Determining pull - out deformations of bonded metal anchors embedded in concrete by means of photogrammetry
(International Society for Photogrammetry and Remote Sensing, 2012)
Chemical anchorages are applied in many engineering implementations, particularly strengthening of reinforced concrete structures. During strengthening procedure; chemical anchorages should be tested, since they supply to ...
Photogrammetric monitoring of an artificially generated shallow landslide
(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 ...
3-Dimensional pre- and post-fire comparison of forest areas
(International Society for Photogrammetry and Remote Sensing, 2018-03-06)
Forest agencies give special attention to forest fires where post-disaster loss can rarely be gauged in a quick and economic way unless an appropriate technology is adopted. Determination of the planimetric and volumetric ...
Laboratory flume experiment with a coded structured light system
(International Society for Photogrammetry and Remote Sensing, 2012)
The topography of inland deltas is influenced chiefly by the water-sediment balance in distributary channels and local evaporation and seepage rates. In a previous study, a reduced complexity model has been applied to ...
Quality assessment of 3D building data
(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 ...
Co-registration of 3d point clouds by using an errors-in-variables model
(Copernicus Gesellschaft MBH, 2012-08-25)
Co-registration of point clouds of partially scanned objects is the first step of the 3D modeling workflow. The aim of co-registration is to merge the overlapping point clouds by estimating the spatial transformation ...
Precursors of instability in a natural slope due to rainfall: a full-scale experiment
(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) ...
A generic point error model for TLS derived point clouds
(SPIE-Int Soc Optical Engineering, 2017-06-26)
This work aims at developing a generic and anisotropic point error model, which is capable of computing magnitude and direction of a priori random errors, described in the form of error ellipsoids for each individual point ...
Pre- and post-fire comparison of forest areas in 3D
(Springer Berlin Heidelberg, 2019)
A satellite processing platform for high resolution forest assessment (FORSAT) was developed. It generates the digital surface models (DSMs) of the forest canopy by advanced processing of the very-high resolution (VHR) ...
An emprical point error model for TLS derived point clouds
(International Society for Photogrammetry and Remote Sensing, 2016)
The random error pattern of point clouds has significant effect on the quality of final 3D model. The magnitude and distribution of random errors should be modelled numerically. This work aims at developing such an anisotropic ...
