Abstract

The rut results based on the line-laser rut measurement are often subjected to the vehicle bumps, vehicle pitch changes in practical applications. The principle of line-laser rut measurement is described and the factors are analyzed from the perspective of optical imaging. A new method of symmetrical line-laser rut measurement is proposed. This method uses symmetric line-laser imaging system and can effectively reduce the rut test errors caused by the vehicle bumps, vehicle pitch changes. Experimental results show that the symmetric line-laser rut measurement can be used to detect road surface rut.
