全景影像技术在地质灾害防治信息化中的应用

On the application of panoramic image technology in informationization of geological hazard prevention and control

传统的地质灾害野外调查照片难以全面拍摄到灾害体范围和受威胁对象的整体情况,而全景影像技术很好地解决了这个难点,其在地质灾害防治信息化中的用途也越来越重要。目前野外调查中主要使用的是无人机航拍全景技术,但是有一定的条件限制。全景地拍由于专业性强、知识复杂、操作难度大,掌握和使用此项方法的人较少。传统照片拍摄技术与全景影像拍摄技术两者可以相互补充,也可以单独使用。因此,有必要对现在主要的全景影像拍摄方法与技术要点进行分析,最终目的是准确得到所需要的影像资料,并将其应用于地质灾害防治信息化工作中。

Traditional field survey photos are difficult to fully reflect the overall situation of a geological hazard and the threatened object,but the panoramic image technology can solve this issue very well,and becomes more and more important when being applied in the process of informationization of prevention and control of geological hazards.At present,the UAV aerial panoramic photography is mostly used in field surveys though it has some restrictions.Panoramic shooting is hard to operate and thus less used because it is a very professional technology that involves in complex knowledge.The traditional and panoramic photography can be either used together or alone.Therefore,the major shooting methods and technical points of panoramic photography need to be analyzed for the purpose of obtaining the required images,which can then be applied to geological hazard prevention and control informationization.
