English abstract:
This article describes the surveying work and the creation of a 3D model of a Pegasus statue, which builds the basis for a static analysis. The supporting legs of the statue were surveyed with the close-range laser scanner Minolta VIVID 900. Approx. 45 individual scans were required to cover each leg. The rest of the statue was surveyed with the terrestrial laser scanner Riegl LMS-Z420i with 8 individual scans. The surveying of the statue using these two laser scanners is particularly interesting because the statue represents a rather `small´ object for a terrestrial laser scanner, whereas for a close-range laser scanner it represents a rather `huge´ object. With the aid of photos of the statue, the relative orientation between the different laser data was determined in the course of a hybrid bundle block adjustment. Finally a `waterproof´ 3D model of this complex statue was derived.
