尝试将光束法区域网平差模型从单一数据扩展到多源数据,以线阵CCD和SAR两种遥感影像构像模型为例,建立一种"复合式"光束法区域网平差模型,并定义相应的权矩阵,通过整体答解获得像片的外方位元素和加密点的大地坐标。利用一组由三幅不同卫星影像构成的区域网进行平差试验,试验结果证明该平差模型的正确性,并分析影响平差精度的因素。

The source data of bundle block adjustment has been extended from single-source to multi-source in this paper. A composite bundle block adjustment model and corresponding weight matrix have been constructed based on imaging models of linear CCD and SAR remote sensing images. It has been used to achieve exterior orientation elements of each image and ground coordinates of pass points by integral solution. The spatiotriangulation experiment was applied to 3 images in one block (panchromatic SPOT-5 HRV, panchr...
