【 Weak current College 】 large screen projection is it sew concatenation technology---Power By 【 China power house network 】

Large screen projection is it sew concatenation technology already from the initial virtual simulation and virtual reality applications has been extended widely to command and control, virtual simulation and training, industrial manufacturing and design as well as scientific research and complex decision-making process, and in the exhibition, advertising, entertainment and more prevalent in the field of application. After the industry manufacturers for many years technology development and efforts to present a seamless splicing technology has been developed to a very mature stage. Due to the large screen is it sew concatenation performance requirements are applied in very high places of special application, for the equipment of high reliability requirements are high, so high for large screen not sewing the concatenation projector procurement in will not be able to mix business with pleasure to the other for education, entertainment and other aspects of commercial projector, its specification have more stringent requirements


Big screen seamless splicing 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 multi-screen technology. Big screen seamless splicing 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. Built-in seamless splicing technology, high-end projector main branch as ChristieMatrixS + 2K, Christie highlighted projector DS + 60, BARCORLMG5 "performer" projector, 3Dperception Visual SX25 + projector, Panasonic PT-DW7000E, etc. (details refer to: applied to big-screen mosaic of high-end professional projector recommended); external to sew the concatenation processor mainly Norway 3Dperception integration build controller, depending on the (Christie) edge fusion processor Imager.

Big screen seamless splicing 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 large-splicing 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. Soft edge Fusion splicing technology is now mainstream technology, it is the future direction of development.
