基于广义点摄影测量的后方交会与前方交会方法研究

Spatial resection and forward intersection with generalized point photogrammetry

广义点摄影测量将传统的点摄影测量和当代发展的线摄影测量以及无穷远点理论综合升华,将摄影测量中处理的物理意义上的点扩展到数学意义上的广义点。本文主要研究广义点摄影测量理论下的后方交会和前方交会解算方法。分析评价了不同控制线分布情况对后方交会精度的影响;依据前方交会原理,对闭合直线段和圆进行了三维重建,取得了良好的效果。

This paper mainly focused on the approach of forward intersection and resection with generalized point photogrammetry. The influence of different distribution of control line on the final accuracy of spatial resection was discussed. Finally, based on the forward intersection principle, the rectangle shaped buildings and circles were reconstructed.
