Comparative Studies on Methods for 3D Modelling of Urban Area

The book serves as a rigorous introduction to the basic principles and practice of the building 3D model creation process. It presents five photogrammetric methods utilised for 3D modelling of urban area, as follows: close range photogrammetry, by using digital non-metric images taken with a Canon EOS Rebel XSi/450D digital camera, UAV photogrammetry by using digital non-metric images acquired with a low-cost UAV platform, namelly DJI Phantom 3 Standard, the traditional technologies of terrestrial photogrammetry by using metric images, acquired with terrestrial photogrammetric camera UMK 10/1318, the terrestrial laser scanner method (TLS) and the aerial laser scanner method (ALS). We are reviewing the data sources, their preliminary processing to be brought in a common system and the software used for the creation of the final 3D models of the buildings. The comparative studies between the five methods were accomplished by analyzing the object space representation fidelity and the precision of the 3D models created for the buildings that were study in this book.
