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 ...
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 ...
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 ...
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 ...
A precision estimation method for volumetric changes
(IEEE, 2019-06)
Earth surface changes are often computed by comparing the sequences of digital elevation models (DEMs) so called the DEM of difference (DoD) method. We present an operational DEM generation, co-registration and DoD comparison ...
Total least squares registration of 3D surfaces
(Copernicus GmbH, 2013-10-16)
Co-registration of point clouds of partially scanned objects is the first step of the 3D modeling workflow. The aim of coregistration is to merge the overlapping point clouds by estimating the spatial transformation ...
Photogrammetric deformation monitoring of the second Bosphorus Bridge in Istanbul
(International Society for Photogrammetry and Remote Sensing, 2014)
Improving the efficiency of bridge inspection and minimizing the impact of dynamic load on the long term deterioration of the bridge structure reduces maintenance and upkeep costs whilst also improving bridge longevity and ...
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) ...
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 ...
