Extra-terrestrial Adjustment Matching Orientation Processing
2015/12/17
The pushbroom scanner HRSC (High Resolution Stereo Camera) onboard the European Mars Express mission is orbiting the planet Mars since January 2004 and delivers stereoscopic imagery with five panchrom...
Application of Robust Regression for Exterior Orientation of Video Images
Orientation Video Adjustment Tracking Bundle Exterior Algorithms
2015/12/9
Nowadays, the 3-D measurement system using the video image sequences has been used in many fields, for example the vision sensor for machine control or the measurement technique of city area for GIS o...
Semi-Automatic Orientation of Images With Respect to a Point Cloud System
Adjustment automation calibration detection matching orientation programming
2015/12/8
This paper presents the results of a master thesis in which it was tried to orient a set of images of an object to a point cloud of the same object. As test object the “Semper Sternwarte” in Zürich wa...
Interpretation Terrestrial Images of Urban Scenes Using Discriminative Random Fields
Markov random fi eld parameter learning pseudo-likelihood man-made structure detection
2015/12/4
We investigate Discriminative Random Fields (DRF) which provide a principled approach for combining local discriminative classifiers that allow the use of arbitrary overlapping features, with ad...

Three-Line Matching DEM/DTM Georeferencing Orthorectification Accuracy
2015/11/24
This paper presents a methodology of image orientation and DEM extraction from ALOS-PRISM stereopairs without the use of GCPs. It uses the approximate geo-location information derived from the sensor ...
Camera Station Based Combiner Adjustment of Multi-Images
Adjustment Image Orientation Rigorous Model Exterior Elements Collinear Equation Lack Control Points
2015/11/23
Orientation and rectification of remote sensing imagery is one of the most important tasks for imagery processing, remote sensing imagery data transformed to specific coordinate system and with coordi...
Elevation-Controlled Block Adjustment for Weakly Convergent Satellite Images
Orientation orthorectification georeferencing bundle adjustment rational function model
2015/11/23
In order to acquire the largest possible coverage for environmental monitoring, small overlapping for satellite images is often the case. Hence, the traditional 3-D bundle adjustment as used in photog...
accuracy analysis on large blocks of high resolution images
QuickBird Scene Orientation Block Adjustment Quaternion ephemeris Rational Polynomial Coefficients
2015/9/1
A large block of QuickBird Basic Imagery has been analyzed for optimal control distribution and scene ties. This has been done by three dimensional adjustment of a block of Basic Imagery using satelli...
Unpaved roads are one of the most relevant causes of erosion process in rural regions. Locating unpaved roads in low-resolution
satellite images is not a trivial task. Although they have the spectra...
