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.

Re: Laser Scanner for Surveying Roads at 100 km/h
I could be wrong but this is a profiler, correct? I guess it does measure in three dimensions, just not the three we would normally expect (offset, height, chainage as opposed to x,y,z)

I think you're right Phill, this is used for rutting, cracking, potholing, etcetera.
Not an MLS system in the sense you and we use it.

Re: Laser Scanner for Surveying Roads at 100 km/h
I have a similar system built into my car for finding pot holes
If you don't see that there is nothing, then you are kidding yourself.
