Investigation of geometrical self-calibration adjustment model of satellite sensors

In this paper, CCD array displacement and rotation model, focal length displacement model and optical distortion model were analyzed for line-array CCD sensor of high resolution satellites. An integrated interior self-calibration model was then proposed. Applying piecewise polynomial interpolation model, contents of exterior parameters to be calibrated were analyzed. Based on collinearity equation, a self-calibration bundle block adjustment model was constructed and relative solution method was given. Through SPOT5 simulation datasets, block adjustment experiments were done and the experimental results verified the feasibility of the solution model. © 2012 Springer-Verlag Berlin Heidelberg.
