    摘要: PROBLEM: Efficiently generating digital terrain model (DTM) having high elevation surface accuracy and high point density, and suitable for controlling pavement milling machines during road repairs. SOLUTION: Combination of motorized levelling and Stop-Go mobile laser scanning system, including train of three vehicles, which are at standstill during measurements, and which move in unison in between measurements. Middle vehicle carries laser scanner, elevation sight, and GNSS receiver. Front and rear vehicle each carry levelling rod; front vehicle also carries GNSS receiver. During measurement cycle, laser scanner generates point cloud, while GNSS positions of middle and front vehicles and elevations at the resp. positions of front and rear vehicles are determined. After measurement cycle, vehicle train moves until rear vehicle halts at previous GNSS position of front vehicle, etc. When all measurement cycles are completed, collected data is integrated and transformed into a DTM.
