ROBUST VISION-BASED POSE ESTIMATION ALGORITHM FOR AN UAV WITH KNOWN GRAVITY VECTOR
UAV machine vision external orientation estimation motion capture system
2016/11/11
Accurate estimation of camera external orientation with respect to a known object is one of the central problems in photogrammetry and computer vision. In recent years this problem is gaining an incre...
Looking inside the Panarea Island (Aeolian Archipelago, Italy) by gravity and magnetic data
Magnetism Gravity Panarea Island Hydrothermal system
2015/9/1
In this paper we show and discuss the results of gravity and magnetic surveys of Panarea Island and its archipelago. The most recent volcanic manifestation occurred in November 2002 with a shallow sub...
STUDY OF SATELLITE GRAVITY OVER THE SUMATRAN EARTHQUAKE REGION
SATELLITE ALTIMETRY GEOSAT GM ERS-1
2015/8/31
The devastating earthquake (and the corresponding tsunami) that struck the Indian Ocean
near Sumatra (Indonesia) on 26 December, 2004 was extremely powerful. In the present
study, a very high resolu...
The Contributions of Abyssal Hill Morphology and Noise to Altimetric Gravity Fabric
Noise Altimetric Gravity Fabric
2015/7/29
Earth's deep seafloor is, for the most part, a vast, unexplored terrain. Only a miniscule fraction has ever been observed directly, using deep submersibles and remotely operated vehicles. Most of our ...
On Improved Gravity Modeling Supporting Direct Georeferencing of Multisensor Systems
GPS/INS navigation calibration
2015/7/15
Typically, inertial navigation systems assume the gravity field to be normal (ellipsoidal), meaning that the deflections of the vertical
(DOV) are ignored in the gravity compensation procedure. This ...
Estimation of regional mass anomalies from Gravity Recovery and Climate Experiment (GRACE) over Himalayan region
Water Equivalent height (WEH) GRACE Himalaya
2014/12/15
Time-variable gravity changes are caused by a combination of postglacial rebound, redistribution of water and snow/ice on land and as well as in the ocean. The Gravity Recovery and Climate Experiment ...
Spatial analysis from remotely sensed observations of Congo basin of East African high Land to drain water using gravity for sustainable management of low laying Chad basin of Central Africa
Analysis Combination Environment land Management Observations Remote sensing Sustainable
2014/12/4
The Chad basin which covers an area of about 2.4 million kilometer square is one of the largest drainage basins in Africa in the centre of Lake Chad .This basin was formed as a result of rifting and d...
Measuring Public School Competition from Private Schools: A Gravity-Based Index
Public School Gravity-Based Index Market Competition Education
2013/3/5
This research develops a gravity-based index of public school competition from private schools within local markets. Proponents of educational reform often call for policies to increase competition be...
