| 摘 要： | 文章针对一景大小的卫星三线阵CCD影像,采用二次多项式拟合外方位元素模型,与国外的定向片法模型进行平差算法对比.对一景大小的模拟数据进行了试验,结果表明基于二次多项式拟合外方位元素模型的平差方法有效的提高了影像的平面精度与高程精度,与定向片法模型相比,该算法简单,结果同样满足1∶5万摄影测量的要求.

| Abstract: | With adjustment of one scene satellite borne three-line array CCD imagery,The paper adopted the quadratic polynomials fitting exterior orientation model,comparing with orientation images model adopted abroad.The experiment results using one scene simulated data indicated that comparing with the orientation images model,bundle adjustment based on quadratic polynomials fitting exterior orientation model improved the image,s plane and elevation accuracy effectively,its algorithm is easier,and the results can also meet 1:5 million requirements of photogrammetry. |
