Abstract: The traditional tunnel section collection method is low in efficiency. This paper introduces the field collection and data splicing technology of the Leica RTC360 3D laser scanner in the tunnel section, and combines the design line to extract the tunnel section. The research results show that the section obtained by this high-density, high-precision point cloud collection can meet the measurement requirements of the tunnel crosssection measurement.
Keywords: 3D laser scanning; data splicing; cross section
