Research on the Trajectory Model for ZY-3
The new generation Chinese high-resolution three-line stereo-mapping satellite Ziyuan 3 (ZY-3) is equipped with three sensors (nadir, backward, and forward views). Its objective is to manufacture the 1 : 50000 topographic map and revise and update the 1 : 25000 topographic map. For the push-broom satellite, the interpolation accuracy of orbit and attitude determines directly the satellite's ste...
متن کاملResearch on High-precision Geometric Positioning of ZY-3
This paper established strict image-object relationship model of ZY-3,and analyzed orbital data and attitude data statistically. It did camera geometric calibration using high-precision artificial target. Internal geometric correction of the original satellite images, eliminating the interior orientation parameters such as non-uniform transition, transition of the integration time and attitude ...
متن کاملResearch on the Dom Update Based on Zy-3 Satellite Images and Image Control Points Database
It is proposed a new method that quick updating 50,000 scale DOM based on the ZY-3 satellite images and Images Control Points Database obtained from the existing 10,000 scale DOM and DEM. The construction of GCP Image Database is introduced, and the fast searching GCP Image Chips from the database is proposed. And the auto-matching and elimination of error points are presented. What’s more, exp...
