In a good stereo pair, humans readily fuse the two images and perceive a 3-D scene. The relief may be exaggerated, but our brains are comfortable with the presentation. Similarly, stereo correlation algorithms used for automatic terrain extraction operate nicely on good stereo pairs. ]]> http://www.socetgxp.com/gxpmosaic/research-and-development/stereo-image-matching-breakthroughs-in-automated-change-detection/feed 0 http://www.socetgxp.com/gxpmosaic/research-and-development/simultaneous-generation-of-dsm-and-dem http://www.socetgxp.com/gxpmosaic/research-and-development/simultaneous-generation-of-dsm-and-dem#comments Mon, 01 Dec 2008 19:00:57 +0000 cgordon http://www.socetset.com/gxpmosaic/?p=962
Submitted by Dr. Bingcai Zhang, Engineering Fellow NGATE can generate an accurate and dense digital surface model (DSM) that includes buildings, houses, trees, etc. from stereo images. In many applications, a digital elevation model (DEM) or bare-earth model is required. Transforming a DSM to a DEM is an expensive manual operation. In SOCET SET® v5.4.1, a [...]]]> http://www.socetgxp.com/gxpmosaic/research-and-development/simultaneous-generation-of-dsm-and-dem/feed 0 http://www.socetgxp.com/gxpmosaic/research-and-development/next-generation-automatic-terrain-extraction-ngate http://www.socetgxp.com/gxpmosaic/research-and-development/next-generation-automatic-terrain-extraction-ngate#comments Sat, 02 Sep 2006 01:00:03 +0000 gxpwebadmin http://www.socetset.com/gxpmosaic/?p=803
With MSN® Virtual Earth™ and Google™ Earth, 3D geospatial data is finding its way into daily life. A digital terrain model (DTM) is one of the most important 3D geospatial data types. One of the key automation technologies in softcopy photogrammetry is to generate a DTM automatically. The most reliable and widely used algorithm for [...]]]> http://www.socetgxp.com/gxpmosaic/research-and-development/next-generation-automatic-terrain-extraction-ngate/feed 0
