应用低空无人机的长输管道测量研究

Research on the Measurement of Long Distance Pipeline Using Low Altitude UA V

传统的手动测量模式存在操作周期长、劳动投入大、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、航拍成像技术(可在困难地区进行探测)以及精确的后处理技术,大大降低了运营成本和生产周期。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。

The traditional manual measurement mode has many problems,such as long working cycle,large input of manpower,high cost,etc.,and even can not be measured in diff icult 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,eff icient,fast and diff icult 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 controllayout and image processing.
