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：将近景摄影测量技术应用于山体滑坡监测中，提出一种无需二次控制的、非接触的、快速的滑坡监测方法。方法采用旋 转摄影或正射平行摄影的方式，对监测区域进行摄影，根据摄影测量原理获取目标监测区域的DEM 模型。通过自动匹配控制点 以及对两期DEM 模型进行叠加分析，计算出山体在该时间段内
