The Laser Crack Measurement System (LCMS) utilizes high-speed cameras, custom optics, and laser line projectors to acquire both 2D images and high resolution 3D profiles of the road. This system has been designed to acquire details of the road surface that allow for the automatic detection of cracks and the evaluation of macro-texture and other road surface features. The LCMS system can be operated in all types of lighting conditions while still collecting accurate data. Various pavement types ranging from dark asphalt to concrete can be measured at survey speeds up to 65 mph and on roads reaching 4m in width. Rutting is measured and characterized using more than 4,000 points.
The LCMS produces highly accurate and repeatable results. The system has been proven through the collection of large-scale multi-state routes and test sites. Automated processing methods allow for the extraction of accurate data while adding to the cost-effectiveness of the system, and increase the repeatability results beyond what could be obtained through manual rating methods.
