ESTIMATION OF STAND HEIGHT AND FOREST VOLUME USING HIGH RESOLUTION STEREO PHOTOGRAPHY AND FOREST TYPE MAP
Stand Height Forest Volume normalized DSM Aerial Photo
2016/11/30
Traditional field methods for measuring tree heights are often too costly and time consuming. An alternative remote sensing approach is to measure tree heights from digital stereo photographs which is...
ENHANCEMENT STRATEGIES FOR FRAME-TO-FRAME UAS STEREO VISUAL ODOMETRY
Unmanned Aircraft Systems Stereo Visual Odometry Pose Estimation Drift Reduction
2016/7/27
Autonomous navigation of indoor unmanned aircraft systems (UAS) requires accurate pose estimations usually obtained from indirect measurements. Navigation based on inertial measurement units (IMU) is ...
Generation of COARSE 3D Models of Urban Areas from High Resolution Stereo Satellite Image
digital terrain model surface modelling stereo image high resolution
2015/11/23
With the emergence of more and more satellites delivering very high resolution (VHR) imagery with ground sampling distances in the range of one meter or below the generation of three dimensional urban...
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...
CARTOSAT-1 STEREO ORTHOKIT DATA EVALUATION
Cartosat-1 IRS P5 C-SAP Orthoimagery DEM Data Evaluation
2015/9/17
The results of Cartosat-1 imagery investigation as part of ISPRS-ISRO Cartosat-1 Scientific Assessment Programme (C-SAP) are presented. Different images orientation methods have been tested; the recom...
DIRECT GEOREFERENCING OF DIGITAL CAMERA IMAGES FOR STEREO PLOTTING
direct georeferencing digital aerial camera UltraCamD GPS/IMU calibration
2015/9/17
In the years of 2004 to 2006, the Portuguese authority for forestry, the Direcção Geral dos Recursos Florestais (DGRF) ordered a digital photo flight over the whole country. The images, acqu...
3D zebra-crossing reconstruction from stereo rig images of a ground-based mobile mapping system
Zebra-crossing detection Pedestrain crossing Road-mark 3D Reconstruction
2015/8/24
Zebra-crossings are very specific road features that are less generalized when imaged at different scales. We aim to use zebra-crossings as control objects for georeferencing the images provided...
In this paper, we propose a new scan line optimization method for matching the triplet of images. In the present paper, the triplets are initially matched using an area based local method. The cost is...
A supervised method for object-based 3D building change detection on aerial stereo images
Change detection Aerial images Digital Surface Models Support Vector Machine
2014/9/9
There is a great demand for studying the changes of buildings over time. The current trend for building change detection combines the orthophoto and DSM (Digital Surface Models). The pixel-based chang...
