Embodiment Construction

[0042] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] The present invention provides a projection fusion method, referring to figure 2 , in one embodiment, the projection fusion method includes:

[0044] Step S101, performing step-by-step processing on the brightness range of the image, and initializing the fusion curve corresponding to each step of brightness;

[0045] In this embodiment, the brightness of the image includes the brightness of three components of red (R), green (G) and blue (B), and the brightness range is 0-255.

[0046] The fusion device of this embodiment provides a user interface for the user to operate. On the user interface, the brightness of 0-255 can be divided into several segments, and each segment point is a first order. For example, the image brightness is divided into three levels of brightness: RGB0 (R=0, G=0, B=0), RGB 128 (R=128...

Abstract

The invention discloses a projection fusion method and device. The projection fusion method includes the following steps that order division processing is conducted on the brightness range of images, and fusion curves corresponding to brightness on all orders are initialized; the brightness of each pixel of the images input at the front end is acquired, and the fusion curves corresponding to brightness on two orders adjacent to the brightness of each pixel are selected; the images are fused according to the brightness of the pixels and the selected fusion curves; the fused images are output to a projector. Smooth transition of all color orders can be comprehensively achieved in the projection fusion process, the colors of the images output by projections are kept consistent, and brightness is uniform.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a projection fusion method and fusion equipment. Background technique [0002] Projection fusion is to overlap the edges of the pictures projected by a group of projectors, and display a bright picture without gaps through fusion technology. When multiple projectors combine to project a picture, some of the images will overlap. The main function of fusion is to gradually reduce the brightness of the overlapping parts of the image so that the brightness of the entire picture is consistent. [0003] like figure 1 As shown, the projection fusion system includes multiple video sources, a fusion device, multiple projectors and display screens. In the prior art, the fusion device lowers the image brightness of the overlapping area to reduce the brightness value of the overlapping area of ​​the projector, so as to achieve the purpose of consistent color and uniform br...
