Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] like figure 1 Shown is the overall structure diagram of the technology of the present invention.

[0041] In the embodiment of the present invention, two graphics cards are used for splicing. An embodiment of the present invention is a two-way ultra-high resolution heterogeneous image mosaic system, including two graphics cards and a splicing controller connected to the two graphics cards, and the splicing controller inputs the pixels of the images simultaneously generated by the two graphics cards Stream 1 and pixel input stream 2 are spliced ​​and sent to the frame buffer module, and then the output pixel stream is sent to the user port.

[0042] like figure 2 Shown is a logical architecture diagram of the splicing controller in the embodiment of the present invention.

[0043] The splicing controller includes a rate det...

Abstract

The invention relates to the technical field of image mosaicing, in particular to a method for mosaicing heterogeneous images and a system thereof. The method for mosaicing the heterogeneous images comprises the steps of mosaicing more than one pixel input stream, firstly saving each pixel input stream into a frame cache module, mosaicing each frame of data in a cache sub-module through a mosaicing device and sending to a user port, and the method further comprises the following steps: (1) detecting more than one pixel input stream of images generated by a display card, and determining the pixel input stream with slowest rate; (2) carrying out processing of reducing frame rate on the multiple pixel input streams according to information of the pixel input stream with the slowest rate, and getting multiple pixel input streams after frame-reducing processing; and (3) mosaicing the multiple pixel input streams after the frame-reducing processing, getting image data after mosaicing and frame-reducing processing and sending to the user port. By adopting the invention, the phenomena of screen flicker, instantaneous screen noise and the like during the mosaicing caused by inconsistent frame rates among the multiple pixel input streams can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of image splicing, in particular to a heterogeneous image splicing method and system thereof. Background technique [0002] In the multi-screen display system in the video field, it is usually necessary to display a complete computer desktop image with high resolution and high refresh rate on multiple display screens, and there are mainly two technical routes for the generation of the high-resolution image: one One is that a computer integrates a high-resolution graphics card, and the high-resolution graphics card generates the high-resolution image; the other is that a computer integrates multiple high-resolution graphics cards, and each graphics card simultaneously generates high-resolution images. High-resolution images, by connecting an external stitching instrument, a larger high-resolution image is produced. [0003] Among them, in the first solution, when outputting a high-resolution image, due t...
