机载LiDAR技术在地质灾害监测中的应用研究

Application of Airborne LiDAR Technology in Geological Disaster Monitoring

利用成熟的技术路线和地质灾害监测点激光点云的特征,以及地裂缝的地形深度急剧变化规律,采取一种改进Morove算子的兴趣点提取方法,根据高程变化特征提取地裂缝;根据滑坡体的地形非连续性,在三角形生长算法基础上,采用异变点不参与构网的方法,使滑坡体与原山体地形分离,监测出山体滑坡地质灾害点,为地质灾害的监测提供新的思路和方法。

This article based on the mature technical route and the characteristics of the laser point cloud of the geological disaster mo- nitoring point, and take a method to improve the Morove operator＇s point of interest extraction according to the terrain depth of the ground fissures, and extract the ground fissures according to the elevation characteristics. According to the landslide Terrain no uni- formity, based on the triangular growth algorithm, the use of mutation point does not participate in the construction of the network, the landslide body and the original mountain terrain separation, monitoring the landslide geological hazard point for the monitoring of geo- logical disasters to provide new ideas and method.
