Evaluation of the Road Surface Quality Inside the Road Tunnel

Abstract

The paper discusses a method for quantitative evaluation of the road surface based on processing of the cloud of 3D points. The points are measured by high-speed laser scanner mounted on the vehicle. Such approach allows to scan the road surface without the need to stop the traffic inside the tunnel. The obtained data are processed in offline mode. The processing algorithm evaluates the structure (texture) of the surface, which has the direct impact on the safety of the road transport.
