Paper Abstract

The necessary basis for any cost-effective highway and bridge deck pavement management program is reliable complete and up-to-date information concerning the state of pavement surface. An imaging system using the Shadow Moire method for the quantitative inspection of highway pavement surface in real-time has been developed which includes image analysis software for performing image enhancement and the analysis of Moire fringe patterns. Several enhancement schemes and thinning algorithms have been implemented and tested. The prototype system possesses a high degree of automation and gives enhanced pictures and accurate results. Also needed surface geometry information may be obtained efficiently and effectively.
