无人机倾斜摄影技术在地震烈度评估中的应用——以九寨沟7.0级地震为例

摘要

以九寨沟7.0级地震为例,通过阐述无人机倾斜摄影技术的相关原理,说明该技术在地震烈度评估中的应用价值.结果表明,使用无人机倾斜摄影技术不仅能够直观地、全方位地展示震害信息,同时,还能对裂缝、滑坡等几何信息进行量测,为烈度评估等提供更加精确的信息.%This paper illustrates the application of UAV oblique photography in seismic intensity assessment by describing the relevant principles in the case of the Jiuzhaigou MS7.0 earthquake.The results proved UAV oblique photography can not only show the earthquake damage information intuitively and comprehensively,but also measure cracks,landslides and other geometricinformation,and all of these provide more accurate information for the intensity evaluation.
