A COMPARATIVE STUDY AMONG THREE REGISTRATION ALGORITHMS: PERFORMANCE, QUALITY ASSURANCE AND ACCURACY
Accuracy Automation Least Squares Registration'Terrestrial Laser Scanning
2019/3/4
A critical task in every terrestrial laser scanning project is the transformation (addressed to as registration or alignment) of multiple point clouds into a common reference system. Even though this ...
Digital Terrain Models (DTM) are frequently used to make important decisions. In order to judge these decisions DTM quality must
be known. The quality of a DTM consists of several components like pre...
FACTORS AFFECTING THE QUALITY OF DTM GENERATION IN FORESTED AREAS
Digital Terrain Model DTM airborne laser scanning ALS algorithms quality
2015/8/13
Airborne laser scanning (ALS) has become an established tool for acquiring digital terrain models (DTM) in forested areas. Even
though, there have been several empirical studies on DTM quality with l...
HIGH QUALITY DEMS FOR GLACIER MONITORING –IMAGE MATCHING VERSUS LASER SCANNING
Glaciology Matching Laser Scanning DEM/DTM Comparison
2015/7/29
Glacier monitoring is of great importance since glaciers are influencing essential areas of life like water supply, energy production,
flood protection and tourism. Furthermore, the variation of gla...
Experimental investigation of the quality of transmission in transparent mesh networks with mixed fiber types
Fiber optics communications Fiber optics links subsystems
2015/6/4
We experimentally investigate the quality of transmission in mesh networks relying on various fiber types. We show that the quality of transmission can be evaluated accurately using the weighted nonli...
High Quality and Efficient QPM-LiNbO 3 Wavelength Converter Integrated With 0.78/1.56-μ μm Wavelength Multiplexer
High Quality Efficient QPM-LiNbO Wavelength Converter Integrated Wavelength Multiplexer
2015/7/15
We achieved the first integration of a QPM wavelength converter with an MMI multiplexer by using a direct-bonded LiNbO 3 ridge waveguide. We successfully demonstrated high quality grouped wavelength c...
High-Quality Poly-Si Crystallization Technology Based on Laser-Induced Melting and Resolidification Dynamics of Si Thin Films
Poly-Si TFT Laser crystallization Lateral crystal growth
2009/6/9
The liquid-solid interface motion and the temperature history of thin Si films during short pulse (< 30 ns) excimer laser annealing are observed by in-situ diagnostics. Substantial supercooling (> 200...
Fabrication of High Quality Poly-Si TFTs by Using Ar-Laser Irradiated Sputter-Si Films
Polycrystalline Si Sputtering Ar-laser
2009/6/9
Precursor a-Si films are deposited by RF planar magnetron sputtering in argon gas at 200 °C substrate temperature. Properties of the a-Si films have large dependences on sputtering gas pressure. Sheet...
Characteristics of a High-Power Diode-Directly-Pumped Yb:YAG Laser with High Beam Quality
Diode-pumped Yb:YAG Continuous wave
2009/6/1
We have demonstrated and analyzed a high-power continuous-wave (cw) Yb:YAG laser directly pumped into the upper lasing level by a fiber-coupled laser diode with a center wavelength of 969 nm. The outp...
Effect of In content of the buffer layer on crystalline quality and electrical property of In0.82Ga0.18As/InP grown by LP-MOCVD
In0.82Ga0.18As Buffer layer MOCVD
2011/12/15
The In0.82Ga0.18As grown on InP (1 0 0) substrates by low pressure metalorganic chemical vapor deposition (LP-MOCVD) with twostep growth method was investigated. It was analyzed that the effect of In ...
