Solution Background
As an important window for comprehensively promoting the image of the city and an important platform for external communication, the Urban Planning Exhibition Hall is mainly used to show the vicissitudes of urban construction and the achievements and overall trends of urban development in an all-round and multi-angled manner.  Based on the traditional display methods such as display panels and models, the Urban Planning Exhibition Hall will integrate modern acoustic and optical technologies such as large-screen video wall controller, Multi-shaped LED display, multi-channel projection fusion, 3D projection fusion, and virtual simulation into the display link for vivid reproduction.

Application Requirement 

The urban planning exhibition hall is generally divided into several parts including general planning area, special planning area, historical exhibition area, cultural tourism area, and public interactive area. The exhibition video display system includes a large-screen mosaic display system, a projection fusion interactive sand table system, and a 3D projection fusion display. Systems, virtual simulation systems, etc.

Ultra-high-definition city planning video screen display

Use the image processor to collect multiple 4K ultra-high-resolution signals output from multiple graphics workstations, stitch them into a whole picture, and push them to multiple groups of large screens to achieve picture linkage. Full-view digital 3D real-world interactive demonstrations, showing the current status of urban construction and planning.

Multi-channel 3D fusion rendering

Through projection three-dimensional fusion technology, the history and culture of the city and the new look of the new city are presented to the audience from multiple angles, giving a super-sensing experience.

Virtual Simulation Interactive Application

Based on the multi-channel projection virtual simulation fusion technology, it can combine the GIS and human-computer interactive application of the true three-dimensional description and performance of the planning results and schemes to realistically reproduce the scenes of the planning schemes in the current urban landscape, enabling planners, designers, and decision-makers. In the process of scene interaction, the user and the user observe the real three-dimensional three-dimensional landscape, and visually produce an immersive feeling.


The large-screen display system of the planning exhibition hall is composed of high-performance image processors and distributed fusion processing systems. All equipment adopts pure hardware architecture and operates stably. The system has excellent image processing capabilities, supports multi-channel 4K picture stitching, and achieves higher resolution and large pictures. The distributed fusion system can realize the fusion of various special-shaped screens such as flat screens, curved screens, ring screens, and ball screens. The proprietary frustum algorithm for virtual simulation applications can realize the perfect fusion display of the simulation system screen. All equipment adopts a modular design, which has good stability, reliability and safety.

Solution Features

High reliability, high stability, and high flexibility

The system uses pure hardware advanced technology and system structure to improve system reliability and security; it provides redundant configuration, with module design, and expansion capabilities; it supports hot swapping of acquisition cards to reduce the impact of failures. Adopting a unified control management system, which can be flexibly operated, while supporting the corresponding iPad, Surface and other tablet computers.

Ultra-high-resolution signal acquisition

The system supports DVI, HDMI, VGA, SDI and other common format signal acquisition, supports Dual-Link DVI, HDMI1.4, Display Port interface, single port supports 4K ultra-high score acquisition, and supports multiple 4K signal input stitching for greater resolution Rate (12K, 16K, etc.) signal display.

Unified management of multiple groups of screen walls

Multiple groups of large display screens in the system, including LCD splicing screens, LED splicing screens, and projection fusion, can be unifiedly managed by one device, which can achieve screen linkage and multi-dimensional display of multiple sets of screens.

Camera automatic calibration technology

For the projection fusion display system, through the automatic sampling and correction of the camera, the digital consistency correction of the color consistency of multiple projectors can be achieved. Only the parameters of the fusion band can be analyzed, and the perfect fusion display effect is finally achieved.

The project

A planning pavilion is divided into three floors. Through multimedia projection, sand table, LED screen and other technologies, it fully displays the historical development, urban construction, and future planning of a city. The entire planning hall is shared with the 113 channels, including oval curtains, 360-degree ring curtains, electric glass curtains, 17-channel ultra-long curved curtains and other materials of different shapes and materials.

The 360-degree immersive theater in Yuedong, a city built in the exhibition area, is a highlight. It uses multiple graphics workstations to simultaneously play ultra-high-resolution film sources, uses 32 projectors to project ground screens, and 360-degree surround screens projected by 16 projectors, and realizes seamless connection through distributed fusion processing systems. Interaction. The overall picture is smooth and beautiful, giving the audience a sense of immersion.
