Fraunhofer IPM develops optical systems for the detection of contact wire wear, contact wire position, clearance profile, position of poles, rail profile, and train geometry. High-resolution laser scanners combined with fast image processing provide the necessary measurement data for planning specific maintenance work. The sensors quickly, precisely, and reliably record the measurement data at travel speeds of 100 kilometers per hour and more. Our measuring systems are used worldwide to monitor the condition of railway networks.

At Fraunhofer IPM, we utilize the entire 3D data processing chain — from robust systems that capture three-dimensional geometries and the location of objects to data analysis and visualization. The Contact Wire Inspection Systems (CIS and CIS-Low Speed) are used for simultaneously detecting contact wire position, contact wire wear, and pole position.
