Optical Deformation Monitoring Based on Ground-Based Synthetic Aperture Radar Ranging and Regression Prediction

Optical deformation monitoring is a crucial component of three-dimensional deformation monitoring. It commonly employs optical sensors., such as cameras., to detect the pixel deformation of the target. However., it is challenging for a single camera to accurately convert pixel deformation into real-world deformation. In this paper., the detection range of the target is determined using ground-based synthetic aperture radar. Subsequently., the pixel deformation quantity captured by the optical camera is converted into actual two-dimensional deformation using regression prediction. Through the physical experiment., the root mean square error of this method is less than 6%., making it an effective tool for monitoring two-dimensional deformations of targets.
