Three-channel projection splicing solution analysis
[Zhongguancun online projector channel original] The large screen Qingming Shanghe map displayed at the Beijing Olympic Games. At the Shanghai World Expo, the Hunan Pavilion Magic Bishua ring realized by projector splicing has left a deep impression on many visitors. The technology is developing, the technology is updating, and the projection splicing display can not only realize the splicing of the flat display picture, but also the curved and irregular spherical display effect can be realized. Today, let's share how the 160-degree arc stitching solution provided by the next four-dimensional scene is realized.
In the scheme, three 6200 lumens NEC NP4100+ engineering projectors are used, each of which forms a channel to generate a three-channel mosaic display effect in a horizontally spanning manner, and three VGA computer signals provide display content support. The hardware nonlinear geometric correction technology is used between the projectors of adjacent channels to form a seamless mosaic widescreen projection display system with a 160 degree circular metal projection hard screen.

The overall implementation has the following characteristics:
â– Super-realistic display of wide-screen ring screen
â– High quality dlp projector
â– High brightness gain curved hard metal curtain
â– Full hardware system implementation
â– Fast processing speed
â– Strong immersion and visual impact
â– Hardware Surface Correction Technology
â– Multi-screen processing switching of multiple inputs
Three NEC NP4100+ projectors can achieve a resolution of 3072×768 after theoretical splicing, but in the splicing, the proportion of the fusion band needs to be reduced. This solution can achieve 2500×768 ultra-widescreen clear demonstration effect.
How to configure the hardware device
The splicing of the device is for soft content, and this is not a one-time solution. Therefore, it is necessary to consider the upgrade and maintenance cost of the system for the user in the future. It is recommended in this solution not to consider expensive projectors with built-in adjustments, but to recommend products like NEC NP4100+ engineering projectors.
Three-channel curved cinema splicing system
The image processor adopts the self-developed products of Siwei Lijing and has independent intellectual property rights. Easy adjustment, true fusion effect, completely seamless, support for high resolution, high refresh rate, high compatibility and other features.
The four-dimensional image processor features are as follows:
☆ 16-node fast surface adjustment, 15 minute adjustment surface correction
☆ The fusion effect is first-class, the human eye is completely seamless and no color difference, and the fusion band is partially clear.
☆ Suitable for most high-brightness projections to make large-screen (stereo) display systems, greatly reducing the requirements for engineering projection
☆ Ultra-high refresh rate (60~120 Hz optional), can be used for real-time simulation display and playback action blockbuster
☆ Hardware surface correction and edge fusion, no compatibility restrictions
☆ There is no limit to the size of the edge blending overlap area.
☆ Correction of the geometry of each channel, independent adjustment of left and right images
☆ Wireless mouse keyboard, easy control
Three-channel arc type hard screen
In the splicing of curved screens, the projection screen generally selects a hard screen. Because it is easy to shape, it is not easy to damage, and the screen can be flat in any splicing space, and it will not be deformed for a long time. In order to achieve a more splicing effect, in this splicing scheme, the selection of the curved hard curtain follows the following characteristics:
☆ Made of epoxy resin, double metal coating inside and outside, reflecting the incident light to form a display
☆ Ultra-high contrast and superior anti-environmental light interference, blacker black, brighter color
☆ Even in brightly lit indoors, or even outdoors without direct sunlight, the fog of the traditional projection screen image can be eliminated, providing a bright and clear perfect image.
☆ Precision giant mirror mold diameter up to 5 meters
☆ The projected light reaches the screen evenly, and the overall brightness of the screen is the same, no spot
☆ Provides a wider viewing angle while achieving high brightness
