Abstract  

For flight under harsh conditions,aiming at the internal distortion remained after the high\|resolution airbornelinear array pushbroom images geometric correction based on the POS data,the method of geometric rectification of High\|Resolution Airborne Linear Array pushbroom Image based the point and line feature is studied,and the strong relativity in computing the exterior orientation elements caused by the small image pieces is analyzed.The method that line elements and angle elements are computed separately which is used for the solution of exterior orientation.The results of experiments indicated that the method is feasible for geometric distortion in Airborne Linear Array pushbroom Image casued by the measurement error of the elements in POS data.

Key words:  High resolution      Airborne Linear Array pushbroom Image      Geometric rectification      Line feature
