Abstract :A new method of landslide monitoring is presented by applying the close-range photogrammetry technology into
landslide monitoring without surveying control points again ,which is convenient ,fast and non-contact.This method uses the ro-
tated photogrammetry or parallel photography way to take a group of photographs for monitoring area.Then the DEM model
of target monitoring area is obtained based on photography measurement principle.The absolute displacement and the local
variation of landslide during the monitoring period can be calculated by automatic matching of control points and overlaying
analysis of two stage DEM models.Experimental results using synthetic data indicate that the presented method can be effec-
tive for a rapid and exact monitoring.
Key words :close-range photogrammetry ;landslide monitoring ;automatic matching of control points ;overlaying analysis of
DEM models
摘 要:將近景攝影測量技術應用于山體滑坡監(jiān)測中,提出一種無需二次控制的、非接觸的、快速的滑坡監(jiān)測方法。方法采用旋
轉攝影或正射平行攝影的方式,對監(jiān)測區(qū)域進行攝影,根據(jù)攝影測量原理獲取目標監(jiān)測區(qū)域的DEM 模型。通過自動匹配控制點
以及對兩期DEM 模型進行疊加分析,計算出山體在該時間段內(nèi)
