中文摘要：
从高分辨率卫星影像区域网平差的模型出发,针对高分辨率卫星影像CCD线阵推扫成像的特点,研究其基于有理多项式模型RPC（Rational Polynomial Coefficient,or Rapid Position Capability）和少量控制点的区域网平差算法,并对重庆某地区的Word View-2卫星影像进行区域网平差处理试验,统计不同控制点布设方案下平差处理的精度,试验结果表明在稀少控制条件下本文方法可以实现卫星影像的正射纠正,能满足地理国情普查、地形图测绘等方面的需求。
英文摘要：
In this paper, We present a research on block-adjustment of high resolution satellite images based on Ra- tional Function Model（RPC）with sparse GCPs,considering with the property of CCD line push-broom. We also make block-adjustment experimentation using WorldView-2 images of an area in Chongqing, and analysis the precision of block-adjustment with different control point setting projects. The results show the proposed method is effective on Ortho -calibration of satellite images with sparse GCPs, and can meet the needs of national geographical condition surveying, topographic map producing, and other applications.
