2.7. Summary
This chapter introduces geometric processing and positioning techniques for satellite remote sensing imagery, including systematic error calibration, geometric rectification, geometric registration, DEM generation, and DOM generation. The core technique is the establishment of a suitable geometric processing model for satellite imagery and the precise solution of all unknown parameters of the model.
In actual applications, users can select a suitable geometric processing model to implement the geometric processing of satellite imagery according to different requirements. When the accuracy requirement of the image products is not high, the geometric processing model whose parameters can be solved easily and whose computation demand ...
