    • Abstract
  • A method for fast pavement ruts detection and system calibration with laser triangulation was proposed and implemented on a vehicle-borne road laser rut-meter.For real-time ruts measuring and satisfyingly dense road profiling,the global and local thresholds were applied and the local maxim grade values and neighbor gray values were calculated to detect and extract laser lines.A method of calibration modal creation based on a Delaunay triangulation was proposed to backproject the world coordinates of laser points.Manual rut measurements and auto rut measurements utilizing the proposed method were carried out on selected road segment,respectively.The results show the auto measurements consist with the manual measurements,and the proposed method is reliable for pavement ruts measurement.
