摘要
无人机倾斜摄影技术构建全景真三维影像极大提高了单体灾害解译的精度及准确度,也可以用于研究单体灾害动态演变规律的数据积累,降低了多期数据获取的难度和成本,为应急救援决策提供更加科学的技术支撑。本文以利用旋翼无人机倾斜摄影技术在茂县6·24地质灾害应急调查的成功实践为基础,系统地建立了一套基于旋翼无人机倾斜摄影技术的高位滑坡单体地质灾害应急调查方法,并在会东老君洞高位滑坡地质灾害应急中证明该方法的适用性,大大提高单体灾害应急处置效率。
Thanks to building three-dimensional real space scene, tilt photography technology improves greatly the precision and accuracy of individual hazards interpretation, thus can be used for studying the accumulation of data on the dynamic evolution of individual hazards, in order to reduce the difficulty and cost of multi-period data acquisition, and to provide more scientific technical support for emergency rescue decision-making. Based on the successful practice of the unmanned aerial vehicle remote sensing(UAVRS) technology in the emergency investigation of "6·24"geohazards in Maoxian County, this paper systematically establishes a set of emergency investigation methods for ridge-top landslide by means of tilt photography of UAVRS. These methods prove the emergency investigation of ridge-top landslide in Laojundong, Huidong, greatly improving the efficiency of emergency disposal of individual hazards.
