Splicing and fusing method applied to display large-sized images

Abstract

The invention discloses a splicing and fusing method applied to display large-sized images, comprising the following steps: setting a projection overlapping region size value between adjacent projection images; segmenting the images in each frame based on a pixel and according to the number, resolution ratio and projection overlapping region size values of projectors; setting the sensitivity weight values of color channels of red, green and blue of each projector; calculating the boundary distance from each pixel point in each image to the boundary of the image; calculating the color weight value of each pixel point according to the boundary distance and the projection overlapping region size value; and respectively multiplying the color values of red, green and blue of each pixel point in the image overlapping region by the color weight value of each pixel point, so as to acquire the color values of actual pixel points; and simultaneously projecting and displaying. By utilizing the method provided by the invention, the defects of image overlapping region display in the existing projection technique of multiple projectors are overcome, and the smooth transition of the images of the multiple projectors on the overlapping region is realized, thus greatly providing the overall visual effect of pictures.

Description

technical field [0001] The invention relates to a projector image display method, in particular to a splicing fusion method applied to large-scale image display. Background technique [0002] High-resolution, high-brightness large-screen displays are more and more widely used in scientific computing visualization, industrial design, virtual manufacturing, military simulation, entertainment and other fields. Currently widely used large-screen display systems either use large-screen display walls or high-performance projectors, which are very expensive. Therefore, a high-resolution large-screen display system that uses multiple projector arrays for seamless splicing is becoming more and more popular. [0003] The system structure diagram of multi-projector mosaic display is as follows: Figure 1-2 As shown, the splicing of the projector array composed of multiple projectors can realize the display of the screen, and the seamless splicing of the projection array composed of fo...

AI Technical Summary

Problems solved by technology

This method is simple to implement and requires less calculation; however, it is difficult to install the hardware, and it is difficult to install it in a seamless state. There will be obvious splicing gaps at the connecting part of the two projectors;

[0006] (2) Simple overlap: that is, the images of the two projectors partially overlap, but there is no attenuation of color and brightness

This method is simple to implement and requires less calculation. Although there will be no gaps in the overlapping parts of the projection area, the superimposed area is obviously brighter than other non-superimposed areas, which affects normal viewing.
