GLOBAL REGISTRATION OF KINECT POINT CLOUDS USING AUGMENTED EXTENDED INFORMATION FILTER AND MULTIPLE FEATURES
Global registration Kinect Augmented extended Information filter Point cloud fitting Indoor mapping
2016/10/14
Because the Infra-Red (IR) Kinect sensor only provides accurate depths up to 5 m for a limited field of view (60°), the problem of registration error accumulation becomes inevitable in indoor ma...
MARINE GEOID UNDULATION ASSESSMENT OVER SOUTH CHINA SEA USING GLOBAL GEOPOTENTIAL MODELS AND AIRBORNE GRAVITY DATA
Global Geopotential Model Geoid Undulations Airborne Gravity Gravity Missions
2016/10/14
Global geopotential models (GGMs) are vital in computing global geoid undulations heights. Based on the ellipsoidal height by Global Navigation Satellite System (GNSS) observations, the accurate ortho...

Results derived from analysing the ionosphere response to faint and bright solar flares are presented. The analysis used technology of a global detection of ionospheric effects from solar flares as de...
GPS detection of the instantaneous response of the global ionosphere to strong magnetic storms with sudden commencement
Magnetic field strenght ionospheric disturbances
2015/9/25
Using a new technology for global GPS detection of ionospheric disturbances, GLOBDET, it has been established that a drastic increase in the time derivative of the magnetic field strength during magne...
A high-order conservative collocation scheme and its application to global shallow-water equations
conservative collocation scheme global shallow-water equations
2015/3/5
In this paper, an efficient and conservative collocation method is proposed and used to develop a global
shallow-water model. Being a nodal type high-order scheme,
the present method solves th...
Application of a global nonhydrostatic model with a stretched-grid system to regional aerosol simulations around Japan
stretched-grid system Japan
2015/3/5
An aerosol-coupled global nonhydrostatic model
with a stretched-grid system has been developed. Circulations over the global and target domains are simulated with
a single model, which includes @...
Can the Earth’s harmonic spectrum be derived directly from the stochastic inversion of global travel-time data?
Earthquake GPS Historical seismology Ionosphere Irpinia
2015/8/18
A set of seismic observations which all sample the same structure in the same way should have zero variance. This is naturally the case if all sources are in the same place, and the data are recorded ...
The MgSiO3 system at high pressure: Thermodynamic properties of perovskite, postperovskite, and melt from global inversion of shock and static compression data
perovskite postperovskite melt
2014/4/8
We present new equation-of-state (EoS) data acquired by shock loading to pressures
up to 245 GPa on both low-density samples (MgSiO3
glass) and high-density,
