The Fraunhofer Institute for Physical Measurement Techniques IPM has developed a laser scanner for measuring road surfaces with high precision. A single high-resolution laser scanner scans the topography of the road surface across a span of four metres. Even at speeds of up to 100 km/h, measurements are accurate to between 0.15 and 0.3 millimetres. In cooperation with a road surveying specialist, Fraunhofer IPM has already scanned a total of 15,000 kilometres of highway and other major roads across Germany.
