3D BUILDING MODEL GENERATION FROM AIRBORNE LASER SCANNER DATA USING 2D GIS DATA AND ORTHOGONAL POINT CLOUD PROJECTIONS
LIDAR point cloud segmentation building model reconstruction automation
2015/8/13
Human operators use an intuitive procedure of rotating laser scanner point clouds into specific projections when trying to understand
the structure of buildings contained in the data. This procedure ...
FIRST EXPERIENCES WITH A MOBILE PLATFORM FOR FLEXIBLE 3D MODEL ACQUISITION IN INDOOR AND OUTDOOR ENVIRONMENTS – THE WAGELE
3D modeling registration omnidirectional vision laser range scanner
2015/8/7
Efficient and comfortable acquisition of large 3D scenes is an important topic for many current and future applications

Model reconstruction grammar building 3D
2014/7/24
The automatic reconstruction of 3D buildings has been an important research topic during the last years. In this paper, a novel method is proposed to automatically reconstruct the 3D building models f...
Experimental Assessment of the Accuracy of an Advanced Photonic-Bandgap-Fiber Model
Accuracy Advanced Photonic-Bandgap-Fiber Model
2015/8/7
From scanning-electron microscope images of the cross section of a photonic-bandgap fiber (NKT Photonics’HC-1550-02) we developed a realistic model for its permittivity profile that includ...
STREET REGION DETECTION FROM NORMALIZED DIGITAL SURFACE MODEL AND LASER DATA INTENSITY IMAGE
Street region detection laser scanner data normalized Digital Surface Model intensity image image processing techniques
2014/5/8
The urban road network extraction process can be simplified by firstly detecting regions corresponding to streets, allowing a substantial reduction of the search area. As a result, the extraction proc...
An Optimal Model for LSP Bundle Provisioning in PCE-based WDM Networks
Fiber optics and optical communications Networks
2015/5/21
A time-efficient resource optimization model for dynamic concurrent provisioning of connection requests at PCE is proposed. It is shown that a significant performance improvement can be achieved witho...
Novel Analyzing Model of Bi-Directional OTDR Measurement in a Hole-Assisted Fiber
Bi-Directional OTDR Measurement Fiber Hole-Assisted
2015/5/18
A novel analyzing model of bi-direction OTDR measurement in a hole-assisted fiber (HAF) is proposed. Using this model, both information on the air-hole structure and air-hole surface roughness in a HA...
Quantum Blackbox Model for Electro-Optical Phase Modulation
Phase Modulation Quantum optics
2015/6/4
We present, for the first time, a blackbox model characterizing the quantum optical phase modulation operation in terms of a unitary scattering operator which excludes the unphysical negative frequenc...
Novel Model of Thermal Conductivity for Optical Materials
Laser materials Thermal conductivity Thermal diffusivity
2009/6/1
We have proposed a novel model of thermal conductivity in various optical materials. This numerical model for thermal conductivity requires one material parameter for isovolumic specific heat and two ...
