摘要
输电铁塔的倾斜监测与评价是保证输电铁塔正常运行的关键。然而,由于输电铁塔的叠掩现象,传统的遥感成像技术难以适用。文中采用一种改进的DInSAR方法对输电铁塔倾斜位移进行估计,使用Radarsat-2数据、TerraSAR-X数据和现场监测数据进行验证。结果表明:该方法是一种提取输电铁塔的顶端倾斜位移的有效方法。
The monitor and evaluation of the state of the electric power transmission tower is crucial to ensure the normal operation of the transmission line.Due to overlying effects of transmission tower,its inclination displacement is difficult to extract by traditional remote sensing imaging technology.In this paper,an improved DInSAR model is used to estimate the inclination displacement if transmission towers,the model is validated by Radarsat-2 data,TerraSAR-X data and field monitoring data.The results shows that it is an effective method to extract the inclination displacement of the transmission tower.
