The auto-calibration system allows automatic alignment of multiple video-projectors
France - Modulo Pi has announced the immediate availability of a new multi-projector auto-calibration module. Available as an option for the Modulo Player and Modulo Kinetic media servers, the auto-calibration system allows to automatically align multiple video-projectors on planar, curved, and dome surfaces for a pixel-perfect projection.
Working with Modulo Player, up to one server can be supportedfor example up to six WQXGA outputs, or four 4K outputs. Working with Modulo Kinetic, the auto-calibration option supports multi-server configuration, resulting in an unlimited number of outputs and resolution support. Modulo Pi’s auto-calibration system can handle independent calibration groups, as well-stacked video projectors.
In addition, a versatile masking feature ensures a fine-tuned projection. Fully developed by Modulo Pi, the auto-calibration module relies on Power over Ethernet (PoE) cameras to offer fast and simplified cabling. Using the Modulo Pi media servers equipped with the auto-calibration option, high-precision edge blending, warping, and media playback is achieved within minutes and with zero latency.
In summer 2019, design and production company ECA2 worked with a preview version of Modulo Pi’s auto-calibration module for The Legend of Pangu, a spectacular show in the new Chinese Culture Exhibition Centre in Lanzhou. The auto-calibration module was used to automatically align 20 x Christie projectors and deliver a 2.800 sqm 3D video mapping on a dome surface.
“This is totally revolutionary technology,” says Clément Rabréaud, technical director for The Legend of Pangu. “It takes just 13 minutes to run, which means that if a projector ever needs to be replaced, the whole system is back in focus quickly.”
