摘要
Optimizing the RPC（Rational Polynomial Coefficient） model can improve the positioning accuracy of the RPC correction model. Taking an IRS-P5 image for example, in the cases of using 0~9 control points or using compensation model, the authors analyze the accuracy change of the image ortho correction. The results show that the accuracy can be improved from 55.80 m to 5.80 m when increase the control points from 0 to 1; while the accuracy is close to 5.0 m when the number of control points is more than 5.
