摘　　要：本文以某高校变形监测实验基地的一处边坡作为研究对象,探究了数字近景摄影测量技术在边坡变形监测中的应用。在布设控制点、像控点和监测点的基础上,使用TM30型全站仪展开外业测量。分别于2023年的3月份和8月份开展测量,获取像控点与监测点的三维坐标。基于单反数码相机开展近景摄影测量,将所得数据输入到Lensphoto软件中,经过数据处理后生成边坡三维模型。对比全站仪测量坐标与三维模型坐标,误差在±20 mm以内,说明数字近景摄影测量精度较高,满足边坡变形监测的要求。This article takes a slope in a deformation monitoring experimental base of a certain university as the research object,and explores the application of digital close range photogrammetry technology in slope deformation monitoring.On the basis of setting up control points,image control points,and monitoring points,field measurements are carried out using the TM30 total station.Surveys will be conducted in March and August 2023 to obtain the three-dimensional coordinates of image control points and monitoring points.Based on a DSLR digital camera,close range photogrammetry is carried out,and the obtained data is input into Lenphoto software.After data processing,a three-dimensional model of the slope is generated.Comparing the total station measurement coordinates with the three-dimensional model coordinates,the error is within±20mm,indicating that the digital close range photogrammetry has high accuracy and meets the requirements of slope deformation monitoring.
