Overview

In the digital exhibition hall, it is called projection fusion or edge fusion. Fusion is a key technology used in multi-channel display systems of more than one projector. When the projected images overlap, through the fusion software to makes it a complete picture.

Introduction

(1) Principle of fusion technology

Projection fusion technology is to overlap the edges with no gaps, brighter, larger and higher resolution. The effect of the picture is like a projector projection. When two or more projectors project a single image, some of the images overlap and the main function of the edge blending is to gradually reduce the brightness of the overlap to achieve same brightness of the entire screen.

(2) Convergence system composition

1.Screen: Make sure the screen is flat and seamless, so that the picture is perfect.

2.projector: projector directly affects the display effect; select KHD LCOS ultra-short-focus laser projector, its high lumens and high resolution ensure the stability of the display effect.

3.the fusion processor: mainly determines the content and speed of the large screen display, so the quality of the processor is significant for processing speed, clarity, soft edge fusion quality.

4. Signal processing equipment: Signal processing equipment mainly includes signal source type conversion, switching, amplification and transmission, etc., which are very important for screen display.

5. Central control system: better management on control equipment.

(3) Advantages of integration

Support for high-resolution input signals: The fuser processing is powerful enough to handle very high resolution signals while supporting user-defined signals. The traditional industrial control card splicer does not have this function.

Security and stability: the fuser has no operating system, the virus cannot be infected; full parallel work, no system overall crash risk; system data has been solidified before leaving the factory, cannot be changed, unexpected power failure will not cause data loss, the controller can withstand switch frequently.

Automatic image recognition and reconstruction: For the newly connected VGA signal, the controller can not only automatically recognize the resolution and refresh frequency of the signal, but also determine the position offset and phase error through complex calculations and automatically calibrate.

Powerful fusion processing capability: Fusion sideband processing function is mainly used to realize optical seam melting. Automatic color balance eliminates color and brightness differences between projection devices, ensuring uniform color for large screens. Single-pixel geometry correction corrects the geometry of the projected image, ensuring that the fusion controller can accommodate multiple screen configurations.

The picture is more layered: the fusion technology improves the resolution and brightness of the picture, and at the same time, with the high-quality projection screen, the layering and expressiveness of the entire display is enhanced.

Fusion technology is often used in science and technology museums, corporate pavilions, digital libraries, tourist pavilions, theme pavilions, non-legacy historical and cultural pavilions, party building museums, smart medical exhibition halls, smart city exhibition halls, historical anti-war museums, and experience halls and integrity education Hall.
