VIOSO has launched LEDtools, a new software platform designed specifically for automatic calibration of LED displays. The company says the system brings its projection-calibration technology natively into the LED domain, providing camera-based geometric alignment, colour balancing and dynamic correction for curved, non-planar or large-format LED structures.
At the core of the solution is fully automated geometric calibration, which removes the need for manual mesh mapping and reduces setup time from hours to minutes. VIOSO says it also delivers more consistent results across complex surfaces and stabilises the commissioning process for large installations.
Christian Steinmann, CTO of VIOSO, said: “This technology is truly unique on the market. Thanks to our patented EyeView colour-correction technology, we achieve unmatched image fidelity. LEDtools measures the performance of every individual SMD pixel and adjusts brightness and colour automatically, based on a tracked camera capturing the relevant viewing angle.”
The EyeView process is designed to ensure uniform brightness and colour reproduction across the LED canvas, eliminating hotspots and colour shifts. VIOSO notes that this viewpoint-correct colour stability is particularly important for virtual production volumes, driving simulators, CAVE systems and other applications requiring high visual realism.
LEDtools also incorporates dynamic viewpoint correction, continuously tracking a viewer’s or pilot’s position and adjusting the rendered frustum in real time. This helps maintain geometric accuracy on curved or irregular LED surfaces, supporting simulation and XR workflows.
Developed natively for LED rather than adapted from projection tools, LEDtools uses computer-vision algorithms for both geometric and colour alignment. It integrates with various render engines and can be embedded into custom pipelines via SDK, allowing use with a wide range of controllers and media servers.
Concluding, Steinmann said: “With LEDtools, VIOSO sets a new standard for automatic LED display calibration: camera-based, dynamic, colour-accurate, precise, and seamlessly integrable. The software unlocks new possibilities for simulation, virtual production and immersive environments – wherever maximum accuracy and efficiency are required.”
