Problems solved by technology

[0003] However, in the current application of the background display wall, since the entire display splicing wall is spliced ​​by various DLP display units, there is inevitably a gap between the splicing display unit and the splicing display unit. Horizontally speaking, this gap can be controlled within 1 mm, but for the viewers at the TV end, they can still clearly see the larger gap between each splicing display screen. When the camera lens is zoomed in, this gap will be more obvious
[0004] In order to solve this patchwork problem, the currently adopted schemes all use the edge fusion method to form a seamless picture by performing brightness gradient and feathering on

Embodiment Construction

[0036] figure 1 shows a schematic flowchart of an embodiment of the image processing method based on the background video wall of the present invention, as figure 1 As shown, it includes the steps:

[0037] Step S101: identifying the background mosaic wall in the captured image;

[0038] Step S102: Process the captured image to eliminate the seams of the background mosaic wall in the captured image.

[0039] Among them, when identifying the background mosaic wall in the captured image in the above step S101, there may be various implementations, for example, it may be by adding a special color or a sign of nailing material to each of the four edges of the mosaic wall , or set 1 to 2 special pixel values ​​at the four corners of the screen, or add at least three prominent marks on the screen edge of the splicing display wall, so that when the camera is shooting, it can be automatically identified by recognizing these special marks The display edge of the background mosaic wa...

Abstract

The invention relates to an image processing method, a device and a system based on a background splicing wall. The method comprises the steps of recognizing the background splicing wall in photographed images; and processing the background splicing wall in the photographed images and eliminating the splicing joints of the background splicing wall in the photographed images. By adopting the technical scheme, since the display edge of the splicing wall in the images photographed by a camera is recognized and the splicing wall in the photographed images is processed to eliminate the splicing joints of the splicing wall in the photographed images, not only can the splicing joints of displayed and output pictures be effectively eliminated, but also no processing is required to be conducted to the splicing display wall, the hardware cost is not increased, the consistency of the images at different observation points can be realized and the limits caused by the change of the visual angles of the camera can be avoided.

Description

technical field [0001] The invention relates to an image processing method based on a background mosaic wall, an image processing device based on a background mosaic wall, and an image processing system based on a background mosaic wall. Background technique [0002] With the continuous development and update of LED light source DLP display technology, splicing wall display technology has been widely used. The characteristics of LED light source wide color gamut and bright colors have further deepened the application and development of DLP display technology. At present, it is more popular in the broadcasting industry. It has been used more and more, and the DLP display background wall based on LED light source is mostly used. The host can easily interact with the display background wall. After displaying the content and foreground content such as the host, it is directly output to the user for viewing. [0003] However, in the current application of the background display ...
