NONCONTACT PAVEMENT CRACK DETECTION SYSTEM

摘要: A system has been developed for the Texas State Department of Highways and Public Transportation automated crack identification with lasers as primary sensors. The quickly easily provides summary information network pavement cracking evaluation. development effort involved three stages. first two stages determined detection capabilities laser probes on department's surface dynamics profilometer. hardware obtained software implementing real time reporting are described. includes Selcom probes, Motorola open-ended VME architecture, a Compaq portable personal computer. implements algorithms procedures. can provide measurements at normal highway driving speeds.
