3D modeling of cultural heritage objects with a structured light system
Akça, Mehmet Devrim (Univ Agean, 2012)3D modeling of cultural heritage objects is an expanding application area. The selection of the right technology is very important and strictly related to the project requirements, budget and user's experience. The ... -
Co-registration of surfaces by 3D least squares matching
Akça, Mehmet Devrim (Amer Soc Photogrammetry, 2010-03)A method for the automatic co-registration of 3D surfaces is presented. Die method utilizes the mathematical model of Least Squares 2D image matching and extends it for solving the 3D surface matching problem The transformation ... -
FORSAT: a 3D forest monitoring system for cover mapping and volumetric 3D change detection
Stylianidis, Efstratios; Akça, Mehmet Devrim; Poli, Daniela; Hofer, Martin; Gruen, Armin W.; Sánchez Martín, Víctor; Smagas, Konstantinos; Walli, Andreas; Altan, Mehmet Orhan; Jimeno, Elisa; Garcia, Alejandro (Taylor and Francis Ltd., 2020-08-02)A 3D forest monitoring system, called FORSAT (a satellite very high resolution image processing platform for forest assessment), was developed for the extraction of 3D geometric forest information from very high resolution ... -
Monitoring of a laboratory-scale inland-delta formation using a structured-light system
Akça, Mehmet Devrim; Seybold, Hansjörg J. (Blackwell Publishing Ltd, 2016-06)A reduced complexity model, which simulates the process of fluvial inland-delta formation, has been developed in a previous study. The results have been compared and validated with a laboratory experiment. This work ... -
Photogrammetric monitoring of an artificially generated shallow landslide
Akça, Mehmet Devrim (Wiley-Blackwell, 2013-06)An artificial rainfall event was applied to a forested slope in Ruedlingen, northern Switzerland. The experiment triggered a landslide which resulted in mobilising about 130m3 of debris. The event was monitored by a ... -
Precursors of instability in a natural slope due to rainfall: a full-scale experiment
Askarinejad, Amin; Akça, Mehmet Devrim; Springman, Sarah Marcella (Springer Heidelberg, 2018-09)A full-scale landslide-triggering experiment was conducted on a natural sandy slope subjected to an artificial rainfall event, which resulted in mobilisation of 130m(3) of soil mass. Novel slope deformation sensors (SDSs) ... -
Quality assessment of 3D building data
Akça, Mehmet Devrim; Freeman, Mark; Sargent, Isabel; Gruen, Armin W. (Wiley-Blackwell Publishing, 2010-12)Three-dimensional building models are often now produced from lidar and photogrammetric data. The quality control of these models is a relevant issue both from the scientific and practical points of view. This work presents ... -
Topography of inland deltas: Observations, modeling, and experiments
Seybold, Hansjörg J.; Molnar, Peter; Akça, Mehmet Devrim; Doumi, M.; Tavares, M. Cavalcanti; Shinbrot, Troy; Andrade, Jose Soares; Kinzelbach, Wolfgang; Herrmann, Hans Jürgen (Amer Geophysical Union, 2010-04-28)The topography of inland deltas is influenced by the water-sediment balance in distributary channels and local evaporation and seepage rates. In this letter a reduced complexity model is applied to simulate inland delta ...
