摘      要：In recent years,various information and communication technology(ICT)devices measuring three-dimensional(3D)point cloud data have been developed and widely used for the application of pavement surface ***,ICT devices have generally been developed not only for measuring road surface profiles but for various geo-reference point *** this background,the validation of surface profiles acquired with ICT devices fulfils an important role in proving the reliability of measurement result composed by point *** study proposes a wavelet transform agreement(WTA)which involves a normalization factor of profile amplitude for further improvement in the wavelet-based coherence *** WTA analysis allows evaluating similarity/dissimilarity of two profiles considering both the location and wavelength *** this purpose,a terrestrial laser scanner(TLS),a mobile mapping system(MMS),and an unmanned aerial vehicle(UAV)are employed to prove the advantage of WTA in practical *** a result,the advantages of WTA analysis are clearly recognized in the optimization for the measurement interval of TLS,the multi-line measurement of MMS for ride quality improvement of a pavement,and the efficient operation of UAV in terms of the flight *** paper also shows the identification of aging development for surface roughness over time in terms of locations and *** findings help not only to guarantee the accuracy of profile measurements but to realize the sophisticated way of using 3D point clouds acquired with ICT *** outcomes of this study contribute to the increase of productivity for pavement works with improving the quality of surface profile measurement.
