Road Profiling




The Hermes system comprises a mobile unit, i.e., a special measurement vehicle having laser projection and camera imaging equipment. Acquired data is logged by a computer using a relational database. Data is subsequently post-processed using Structured Query Language-based queries, together with sophisticated custom-developed data analysis software.

The measurement principle is based on projecting a laser line on the road surface and recording its image using a high resolution camera of high frame rate. The deviation of the laser line is measured, which corresponds to undulations of the road surface.

A novel automated pothole detection algorithm has also been developed to automatically characterise the quality of the road surface and detect potentially hazardous defects. A specially-developed GNSS controller provides high accuracy localisation of acquired measurement data.
