The paper presents a combined analysis of terrestrial laser scanning (TLS) and structure from motion (SfM) photogrammetric measurement to determine an accurate model of the surface shape of a thin-walled dome. The analysis takes into account several factors that may affect the accuracy of measurement. In TLS measurements. these are related to scattering of the beam and its penetration... https://www.roneverhart.com/Field-Slacks-Mens-p10549/
