Automated Survey of Pavement Distress based on 2D and 3D Laser Images

摘要

Despite numerous efforts in recent decades, currently most information on pavement surface distresses cannot be obtained automatically, at high-speed, and at acceptable precision and bias levels. This research provided seed funding to produce a functional prototype developed by the research team with line lasers and 3D cameras that overcame many existing limitations, with the capability of obtaining 3D pavement surface models at true 1mm resolution with full-lane coverage, and conducting real-time analysis on rutting and cracking. In addition to the project funding, WayLink Systems Co. provided needed resources in hardware and other support to complete the research.
