公路航测的精度分析和航摄比例尺的选择

The Precision Analysis of Highway Aerial Survey and Selection of Aerial Photographical Scale

本文引入了测点、地物真实位置的概念,从公路勘测规范和摄影测量原理出发,分析了常规测量方法和航测中的点位精度,由此提出了满足公路测设要求的公路航测的点位精度,并提出了不同成图仪器、不同航摄仪条件下公路一次航摄多测设阶段应用的航摄比例尺。

Based on the highway survey specification and the photogrammetric survey principle,the concept of true position of the station point or the surface body is introduced in this paper,from which the precision requirement of the position of a station point comparable to the conventional survey is here set up in accordance with the highway survey requirement.Furthermore,the photographical scale for one stage survey in replacing the multi-staged highway survey and design by means of different photogrammetric equipment is recommended in the paper.
