Abstract

Recently, the generation of three-dimensional photo-realistic models has been one of the most interesting topics in
photogrammetry and LiDAR. The purpose of this research was to study, compare, and asses the use of close-range
photogrammetry and terrestrial laser scanning techniques to reconstruct 3D objects. The two façades of Shorouk Building
were chosen in this study. The results indicated that terrestrial laser scanning technique was accurate enough for precise
three dimensional applications. The same results were obtained by close-range photogrammetry technique. for wide
facades, it is important to divide the facade into several parts for the purpose of achieving high accuracy in CRP technique
and each division is considered as a separate façade.
