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 ...
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 ...
Shapes and statistics of the rogue waves generated by chaotic ocean current
(International Society of Offshore and Polar Engineers, 2016)
In this study we discuss the shapes and statistics of the rogue (freak) waves emerging due to wave-current interactions. With this purpose, we use a simple governing equation which is a nonlinear Schrödinger equation (NLSE) ...
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 ...
Stochastic surface mesh reconstruction
(International Society for Photogrammetry and Remote Sensing, 2018-05-30)
A generic and practical methodology is presented for 3D surface mesh reconstruction from the terrestrial laser scanner (TLS) derived point clouds. It has two main steps. The first step deals with developing an anisotropic ...
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 ...
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 ...
Improving the calibration time of traffic simulation models using parallel computing technique
(Institute of Electrical and Electronics Engineers Inc., 2019-06)
The calibration procedure for traffic simulation models can be a very time-consuming process in the case of a large-scale and complex network. In the application of Evolutionary Algorithms (EA) such as Genetic Algorithms ...
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 ...
