VIOSO has introduced LEDtools, a new auto calibration software for LED walls. The system uses camera-based analysis to automate geometric alignment and colour correction. It supports both standard and complex LED structures and helps visual teams complete installations faster and with higher accuracy.
LEDtools analyses flat, curved or hybrid LED surfaces with cameras. The software performs geometric alignment automatically, without manual mesh mapping. Its computer-vision algorithms read the true shape of the LED wall and create precise calibration data.
This automated approach shortens installation time, reduces human error and improves final image accuracy. Unlike tools adapted from projection systems, LEDtools is designed from the ground up as a native auto calibration software for LED walls, matching the pixel-level behaviour of SMD LEDs.
The software also provides automatic colour and brightness balancing. LEDtools measures each SMD pixel and adjusts it accordingly. This removes hotspots, colour shifts and uneven brightness across large LED walls. The result is a clean, natural and consistent image, even in demanding environments.
The system integrates VIOSO’s patented EyeView color-correction technology. A tracked camera captures the LED wall from the relevant viewing angle. This ensures accurate colour reproduction for immersive spaces, simulation workflows and virtual production stages.
For applications that require precise spatial accuracy, LEDtools supports real-time viewpoint tracking. The software monitors the viewer’s position and adjusts the virtual frustum automatically. Objects appear correct in shape, scale and depth, even when displayed on curved or non-planar LED surfaces.
This capability is essential for XR stages, CAVE rooms and driver-in-the-loop simulators, where visual accuracy affects immersion and performance.
LEDtools connects natively to many real-time render engines and can also be integrated into new workflows through an SDK. The software works independently of LED controllers, media servers or custom rendering pipelines. This allows integrators to add the system without replacing existing hardware or redesigning established workflows.
As LED installations continue to grow in scale and complexity, automated calibration becomes increasingly important. LEDtools offers a full platform for camera-based calibration with:
Christian Steinmann, VIOSO’s chief technology officer, said the technology is unique in today’s market. He emphasised that EyeView enables unmatched image fidelity and noted that LEDtools expands possibilities for simulation, virtual production and immersive visual environments.
