摘要：An analytical positioning system for scanner remote sensing imageryusing a DTM for relief information has been developed. The fundamental geometricmodel in the system is a collinearity condition of scanner data.The system is presently being used practically--mainly for geothermal mappingof mountainous areas. Accuracy studies of the analytical positioning systemhave been carried out with experimental as well as practical MSS strip data.The test results show an accuracy of about 3 pixels in standard deviation ofresidual errors after exterior orientation of MSS strips. Conformity of theorientation polynomial model has been checked using the experimental MSSstrips. The results indicate that uncompensated pitching and/or aircraftground speed change are primary sources of the strip deformation. Adjustmentusing square sections MSS strips as a unit is most practical for better fittingof lower degree orientation polynomial models. Non-linear image distortionalong scan line, which disturbs the conformity of the collinearity modelwas observed in the film printed MSS data at the ground processing station.Comparative study of the film printed data and the direct digital conversiondata indicated the fact that the non-linear image distortion was introducedby the film printer, probably in the process of the scan angle correction.The residual errors in the exterior orientation were reduced substantially bycorrecting such non-linear image distortion. Preparation of DTM data stillremains the most time consuming and tedious work in the digital differentialrectification system. Further study and development are required in thisfield. Since relief information is given by DTM in this system, furtherutilization of the DTM related information is expected to produce more advancedprocessing of the MSS remote sensing data.
