Computer Engineering and Applications ，2011 ，47 （3 ）：6-8. 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(cè)量技術(shù)應(yīng)用于山體滑坡監(jiān)測(cè)中，提出一種無需二次控制的、非接觸的、快速的滑坡監(jiān)測(cè)方法。方法采用旋 轉(zhuǎn)攝影或正射平行攝影的方式，對(duì)監(jiān)測(cè)區(qū)域進(jìn)行攝影，根據(jù)攝影測(cè)量原理獲取目標(biāo)監(jiān)測(cè)區(qū)域的DEM 模型。通過自動(dòng)匹配控制點(diǎn) 以及對(duì)兩期DEM 模型進(jìn)行疊加分析，計(jì)算出山體在該時(shí)間段內(nèi)
