Application of digital photogrammetry to the quantification of road surface distresses

This paper describes the application of close-range photogrammetric and digital image processing techniques to obtain the required raw data for future assessment of any given road surface. The potential capability and reliability of a workstation-based digital photogrammetry system for quantifying road surface delamination was demonstrated and assessed. Surface measurement is represented by ortho-image, overlay contour wit ortho-image, as well as digital elevation model of the delamination area. Preliminary results on delamination indicate that the extent of the road surface distress can be quantified swiftly and accurately when compared to the conventional method.
