  • 摘要:This paper introduces a complex, low-cost road pavement measurement system designed primarily for pothole and crack detection. The onboard system is composed of a GPS/INS navigation unit, an image acquisition module, and a photogrammetric and image- processing subsystem. Due to the use of structured light and the availability of accurate navigation data, the 3D coordinates of the road points, in the form of cross profiles, as well as the size and location of the potholes, can be derived from the images at cm-level relative accuracy. For the road classification the International Roughness Index (IRI) can be derived. This paper also discusses the potential future developments of the system; it reports on the initial investigations of applying single camera with laser line projection which can significantly simplify the overall procedure
