Developing an Inexpensive Automatic Video Recording System for Pavement Crack Analysis
Huge amounts of data need to be collected to closely monitor a pavement surface to determine preventive and corrective maintenance. A periodic evaluation of the rate of progress of the pavement deterioration helps highway engineers to determine the most efficient way in which to maintain a particular highway pavement. Typically, a multi-camera video system, along with an image processing system, is mounted in a van to record pavement conditions at high speeds. However, the cost of such a system is very high. Also, a high degree of accuracy is sacrificed for road-speed operation. Manual observation of a pavement block, although highly accurate and detailed in coverage, is very slow and labor intensive, yielding non-standard and non-repetitive results. The goal of this project was, therefore, to develop a system that is small, cheap, and portable, combining transducers with video image processing, including location referencing, that can be quickly located over pavement sections to be sampled for crack condition or surface texture.
