STEREO IMAGE DENSE MATCHING BY INTEGRATING SIFT AND SGM ALGORITHM
Stereo Matching Semi-Global Matching SIFT, Dense Matching Disparity Estimation Census
2018/5/17
Semi-global matching(SGM) performs the dynamic programming by treating the different path directions equally. It does not consider the impact of different path directions on cost aggregation, and with...
DETECTION AND 3D MODELLING OF VEHICLES FROM TERRESTRIAL STEREO IMAGE PAIRS
Object Detection Stereo Images 3D Reconstruction 3D Modelling Active Shape Model
2017/7/13
The detection and pose estimation of vehicles plays an important role for automated and autonomous moving objects e.g. in autonomous driving environments. We tackle that problem on the basis of street...
REFINEMENT OF STEREO IMAGE ANALYSIS USING PHOTOMETRIC SHAPE RECOVERY AS AN ALTERNATIVE TO BUNDLE ADJUSTMENT
Stereo Image Analysis Shape from Shading Bundle Adjustment DEM 67P/Churyumov-Gerasimenko
2016/11/8
Topographic mapping, e.g. the generation of Digital Elevation Models (DEM), is of general interest to the remote sensing community and scientific research. Commonly, photogrammetric methods, e.g. ster...
An Accuracy Assessment of CARTOSAT-1 Stereo Image Data-Derived Digital Elevation Models: A Case Study of the Drum Mountains, Utah
Cartosat-1 DEM NED ASTER DOQQ Vertical Horizontal Accuracy
2015/11/24
This study evaluates the accuracy of digital elevation models (DEMs) produced from Cartosat-1 data. The Cartosat-1 satellite, launched by the Indian Space Research Organization (ISRO) in May 2005, car...
A Hybrid Method for Stereo Image Matching
Photogrammetry Matching Feature Extraction DEM/DTM
2015/11/23
The accuracy of the 3D models of the Earth surface based on stereoscopic image pairs depends on the accuracy of corresponding points located in both images. Area-based automatic image matching combine...
STEREO IMAGE MATCHING USING ROBUST ESTIMATION AND IMAGE ANALYSIS TECHNIQUES FOR DEM GENERATION
Image matching computer vision image understanding DEM
2014/12/31
Digital Elevation Models (DEM) produced by digital photogrammetry workstations are often used as a component in complex Geographic Information Systems (GIS) modeling. Since the accuracy of GIS databas...
3D-OBJECT DETECTION METHOD BASED ON THE STEREO IMAGE TRANSFORMATION TO THE COMMON OBSERVATION POINT
algorithms stereoimages processing 3D object detection computer vision
2014/12/31
The method of 3D-object detection by stereo image processing is considered where object is situated on the smooth surface. Stereo image is obtained by passive sensor such as TV-camera, IR-camera and s...
