摘要
相对于传统的地质灾害测量技术,包括全站仪、近景摄影测量以及航空摄影测量等技术,三维激光扫描测绘技术具有精度高、速度快、分辨率高、非接触式以及优良的兼容性等优势。本文主要以湖北省黄冈市黄梅县地质灾害详细调查中遇到的困难为例,如地形高差相对较大、危岩体较多等困难,利用三维激光的技术优势,保证内业成图精度与人员安全,减少外业时间及费用成本,为地质调查提供可靠数据。
Compared with the traditional geological hazard surveying technology,including total station,close range photogrammetry and aerial photogrammetry,three-dimensional(3D)laser scanning surveying and mapping technology has the advantages of high precision,fast speed,high resolution,non-contact and excellent compatibility.In this paper,mainly taking the difficulties encountered in the detailed investigation of geological disasters in Huangmei County,Huanggang City,Hubei Province as an example,there are difficulties such as relatively large terrain elevation differences and numerous dangerous rock bodies,3D laser was utilized with the technological advantages to ensure the accuracy of internal mapping and personnel safety,reduce external time and cost,and provide reliable data for geological surveys.
