ESTIMATION OF THE ACCURACY OF THE SRTM TERRAIN MODEL ON THE AREA OF POLAND
SAR Interferometer DEM/DTM Reference Data Statistic Accuracy Analysis
2015/12/30
In order to determine the absolute accuracy of SRMT model on Polish area the research work has been performed on the basis of reference terrain profiles measured by GPS technique. The flat and hilly t...
Evaluation of Relative Pose Estimation Methods for Multi-Camera Setups
Camera motion estimation multi-view geometry relative orientation algorithm comparison
2015/12/8
The fully automatic and reliable calculation of the relative camera pose from image correspondences is one of the challenging tasks in photogrammetry and computer vision. The problem has not been solv...
Usually, filtering is performed in order to extract a ground surface from laser points obtained with the airborne laser scanner. It
mainly removes the laser points that were measured as trees surfac...
ON THE ESTIMATION OF PLANIMETRIC OFFSETS IN LASER ALTIMETRY DATA
Laser altimetry strip adjustment
2015/3/24
Offsets between overlapping strips of laser altimetry data serve as the input for strip adjustment procedures that estimate and
eliminate systematic errors in laser altimetry datasets. For a three-di...
AUTOMATIC POSE ESTIMATION OF IMAGERY USING FREE-FORM CONTROL LINEAR FEATURES
Data Fusion Linear Features
2015/3/24
Automatic Single Photo Resection (SPR) remains to be one of the challenging problems in digital photogrammetry. Visibility and
uniqueness of distinct control points in the input imagery limit robust...
CHARACTERIZING IMAGE QUALITY: BLIND ESTIMATION OF THE POINT SPREAD FUNCTION FROM A SINGLE IMAGE
Characterization of algorithms contrast sensitivity function (CSF)
2015/3/24
This paper describes a method for blind estimation of sharpness and resolving power from a single image. These measures
can be used to characterize images in the context of the performance of image a...
