| 摘 要： | 针对无控制点条件下测绘卫星影像区域网平差迭代难以收敛和影像重叠区域存在接边误差的问题,提出了一种基于基准影像的区域网平差方法。利用资源三号卫星影像进行无控制点条件下的区域网平差时,相对于LEVENBERG MARQUARDT算法,基于基准影像的区域网平差方法能得到较为稳定的平差解和较好的平差精度。为进一步验证方法的适用性,利用异轨长条带天绘一号卫星影像数据进行无控制点条件下的区域网平差。实验结果表明,基于基准影像的区域网平差方法显著优化了卫星影像的内部符合精度,为下一级卫星测绘产品的高精度处理奠定了基础。

| Abstract: | To solve the problem of iteration diverge in surveying satellite imagery block adjustment without ground control point and correct the edge match errs in the areas of image overlaps,a block adjustment method which is based on based images is established.Compared with the LEVENBERG MARQUARDT algorithm,this method can get a stable adjustment value and a good inner block adjustment precision using ZY-03 images without ground control point.To test the applicability of this method,multiple trips of TH-01 images are used for block adjustment without ground control point.The experiment results show that this method can improve the inner block adjustment precision and provide a basis for the high precision processing of the next level of surveying products. |
