Plasser says this is its first machine to send data on absolute track geometry via the cloud directly to track maintenance machines. The EM100VT combines an inertial track geometry measurement system with an optical fixed-point procedure and GNSS/GPS georeferenced data, which enables the machine to capture absolute track geometry at speeds of 100km/h or more, which means the machine does not block tracks for too long.
The machine has stereo cameras including a 360o camera with infrared vision, while LED light panels maintain a standardised lighting situation. The position of fixed points - height and distance - are calculated in real time. With a frame rate of up to 200 frames/s and a resolution of 5MB, a large amount of data can be processed and synchronised. The machine can create a virtual image or digital twin of the track.
