Abstract
When the position of the perspective center and the attitude of the CCD camera on the exposing time is known,the coordinates of ground points can be calculated from the images gotten from TSL CCD.The method for fitting the position of the camera center and the attitude functions is basic for image georeferencing.According to the character of the data given by GPS/INS,a semi-parametric method is proposed.Simulated calculation indicates that this method can reduce the systematic errors significantly.
