Terrestrial laser scanning technique has represented one of the more advances occurred in last years field data acquisition. Time-of-Flight (TOF) systems provide a fast and reliable tool to measure millions 3D points allowing very effective dense measurement surface geometry. Nowadays, generation high quality models is practice applied different kind objects: small or medium size artworks, parts human body, cars, buildings, civil infrastructures (like dams, bridges, plants, etc.) whole archaeological sites as well. In most cases, order capture object geometry number single scans need be acquired from positions then stitched together (i.e. registered each other) generate full model. The automatization registration multiple terrestrial scanner (TLS) still represents attractive research field. chance automatically align several point clouds would reduce processing costs terms time resources. addition it allow even non-specialist users produce with good quality. This paper contributes this area by presenting method for automatic TLS systems. proposed solution an extension large datasets range procedure we developed few ago modelling close-range scanners. Such procedure, based on spin-images (SIs) algorithm, been improved introduction multi-resolution that generates pyramid speed up matching between adjacent scans. results present show can successfully density complex structures Cultural Heritage.
