Abstract
Terrestrial laser scanning (TLS) is capable to be a reliable deformation monitoring device with high-precision for concrete composite structures. Measurements based on TLS for an arch structure with monotonic loading is carried out. In this paper, comparison between original and optimized extraction of point clouds are presented. Surface approximation is implemented, where the vacant measurement area is also covered and the uncertainties of different-order surfaces are investigated. The results of surface approximation based on TLS measurement have certain relation with surface roughness of specimen, which will be eliminated by subtraction in deformation calculation.
