无人机航摄系统在管道测量中的应用研究

Application of UAV Aerial Photography System in Pipeline Survey

传统人工测量模式存在作业周期长、人力投入大、成本高等问题,甚至会出现困难地区无法施测,无法满足高难度、快节奏测量生产的需要。低空无人机航摄技术,凭借其自身机动灵活、高效快速、困难地区探测的航片获取技术,以及精准的后处理技术,大大降低了作业成本和生产周期,在“短、平、快”的长输管道线路地形图测绘方面具有明显优势。本文主要探讨无人机航测系统在1∶2000线路测量中的应用思路,包括数据获取、像控布设及影像处理等。

There are many problems in the traditional manual measurement mode,such as long working cycle,large input of manpower,high cost,etc.,and even can not be measured in difficult areas,which can not meet the needs of high difficulty and fast-paced measurement production.Low altitude UAV aerial photography technology,with its own flexible,efficient,fast and difficult area detection aerial capture technology,as well as accurate post-processing technology,greatly reduces the operating cost and production cycle,and has obvious advantages in the"short,flat and fast"topographic mapping of long-distance pipeline route.This paper mainly discusses the application of UAV aerial survey system in 1:2000 line survey,including data acquisition,image control layout and image processing.
