On 3D change detection with multi-source spatial data

XIA Song ①②,LI De-ren ②,WU Zhao-cong ②(①Information School,Zhongnan University of Economics & Law,Wuhan 430060,China;②School of Remote Sensing & Information Engineering,Wuhan University,Wuhan 430079,China)  
In this paper,a technical framework of 3D change detection based on existing Digital Elevation Model(DEM),Digital Ortho image(DOM),Digital Line Graph(DLG)and new stereo imagery is presented.And many key techniques such as VLL matching,multi-scale DEM,self-adapted matching window and thresholds for the framework are discussed and investigated deeply.The idea and method are verified elementarily in our experiments.
