In particular, mobile laser scanning systems are nowadays able to provide realistic 3D elevation profiles of a road to detect anomalies. In this context, this study utilizes a high-accuracy high-speed mobile mapping vehicle and evaluates a weighted longitudinal profile as an improved measure for evenness analysis. For comparison a classical method with a rolling straight edge was evaluated on the same road section and observed effects are discussed. The second focus is the areal reconstruction of the road thickness. For this purpose, a modern method was developed to spatially synchronize two high-speed laser scans using Citation: Skalecki, P.; Sesselmann, M.; Rechkemmer, S.; Britz, T.; Großmann, reference boxes next to the road, to transfer the point clouds into a surface model and to calculate A.; Garrecht, G.; Sawodny, O.
