Application of Close-range Photogrammetry in Slope Deformation Monitoring
In this paper,Canon EOS600D digital SLR camera is used to take the images of the slope of a hydropower station in the field,and the images are transformed into the coordinate system of the survey area by setting the reference point sign,and then the Lensphoto software is used to process the shooting images.After processing such as aerotriangulation matching,aerotriangulation inter-section,and block bundle adjustment,a three-dimensional model of the high slope of the hydropower station dam is generated,and the three-dimensional models of different monitoring periods are compared to obtain the slope deformation data.By the layouting of 14 checkpoints,it uses a high-accuracy total station to obtain the coordinate data of the checkpoints,and compares and analyzes it with the close-range photogrammetry monitoring results.It verifies the reliability of the multi-baseline close-range photogrammetry slope monitoring results,which can meet the safety monitoring requirements of high slopes and provide high slope operation safety monitoring with a low-cost and high-accuracy solution.
