The authors investigated the potential capabilities and accuracy of the PC-based stereovision system in quantification of pavement rut depth. Three rutted sections of flexible pavement were used in the investigation. Selected highway pavement sections were chosen, using representative criteria that ensured randomness in parameters, for semiautomatic rut depth quantification. Surface measurements were modeled by two-dimensional and three-dimensional plots, as well as contour maps for the rutted areas. Results derived by this procedure were compared with those derived by the manual conventional method using a straightedge to check accuracy. The comparison revealed that stereovision using dual charged-coupled device cameras mounted on a stand on a moving vehicle has a consistent potential accuracy of about 1.5 cm on average in measuring the rut depth for the three sections. This finding was compatible with the operator's ability to point to the conjugate image points, which has a potential accuracy of about 1.5 to 3 cm. Remoteness, safety, and real-time potential due to the use of digital images are some of the advantages of using the stereovision procedure to quantify rut depth.
