Weak current College】 【seamless splicing technology development and theory overview.

With display technology and control technology for continuous integration and development, in the high-end engineering field, by concatenation of the large-screen image display has been widely used, its large screen and multi-screen display and clear, lifelike appearance makes monitoring, security, conferences, simulation, and other areas of work efficiency is greatly improved, while at the same time contributing to the technical level of the industry's rapid progress.
In a mosaic-based display and control technology for seamless integration of images to display in seamless splicing technology is one of the important technologies.
In recent years, as software and hardware technology, seamless splicing technology into a very mature stage, and has been widely used in command and control, virtual simulation and training, industrial manufacturing, design, scientific research and complex decision-making process, in exhibitions, Visual Entertainment, advertising, and other areas of application are also becoming more common.
Is it sew concatenation technology is a special, requires relatively high projection display application, you can implement a multi-screen image fusion, and set the concatenation of gap reduced to a minimum so that the complete heavy match of splicing technology. Is it sew concatenation technology not only need to complete hefty screen, Super projections that the super-size screen projection also have special requirements.
At present, through the built-in seamless splicing technology, high-end projectors or through external to sew the concatenation processor may implement super sharp pictures of seamless integration.
Is it sew concatenation technology development has experienced a pure hardware integration technology, pure software and hardware integration technology and Synergistics three phases.
Pure hardware integration technology through optical shading to fusion image, pure software Fusion is handled via electronic lines to complete the image fusion, hardware integration technology mean both optics fusion processing and electronic fusion.
Because hardware integration can better handle the fusion image of black balance software fusion can better deal with the white balance of the image, the combination of both hardware and software integration technology will be able to compare the perfect realization of partial color image fusion of emergence.
From Mosaic effect, seamless splicing technology has undergone three phases: hard-edged splicing, overlaps splicing and soft edge Fusion splicing.
Hard-edged splicing is clearly split lines (i.e. physical slot), a panoramic view of integration cannot be achieved; overlap concatenation displayed refers to two projectors cast out of the Office of the flattener to image superimposed overlap, but this kind of concatenation obvious flatten Office as brightness overlay, there were light areas of the ills that affect implementation of seamless effect.
Soft edge Fusion splicing through edge integration technology of processing, which implements the full integration of both sides, and eliminate overlaps splicing caused too light areas and soft edge Fusion splicing can adapt to the plane, cylinder, sphere, etc. all kinds of surfaces in the shape of the mosaic, have broader applicability.
