losses, the image transition between the splicing display units is more natural and smoother, and the overall display effect is better.

Description

【Technical field】 [0001] The invention relates to the field of display screen image processing, in particular to an image processing method and device for realizing spliced ​​large-screen display. 【Background technique】 [0002] With the improvement of people's demand for display information transmission, the application fields of large-screen display have spread to various fields such as public display, transportation dispatching and commanding, weather monitoring, power and telecommunications monitoring, fire monitoring and commanding, and military commanding. [0003] Existing large-screen display technologies mainly combine multiple display units for splicing and display by stacking. [0004] The advantage of splicing large screens is that it can improve the system resolution of the display, increase the display area, realize the display of a complete picture on the entire display screen, and open windows at any position on the display screen, etc., but it also has its d...
