Research on accuracy obtained in laer scanning measurement Process

The paper presents the results of performed accuracy analysis for the spatial models obtained during the laser scanning process. The scan of the different elements beginning from the regular geometric surfaces to built up architectonical forms made at The Main Building of the Warsaw University of Technology were the object of conduction analysis. The most technologically advanced and accrued geodetic instruments like: terrestrial laser scanner Z+F Imager 5006, total station Leica TCRP 1201+ and RMS (Ramote Measuring System) set on the base of theodolite Wild T2002 were used to realize the project. The real precision of the new survey technique could rise doubts and need to be check during the specialized researches. Improvement of measurement technique and data post processing also should be carried out. In spite of a large point number acquire from scanning and additionally intensity value of surveyed objects. The model handling is supported by specialized system software tools. Perfomed analysis deliver data which suggest that technique wchich were used is suitability for presicie determination of engineering object geometry and for deformation determination. The technology accuracy were estimated for the particular case tasks.
