【摘要】：介绍了资源三号卫星三线阵立体像对全国无控制整体区域网平差的关键技术及应用,主要包括高精度稳态重成像处理技术、基于虚拟控制点的平差模型构建技术、粗差(包括几何精度异常影像、误匹配点)的探测与剔除技术以及超大规模平差方程的高效解算方法。在此基础上,对覆盖全国的8 802个资源三号三线阵立体像对(共26 406景影像)在无控制条件下整体一张网的平差结果及精度验证情况进行分析。实验结果表明,该方法不但可以保证区域网整体的绝对无偏估计,还可以有效控制区域网内部几何误差的传递与累积,从而避免网的变形,以保证网内几何精度的一致性与均匀性。此外,还列出了本技术在全球测图工程中德国试验区的示范应用情况。
[Abstract]:This paper introduces the key technology and application of the three-line array stereo image of Resource-3 satellite to the adjustment of the whole area network without control in the whole country. It mainly includes the technology of high-precision steady-state reimaging processing and the construction technology of adjustment model based on virtual control point. The detection and elimination technology of gross error (including geometric precision abnormal image, mismatch point) and the efficient solution method of large scale adjustment equation. On the basis of this, the adjustment results and accuracy verification of 8 802 three-line array stereo pairs (a total of 26406 scene images) covering the whole country under the condition of no control are analyzed. The experimental results show that this method can not only guarantee the absolute unbiased estimation of the whole area network, but also effectively control the transfer and accumulation of geometric errors in the network, thus avoiding the distortion of the network. In order to ensure the consistency and uniformity of geometric accuracy in the network. In addition, the application of this technology in the German experimental area in global mapping engineering is also listed.
