摘要：OLR is engaged in several stereo scanner projects(MEOSS on Indian Remote Sensing mission IRS··1 E,MOMS-02 on German shuttle mission 02, HRSC andWAOSS cameras on Russian Mars mission). Besidesfabricating the flinht hardware for MEOSS camera OLRdeveloped a software package for the evaluation ofstereoscopic scanner data consisting of the followingmain SUbsystems:Image matching software for automatically locatinglarge numbers of conjugate points in 3--line stereoscanner imagery. It is based on areal matching inimage pyramids and subsequent local least squaresmatching for subpixel positioning.Photogrammetric adjustment software is used to derivedigital elevation models and exterior orientationparameters. This combined point determination softwareis mainly based on collinearity equations for conjugateand ground control points. Further it allows forthe constraining of the exterior orientation of the cameraby ~Jiven flight path and attitude data and by GauSMarkovstatistical processes.The paper reports on the successful application of thesoftware to air-borne data taken with the satellite rnodelof the MEOSS camera, including a comparison to analready existing OEM. Empirical and theoretical errorsare given for various numbers of ground control points.Keywords: 3-line stereo scanners, image rnatching,photograrnrnetry, di~lital elevation models
