Integration of multi-channel surround screen display system Overview: In recent years, with the continuous development and innovation projection display technology, the edge-blending technology is rapidly popular support wide-screen projection display area. Below is a typical multi-channel seamless projection system, three projectors are used to display the contents of the projection on the same wide-screen, produce a high-resolution, field of continuous, seamless, consistent brightness and color image. Establish such a seamless widescreen projection system, the work needs to be done at least the following two aspects: 1, the fusion zone feathering, correction processing. Because the fusion zone is the result of two projectors interaction, the brightness non-fused 2-fold part, so to be feathered, so that the brightness of the fusion zone is maintained with consistent brightness non-fusion zone; at the same time, the projector must be accurately The position correction, otherwise a straight line through the fusion zone during fatally straight. 2, for example, non-planar screen or a spherical screen, a cylindrical screen, the need for distortion correction surface. All projectors are designed for flat screen, when the projector so that the image is projected onto the dome or dome like curved screen, the image will be deformed distortion, a phenomenon known as nonlinear distortion. In order to get the correct image on the curved, spherical screen display, the image must be processed, this processing is called non-linear distortion correction. ? My company after years of efforts, the introduction of the surface with a high cost performance Vis3D- correction fusion machines, the fusion machine has been tested in a multi-channel post-screen projection works, the effect is very satisfactory. 2011 New Vis3D XGA multimedia convergence machine calibration curve
