A Laser-based 3D Data Acquisition System for the Analysis of Pavement Distress and Roughness

In this report the authors deal with the detection and classification of pavement cracks. Currently, ConnDOT is using Wisecrax® which is a commercial product supplied by Roadware. The authors develop a 3D laser based technique to detect the cracks in a certain pavement sector. They use phase shifting interferometer to store the 3D information of the pavement. Regular imaging systems are not able to estimate the crack depth. The proposed technique has the advantage of estimating the crack depth. The proposed laser based system can be used in conjunction with the Wisecrax® to improve its performance or as stand alone system. The authors used an improved multi scale wavelet algorithm to reduce the effect of the speckle noise.
