Application of Digital Close Range Photogrammetry Technology in Slope Deformation Monitoring
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.
