Method and device for eliminating splicing seams of splicing wall as well as image system based on splicing wall

Abstract

The invention provides a method and a device for eliminating splicing seams of a splicing wall as well as an image system based on the splicing wall. The method comprises the following steps: distinguishing a background splicing wall in a shot image; processing the shot image, and eliminating the splicing seams of the splicing wall in the shot image. According to the technical scheme of the invention, show edges of the splicing wall can be distinguished in the image shot by a camera, and the splicing wall in the shot image can be processed to eliminate the splicing seams of the splicing wall in the shot image, thus the splicing seams of a picture output by the display can be effectively eliminated, but the splicing display wall does not need to be processed, the hardware cost can not be increased, and the consistency of pictures with different viewpoints can be realized without the restriction of the viewing angle changes of the camera.

Description

technical field [0001] The invention relates to a method for eliminating seams of a mosaic wall, a device for eliminating seams of a mosaic wall, and an image system based on a 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 wall, since the entire display splicing wall is ...

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 the overlapping area pictures between the two projectors. The fusion method must use the overlapping area of ​​the output of the two display units, but this processing method destroys the sealing of the optical path of the box-type display unit, and is not suitable for the application of eliminating seams on display background walls such as DLP and LCD

On the other hand, at the recording site of radio and television programs, there will be multiple shooting points, and different shooting points will still cause the uniformity of the picture, and there will also be situations where the background wall is not frontally shot, which will affect the visual effect of TV viewers
