Scheme Design and Experimental Analysis Based on Industrial Photogrammetry in Narrow Spaces

为解决当前在煤矿巷道、立井、隧道等地下狭长空间内通视条件差、无卫星信号、不易设站等因素导致测量困难的问题,本文提出了一种基于工业摄影测量系统的狭长空间点位测量方法。根据工业摄影测量网形设计的原则,进行狭长空间内点位测量初步方案设计,通过实验验证方案的可行性,并结合像片概略定向原理和误差传播定律,对比实验精度分析结果,对测量方案进行了多方面优化,确定最优方案。

In order to solve the problem of difficult measurement in coal mine roadway,shaft,tunnel and other underground narrow and narrow space,there is no satellite signal,it is difficult to set up station and other factors lead to measurement problems. A kind of narrow space measurement method based on industrial photogrammetry system The According to the principle of industrial photogrammetry,the feasibility of the scheme is verified by experimentally verifying the feasibility of the scheme. Combined with the principle of orientation and error propagation of the image,the experimental results are compared with the experimental results. Carried out a variety of optimization,to determine the optimal program.
