Abstract

TH-1 satellite’s administer sends RPC to the users as the main assist data so as to hide the sensor’s technique parameters. This paper introduces the methods of stereo positioning based on the RPC model, and analyses the key problem of the obvious systematic error, and then through adding an affine transformation in image space to compensate the systematic error. Experiment is made through two TH-1 satellite three-line images based on RPC model. The test result shows that few ground control points can improve the positioning precision of bias compensated RPC model greatly, and demonstrates the correctness and effectiveness of the RPC model.
