Conecpt,Principle and Implementation of Seamless Stereo Orthimage Database

The idea and concept of the seamless stereo orthoimage database in a continuous block area is put forward.The principle and implementation of stereo orthoimage database are presented.Based on stereovision of human's eyes,the main idea of seamless stereo orthoimage database is to generate a seamless digital orthophoto quadrangles(DOQ) database from DEM and odd photos and generate additionally a digital stereo orthophoto partner(DSP) from DEM and even photos,and a large area 3D virtual landscape environment can be formed without y-parallax.The database is called seamless stereo orthoimage database formed by DOQ and DSP together.In such environment,the 3D measurement and analysis can be done under the interface of normal GIS or CAD systems without complex DPW.The 3D objects,such as houses,trees,cloverleaf junctions,geologic ruptures,and so on,which are not acquired during data acquisition at DPW,can be measured by end user himself.The case study and some potential applications are given at last
