The availability of new radar spaceborne sensors offers new interesting potentialities for the geomatics application: spatial and temporal change detection, generation of Digital Elevation Model(DEM) ...
There was always a speed/accuracy challenge in photogrammetric mapping process, including feature detection and matching. Most of the researches have improved algorithm's speed with simplifications or...
Generating accurate elevation data from satellite images is a prerequisite step for applications that involve disaster forecasting and management using GIS platforms. In this respect, the high resolut...
The use of airborne video data is gaining increasingly attention in the photogrammetric community. This interest is driven by theavailability of low-cost sensor platforms like UAV and low-cost sensors...
Automatic determination of three dimensional information from digital images is a fundamental problem in digital photogrammetry and computer vision. The hardest part of the problem is finding conjugat...
This paper discusses issues for matching point features in structure from motion, i.e., pose estimation and 3D reconstruction. As ourbuilding block are image triplets for which matches can be checked ...
Feature matching is to find the pair-wise corresponding features in the reference and sensed images. The features can be an edge, a corner, an end point, a line or a curve, etc. Image matching as the ...
High-resolution satellite images (HRSI) at sub-5m footprint such as IKONOS, IRS-P5 (CartoSat-1) and SPOT-5 HRG/HRS images are becoming increasingly available to the earth observation community and the...
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...
This paper presents a method for semi-automatic 3D positioning of tree tops that can be used for obtaining tree maps of the photovisible trees and tree heights. Such spatio-temporal, detailed informat...
In the frame of our long term, interdisciplinary Nasca/Palpa project, conducted in a close cooperation between our group and archaeologists from the German Archaeological Institute (DAI, KAAK Bonn), ...
This paper presents a method for semi-automatic 3D positioning of tree tops that can be used for obtaining tree maps of the photovisible trees and tree heights. Such spatio-temporal, detailed informat...
This paper proposes a new approach to image matching by epipolar constraint and local reliability constraint for Remote Sensing Image. We define a new measure of matching support according to the loc...
China’s first airborne SAR mapping system (CASMSAR) developed by Chinese Academy of Surveying and Mapping can acquire high-resolution and full polarimetric (HH, HV, VH and VV) Synthetic aperture radar...
Today, digital terrain models (DTMs) are used in many fields of science and practice. When modelling the earth’s surface it is necessary to make a clear distinction between terrain models, i.e. model...
