Measurement and Evaluation of Pavement Leveling Based on Portable 3D Laser Scanner
In order to solve the problem of complex structures and high costs of the current highway pavement measurement and evaluation methods,a measurement and evaluation method based on a por-table 3D laser scanner was constructed.The 3D laser scanner was adopted to measure asphalt highway pavement data and acquire 3D point cloud data of the pavement.The 3D elevation surface of the pave-ment was obtained after analysis and processing,and the RegularizeData3D algorithm,empirical modal decomposition(EMD),and other methods were utilized to preprocess the data,reconstruct the regional pavement unevenness,and obtain the leveling data series of the corresponding pavement.Finally,the power spectrum density of the experimental pavement was calculated and analyzed,and the entire ex-perimental pavement condition was evaluated based on the statistical results.The experimental results show that the system can better reconstruct the characteristic information of the measured regional pave-ment.The pavement leveling is mostly concentrated in grades A and B,and the overall pavement level-ing is above B grade.
