Paper Abstract

Pavement rut is one of the major highway diseases. In this article, the method of measuring rut based on laser triangulation is created. The rut-resolution model is established to design the parameters of optical system and the laser profile of road image was extracted by median filter and wavelet transform. An accurate calibration method on large field of view consisting of 28 sub-FOVs calibration and road profile reconstruction is also created. The process of calibration experiment and a new calculation method of rut is described. The measurement results were showed, which concluded the static test of gauge block and the dynamic measurement on highway. The conclusion is with this method using single CCD camera and two semiconductor laser of 808nm wavelength can reach the accuracy of 1mm on rut measurement in tough circumstance.
