Camera Estimation for Orbiting Pushbrooms

Several space borne cameras use push broom scanning to acquire imagery Traditionally mod eling and analyzing these sensors has been computation ally intensive due to the motion of the orbiting satellite with respect to the rotating earth and the non linearity of the mathematical model involving orbital dynamics A new technique for mapping a D point to its cor responding image point that leads to fast convergence is described Besides computational e ciency experi mental results also con rm the accuracy of the model in mapping D points to their corresponding D points
