COMPARISON WITH ACCURACY OF TERRESTRIAL LASER SCANNER BY USING POINT CLOUD ALIGNED WITH SHAPE MATCHING AND BEST FITTING METHODS
laser scanning time of flight phase shift shape matching natural distributions Ostia
2019/3/4
Recently operation systems of laser scanning have been obviously improved; for instance shape matching has been equipped with software on a post processing stage so measurement without any targets is ...
MULTIGRID CELL SHAPE EVALUATION IN DTM FILTERING OF MOBILE LIDAR POINT CLOUDS
Point cloud Mobile LiDAR Digital terrain models Filtering Delaunay triangulation
2018/11/9
The georeferenced information acquisition for large scales digital terrain models generation is usually a rather time-consuming and costly process. The use of point clouds gathered by mobile LiDAR sys...
USAGE OF MULTIPLE LIDAR SENSORS ON A MOBILE SYSTEM FOR THE DETECTION OF PERSONS WITH IMPLICIT SHAPE MODELS
LiDAR Mobile Laser scanning MLS Person Detection Classification
2018/6/4
The focus of this paper is the processing of data from multiple LiDAR (light detection and ranging) sensors for the purpose of detecting persons in that data. Many LiDAR sensors (e.g., laser scanners)...
A NOVEL 3D CITY MODELLING APPROACH FOR SATELLITE STEREO DATA USING 3D ACTIVE SHAPE MODELS ON DSMS
Building Modelling City DSM/DTM
2014/4/28
Since remote sensing provides new sensors and techniques to accumulate stereo data on urban regions, three-dimensional (3D) repre- sentation of these regions gained much interest for various applicati...
System Requirements for WSS Filter Shape in Cascaded ROADM Networks
Optical switching devices All-optical networks Fiber optics optical communications
2015/6/8
We describe the impact of passband shape and random center frequency variations on the bandwidth narrowing caused by successive filtering in concatenated wavelength-selective switches. Passband flatne...
In-Service Chromatic Dispersion and Pass-Band Shape Measurements for Light Path with Modulated ASE Source
Networks wavelength routing Fiber measurement
2015/6/5
A tunable modulated broadband source and narrow-bandwidth filter are used to measure chromatic dispersion, group-delay ripple, and pass-band shape of DWDM-network light paths. This new method is simpl...
Enhancement of 43Gb/s DPSK Transmission Though 66 Wavelength Selective Switches Using Adaptive Channel Shape Optimization
Wavelength Selective Switches Adaptive Channel Shape Optimization
2015/7/17
A 43Gb/s DPSK format data transmission is demonstrated through 66 Wavelength Selective Switches (WSSes). By optimizing the channel shape of one of the WSSes, the transmission distance was increased fr...
Tunable Birefringent Phase-Shift Induced in Fiber Bragg Grating by a Shape Memory Alloy Ferrule
Tunable Birefringent Phase-Shift Induced Fiber Bragg Grating Shape Memory Alloy Ferrule
2015/7/15
We present a new method to induce low loss tunable birefringent phase shifts in fiber Bragg grating by applying mechanical stresses at precise locations along the FBG with a specially designed shape m...
A Nd doped Multimode-Fiber-Laser with D-Shape Large Clad under Quasi-Solar-Pumping
Solar-pumped solid-state laser Neodymium Fiber laser
2009/6/8
We observed laser oscillation for a multimode Nd-doped fiber laser with D-shaped cladding under quasi-solar-pumping simulated by an intense halogen lamp with a color temperature of 5,600 Kelvin. The f...
A perspective shape-from-shading method using fast sweeping numerical scheme
shape-from-shading reflectance map viscosity solution
2011/5/5
Shape-from-shading (SFS) is an approach of 3-D shape reconstruction from only one image. A new perspective SFS method is proposed in this paper. Firstly, a reflectance map equation under perspective p...
