First time using our tracking system on an LED wall. It was at ARRI's fantastic LED volume in Uxbridge, what an amazing facility! Our system is based on Ultra Wideband and used 12 fixed beacons set around the volume with a UWB receiver and IMU on the camera. Our system measures the position and angles of the camera, and this data is fed into the Unreal Engine which is driving the real-time 3D graphics on the enormous LED wall (5m high, 360 degrees). We take Focus, Iris and Zoom data from the camera and send this to the Unreal servers to help create a realistic background. #virtualproduction #rtls #cameratracking #indoorpositioning
