Laser Scanning for Terrestrial Photogrammetry, Alternative System or Combined with Traditional System?

Traditional photogrammetric method has been a system for documentation, 3D modelling for long years. After the development of digital photogrammetrical systems, map products can be monitored in CAD platforms. Placing models in CAD had verified flexibility for getting information from model and easy editing for modelling. Terrestrial Laser Scanning Systems provide modelling of objects without scale and complexness. Likewise the combination of laser scanning method and photogrammetric method or taking in the consideration of the laser scanning method as an alternative method has been become a discussing topic. In this study, the study area has modelled with both systems and after completed the comparison and combination of the both systems. 3D Model of the building of University of Karlsruhe, Institute of Photogrammetry and Remote Sensing in Germany had been evaluated by photogrammetric method. The 3D model of same scenery had been created by terrestrial laser scanning method. Then the comparison of results from both systems had been done. To fusion the elevation data had been taken from laser scanning and the spatial data from photogrammetric evaluation. The process steps had been explained and the results given. * Corresponding author.
