Embodiment Construction

[0056] Such as figure 1 As shown, the cross-screen image splicing control method includes a display screen group composed of several sub-screens and a drive module for the display screen group, wherein the drive module includes a data acquisition module, a data analysis module, a data simulation unit, and a data segmentation unit , a data cache module, a controller, a comparison unit, a screen control module, a display screen group, a screen analysis unit and a screen monitoring module;

[0057] Wherein, the data acquisition module is used to acquire video images to be played or spliced; the data acquisition module is used to transmit video information to the data analysis module, and the screen analysis unit is used to acquire the size information of the display screen group in real time , the size information includes the length and width information of each sub-screen in the spliced ​​display screen group, the length and width information of the display screen group, and th...

Abstract

The invention discloses a cross-screen image mosaic control method, comprising a display screen group composed of a plurality of sub-screens and a driving module of the display screen group. The invention obtains corresponding image data to be put through a data obtaining module, Then, the relevant dimensions of the display screen and the sub-screen constituting the display screen are captured bythe screen analysis unit, and the video information is projected and mapped on the virtual display interface by the data analysis module, so as to form the virtual projection video. The virtual projection video is divided into projection video streams composed of a plurality of sub-video streams according to a display screen group by a data dividing unit. Then, the projected video stream is sent to the data buffer module and the controller, and the sub-video stream of the projected video stream is displayed on the corresponding sub-screen according to the corresponding sub-screen marker by thecontroller. So that now accurate image mosaic, forming a complete picture.

Description

technical field [0001] The invention belongs to the field of image splicing, and relates to a control method, in particular to a cross-screen image splicing control method. Background technique [0002] Image stitching technology is the technology of stitching several overlapping images (which may be obtained at different times, different viewing angles or different sensors) into a large seamless high-resolution image. [0003] Image registration and image fusion are two key technologies of image stitching. Image registration is the basis of image fusion, and image registration algorithms generally require a large amount of computation, so the development of image mosaic technology largely depends on the innovation of image registration technology. The early image registration technology mainly uses point matching method, which is slow, low precision, and often requires manual selection of initial matching points, which cannot adapt to the fusion of large data volume images...
