Comparison Between Terrestrial Laser Scanning and Close Range Photogrammetry for Three-Dimensional Modeling

Abstract

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