| 摘 要： | 天绘一号卫星以RPC参数作为主要的影像辅助数据提供给用户,对传感器的技术参数进行隐藏.文中简要介绍RPC模型的立体定位方法,并针对定位结果中存在的明显的系统误差,采用像方补偿方案进行补偿,最后利用两景天绘一号卫星三线阵影像RPC模型对测区进行实验验证和分析.结果表明,采用少量地面控制点进行系统误差补偿后,定位精度提升效果明显,验证了模型的正确性和有效性. |
| 关 键 词： | 天绘一号卫星 立体定位 RPC模型 系统误差 |

| Abstract: | TH-1 satellite＇s administer sends RPC to the users as the main auxiliary data in order to hide the sensor＇s technique parameters. The methods of stereo positioning based on the RPC model, and the key problem of obvious systematic error is analyzed, and then through adding an affine transformation in image space the systematic error is compensated. 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 RPC model. |
| Keywords: | TH-1 Satellite stereo positioning RPC model systematic error |
