Stereoscopic evaluation of combined stereoscopic (along-track) and multispectral data of the MOMS-02 sensor

摘要

Abstract: The modular optoelectronic multispectral scanner (MOMS-02) has been flown successfully on the German space shuttle mission D2 in April/May 1993. Its outstanding feature is along-track stereoscopic imaging. The imaging mode 3 is combining the two off-nadir panchromatic channels with two nadir-looking color channels (red and near infrared). The ground pixel size is 13.5 $MUL 13.5 m$+2$/, and the base to height ratio is about 0.8. The paper reports on first results of the photogrammetric evaluation of MOMS-02 mode 3 data on Mexico (D2 orbit 82). The evaluation process is subdivided into three major steps: automatic image matching to derive large numbers of conjugate points, performed with software developed at DLR for the common Indian-German stereo scanner project MEOSS. Combined point determination for the reconstruction of the exterior orientation and the calculation of the ground coordinates of conjugate points using bundle block adjustment software CLIC developed at Technical University Munich. Generation of a digital terrain model from all conjugate points, which previously are transformed into the object space by multiple forward intersection. A report on the results achieved is given. !11
