Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0038] An image ratio edge fusion projection method of an embodiment, comprising:

[0039] The image divider divides the image into several regular graphics, and the several regular graphics are respectively projected by different image projection devices; wherein, the edges of the adjacent graphics divided into several regular graphics overlap each other, and the graphics simultaneously appear in the adjacent graphics after division. Edge; arrange criss-crossing vertical lines and horizontal lines on the entire image; different image projection devices project several divided regular graphics, and adjust the image projection device so that the edges of adjacent graphics overlap the vertical lines and horizontal lines in the graphics Completely overlap, so that the image content of the overlapping part is e...

Abstract

The invention discloses a projector image edge fusion system and method, and relates an image edge fusion processing for fusing multiple pictures in the field of projector devices. The system comprises an image segmentation processing module used for performing equal division processing on images; a color consistency processing module used for adjusting the colors of more than two images to be consistent; an image uniformity adjustment module used for adjusting the brightness and color uniformity of the images; a fusion tape processing module used for performing image cutting and gradual imagebrightness change processing on fusion tapes between more than two images; a dark field brightness repair processing module used for adjusting the brightness of a non-overlapping areas under dark field conditions to make it consistent with the brightness of an overlapping area. In the projector image edge fusion system and method disclosed by the invention, the dark field problem in the fusion isperfectly solved by the dark field brightness repair processing module, and the fusion band brightness and the smoothness of the colors can be well achieved through the fusion band processing module,so that the details of the picture can be further improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image edge fusion processing system and method for merging multiple pictures in the field of projector equipment. Background technique [0002] Existing large-frame projection methods usually adopt the following three methods: the first is to use a single high-power projector to project a complete image on a large screen, but this method generally requires a huge Throw distance and space requirements. In addition, due to the limited resolution of the projection equipment, when the image is enlarged, the edge of the image will appear jagged, and the picture will appear as rough as the LED display, which will reduce the image accuracy and affect the final projection effect. The second is the optical splicing method, that is, using multiple projectors to project optical images on a single large screen, and each projected image is connected with each other to form a comp...
