摘要:An empirical model is proposed to solve the problem that exists in in-orbit calibration method for TDICCD camera in this paper. The method brings in the line frequency normalization and virtual image stitching from TDICCD images to the pre-processing procedure, which makes the virtual mosaic images has the same characteristics as the regular Linear push-broom CCD images, therefore the interior and external calibration is possible to realize. The experimental results show that the empirical model of TDICCD camera used in in-orbit calibration can improve precision and reduce the geometric distortion of images. Moreover, the geometric quality of images is enhanced. The method presented in this paper can be used to generate high-precision geometric rectification production.
