This paper introduces a method for quantifying the three-dimensional deformation of ground targets and outlines the associated process. Initially, ground-based synthetic aperture radar was employed to monitor the radial deformation of targets, and optical equipment monitored pixel-level deformation in the vertical plane of the line of sight. Subsequently, a regression model was established to transform pixel-level deformation into two-dimensional deformation based on a fundamental length unit, and the radar deformation monitoring data were merged with the optical deformation monitoring data. Finally, the fused data underwent deformation, resulting in a comprehensive three-dimensional deformation profile of the target. Through physical data acquisition experiments, the comprehensive three-dimensional deformation of targets was obtained and compared with the actual deformations. The experimental results show that the method has a relative error of less than 10%, and monitoring accuracy is achieved at the millimeter level.
本文介绍了一种用于量化地面目标三维变形的方法，并概述了相关过程。首先，利用地基合成孔径雷达监测目标的径向变形，光学设备监测视线垂直平面内的像素级变形。随后，建立回归模型，基于基本长度单位将像素级变形转换为二维变形，并将雷达变形监测数据与光学变形监测数据合并。最后，对融合后的数据进行变形处理，得到目标的综合三维变形轮廓。通过物理数据采集实验，获得了目标的综合三维变形，并与实际变形进行了比较。实验结果表明，该方法的相对误差小于10%，监测精度达到毫米级。
