Accurate geometric calibration of large resolution digital aerial survey camera

By fixing large resolution digital aerial survey camera inside height axis of two-dimension inner orientation instrument, turning measure frame to make image point object of parallel light pipe image on CCD surface, the inner orientation element and distortion value of large resolution digital aerial survey camera are obtained by means of combining corresponding computation formula and measure control software. And the problem of bigger view field and not easy calibration of large resolution digital aerial survey camera is solved. Calibration experiment is implemented and result demonstrates that the method is feasible.
