A Region-based Matching Approach for 3D-Roof Reconstruction from HR Satellite Stereo Pairs
This study is a part of a global project on urban scenes interpretation using high resolution satellite images. Actually, the research is focused on buildings and roads are used to delineate zones of interest. This study details automatic reconstruction of 3D facets using a region matching approach based on hierarchical segmentation of images. The novelty consists in dedicating algorithms to sa...
متن کاملOrthorectification and Digital Elevation Model (DEM) Generation Using Cartosat-1 Satellite Stereo Pair in Himalayan Terrain
High resolution data have high relief displacement in hilly terrains. Development of Digital Elevation model helps to assess bio resources more accurately in such terrains. While estimating bio resources in the Himalayan hilly terrain using multispectral LISS-III data of 23 m spatial resolution, the need for orthorectifcation of satellite data was necessary to correct for spatial distances due ...
متن کاملStereo analysis, DEM extraction and orthorectification of CORONA satellite imagery: archaeological applications from the Near East
CORONA satellite imagery, preserving an account of the earth’s surface from 40 years ago, is a most important archaeological survey tool and we have often sung its praises. Here the authors use new procedures to extend the competence and revelations of CORONA even further. Stereo pairs derived from images taken from fore and aft of the satellite give three dimensional images of landscapes and e...
متن کاملExtraction of Depth Elevation Model (DEM) from High Resolution Satellite Imagery using Shape from Shading Approach
Shading information in satellite imagery will give user an immediate appreciation for the surface topography. In this paper, an attempt has been made to reconstruct 3D shape or Depth elevation model (DEM) of satellite imagery using Shape from Shading approach. Three widely used shape from shading algorithms – Pentland‟s Linear approach, Lee and Rosenfeld‟s approach and Horn‟s approach were used...
متن کاملLocalization based on vision using stereo System and SIFT features
The traditional method uses the GPS signal to determine the location of a vehicle or Mobile Robot, but these methods sometimes fail to determine the exact position of the object especially in urban areas, or inside buildings. It fails to determine the position for multiple reasons such as the multi-fading path, obstacles, rain, and snow which all have an effect on the signal of the GPS. The dev...
