To project a homogeneous image onto the 7m * 5m wide flexible rear screen, NANCO used 16 projectors, each controlled by its own workstation. Remember that this was before the 4K era!
In order to manage the 16 workstations and the extra workstation for the applications as well as to meet the high image quality requirements, 3DEXCITE DELTAGEN, delivering both, was installed. The entire setup was then controlled from the operator desk, including a screen and a touch screen.
As the projection screen was submitted to air movements affecting the image quality the projectors had to be manually calibrated regularly.
In December 2005 the 7m * 5m wide powerwall visualizing homogenous and high quality 1:1 truck cabs was inaugurated, perfectly complementing VGTT:s approx. 15m * 20 m large show room.
By 2013-2014 VGTT wanted to upgrade its visualization area with new systems, a brighter screen, an extended audio system and improve computer performance. The challenge was to implement the upgrade within the same visualization area, i.e. without any impact on reserved space to show case 3-4 trucks 1:1 in the exhibition room.
By then 4K projectors were available, which would have solved the previous challenge of creating a 7m * 5m large homogeneous and high quality image. But as 4K rear projection alternatively 4K mirrored rear projection require more space than what was available in the given setup, none of these projection alternatives were an option.
NANCO upgraded therefore the setup with 16 high resolution projectors, delivering a brighter image, 16 high-performance workstations and an extended audio system including microphones and in-ceiling speakers.
In order to optimize the calibration of the projectors guaranteeing high image quality NANCO installed a system for automatic calibration, making the entire calibration process more efficient.
NANCO succeeded in implementing a complete upgrade behind the scene. The 7m * 5m wide high-performance powerwall at VGTT visualizes bright and high resolution 1:1 truck cab images.
