Abstract
A computer implemented method of adjusting original rational polynomial coefficients of an RPC model for an image acquired by an image sensor comprising providing rational polynomial coefficients associated with the image calculating a pseudo position and attitude angles for the sensor using the original coefficients providing at least one ground control point associated with the image adjusting the pseudo position and attitude angles using the at least one ground control point; and adjusting the original coefficients for the image using the adjusted pseudo position and attitude angles.
