Automated Model Creation from Aerial Photography

3-Dimensional Building Details from Aerial Photography for Internet Maps

This paper introduces the automated characterization of real estate (real property) for Internet mapping. It proposes a processing framework to achieve this task from vertical aerial photography and associated property information. A demonstration of the feasibility of an automated solution builds on test data from the Austrian City of Graz. Information is extracted from vertical aerial photogr...

Advantages and Disadvantages of the Hough Transformation in the Frame of Automated Building Extraction

This paper investigates the outcome of building extraction techniques from optical aerial and spaceborne high resolution data when applying Hough Transformation procedures. The proposed workflow consists of 4 major steps, namely the pre-processing of the data, nDSM (normalized Digital Surface Model) creation, building localization and building extraction. The advantages and disadvantages of thi...

Automated Resonant Wireless Power Transfer to Remote Sensors from an Unmanned Aerial Vehicle

The Use of Photogrammetry and Lidar for Landscape Roughness Estimation in Hydrodynamic Studies

Flooding is a major problem for many countries causing damage to the environment and pressures on human activity. Engineers use Manning’s coefficient of roughness to determine water flow over floodplains which is a vital parameter in hydrodynamic studies. The coefficient is mainly a property of the ground surface texture and the changes in water surface elevation. The traditional method of dete...
