PROBLEMS AND LIMITATIONS OF SATELLITE IMAGE ORIENTATION FOR DETERMINATION OF HEIGHT MODELS
ZY3 WorldView-2 Pleiades Cartosat-1 systematic errors
2017/7/12
The usual satellite image orientation is based on bias corrected rational polynomial coefficients (RPC). The RPC are describing the direct sensor orientation of the satellite images. The locations of ...
HIERARCHICAL STRUCTURE FROM MOTION COMBINING GLOBAL IMAGE ORIENTATION AND STRUCTURELESS BUNDLE ADJUSTMENT
Structure from Motion Global Image Orientation Structureless Bundle Adjustment Hierarchical Image Orientation
2017/7/13
Global image orientation techniques aim at estimating camera rotations and positions for a whole set of images simultaneously. One of the main arguments for these procedures is an improved robustness ...

IMAGE ORIENTATION FOR INTERACTIVE TOURS OF VIRTUALLY-MODELED SITES
utomated Orientation Ground-level Imagery VR Sites
2015/8/7
This paper addresses the issue of image orientation for interactive tours. We consider situations where image sequences are captured
in an urban site for which a virtual-model is already available. ...

2015/7/14
Advances in sensor technology and computing capabilities and modalities are revolutionizing close-range image collection and
analysis for geospatial applications. These advances create the need for n...
IMAGE ORIENTATION BY COMBINED BUNDLE ADJUSTMENT WITH FIXED IMAGERIES
Photogrammetry DEM/DTM Orthoimage Exterior Orientation Adjustment Accuracy
2015/6/1
According to self-calibration bundle block adjustment, a mathematical model which solutes exterior orientation elements of the new imageries by using fixed imageries in the same area is set up at firs...
IMAGE ORIENTATION BY COMBINED (A)AT WITH GPS AND IMU
GPS IMU Direct Sensor Orientation Integrated Sensor Orientation
2015/5/12
During recent years the direct sensor orientation with GPS and IMU has gained popularity. These systems allow the determination of
all exterior orientation elements without using ground control point...
FUNDAMENTAL PRINCIPLES OF IMAGE ORIENTATION USING ORTHOGONAL PROJECTION MODEL
orthogonal projection orientation model
2015/3/24
The central perspective model is generally used in photogrammetry because of the high reliability, but it has a weak point
that the initial values of orientation parameters are necessary due to the n...

2015/3/24
In this paper we present a new method for single image orientation using an orthographic drawing or map of the scene.
Environments which are dominated by man made objects, such as industrial faciliti...
IMAGE ORIENTATION AND OBJECT RECONSTRUCTION VIA POINTS ON COUNTOURS
Surface reconstruction Orientation Mathematical models
2015/1/6
The main task in photogrammetry is the reconstruction of three-dimensional objects - size, shape, position or geometric distance - from analog or digital images. In a first step the camera position an...
This article addresses a methodology and the experience gained on automatic exterior image orientation by using current information existing in GIS database. The proposed approach automatically extrac...
STATISTICAL TESTINGS FOR DETERMINING SIGNIFICANT SAR-IMAGE ORIENTATION PARAMETERS
