摘　　要：提出了一种用于无人机航空影像镶嵌的自由网平差模型,该模型利用最小二乘原理,整体解算待镶嵌影像的仿射变换参数.实验结果表明,该模型较好地解决了影像镶嵌过程中误差伴随基线放大的问题,提高了影像镶嵌的精度.In this paper, a new model of free networks for remote sensing images was proposed in a bid to solve the parameters of affine transformation. The parameters of different images holistically were solved by least square method. The results showed that, in contrasted with traditional methods, the newly model could decrease the effect of accumulate error evidently and avoid strip deformation when the amount of images was large.
