London's Science Museum’s 'Who Am I?' interactive visitor experience is using Calibre UK's PremierViewProHD Image Warp Processors to warp and blend incoming video signals, while retaining absolute signal quality.
Calibre image processing lies at the heart of the Threshold zone, which forms a dramatic entrance to the gallery featuring moving coloured particles that are constantly projected onto the floor of a long catwalk with seamless projection.
Visitors are drawn' along the floor by the colours and - as they approach the wall at the end - a concealed camera captures the infra-red reflections given off by each individual.
These are then translated into a personal, particle-based image that runs down the wall and onto the floor, mimicking each body's movement in real time.
Five Panasonic 6000 series projectors are positioned out-of-sight and driven at angles to fulfil the project brief of seamless imaging moving along.
This created a challenge for systems integrator Sarner, according to the company's head of engineering, Chris Hawes.
"At the time we tendered for the project, there was no solution on the market capable of achieving a seamless vertical and horizontal video wall with 180-degree interaction,” he said.
"Fortunately, by connecting PremierViewProHD Image Warp Processors from Calibre to each of the projectors, we were able to warp the projected images and blend them back into shape to create a single, continuous image.
"Visitors can walk within 1.9m (6ft) of the wall without affecting the projection at all."
