受到纵向、横向以及内部空间应力作用的影响,边坡受力点会出现一定量的位移变形,为了防止边坡位移变形对边坡稳定性造成影响,提出基于无人机遥感影像的边坡位移变形监测技术。采用无人机遥感技术,利用遥感图像作为计算样本,通过建立遥感影像下边坡GM(1,1)模型、遥感影像的边坡小波变形识别计算、边坡变形数据拟合计算完成对边坡位移变形数据的识别,实现提升监测精准度的效果。通过实验数据证明,提出的监测技术具有边坡位移变形监测识别精度高、连续监测稳定性好、整体监测过程稳定的特点。

Under the influence of longitudinal,transverse and internal spatial stress,a certain amount of displacement and deformation appear at the stress point of the slope.In order to prevent the influence of slope displacement and deformation on slope stability,a slope displacement and deformation monitoring technology based on UAV remote sensing image is proposed.The UAV remote sensing technology is adopted,and the remote sensing image is used as the calculation sample to identify the slope displacement and deformation data by establishing the GM(1,1) model of the lower slope of the remote sensing image,the wavelet deformation identification calculation of the remote sensing image and the fitting calculation of the slope deformation data,so as to improve the monitoring accuracy.The experimental data show that the proposed monitoring technology has the characteristics of high accuracy of slope displacement and deformation monitoring and identification,good stability of continuous monitoring and stable overall monitoring process.
