基于DLG与建筑物多层控制结构的近景影像解算

The close range image calculation based on DLG and building multi-layer control structure

利用近景影像中建筑物上多个平面的特征点构成的多层控制结构条件,对传统的共线方程进行拓展,通过逐渐趋近的整体严密迭代平差方法,解算出影像参数、影像定位信息及建筑物各层状结构高度,试验结果表明多层控制结构解算方法具备严密性、精确性、可靠性。

This paper used the multi-layer control structure situation constituted by building multiple planar features in close range image,expanded the traditional collinearity equation,through the gradually approaching whole tight iterative adjustment method,calculated the images parameters,image positioning information and building each layer shape structure height,the experimental results showed that the mul-tilayer control structure calculation method with rigor,accuracy and reliability.
