摘要
我国城市发展迅速,需要用DInSAR+倾斜摄影测量技术进行城市大地形变测量。应用DInSAR及改进的沉降监测技术取得H市两个时间段地面形变监测成果后,经精密水准测量检验,证实结果可靠。倾斜摄影测量技术不断进步,经大量实践,已成为城市形变监测的又一选择。应用DInSAR+倾斜摄影进行城市形变监测,打破了传统形变测量的手段和理念,实现与基础成果的全景比对或相同点位真三维对比,亦可对城市的点、面、体,局部或全方位进行形变监测,监测成果可互为验证。文中并对试点区使用设备、技术标准、作业方法等进行了设计研究。
The rapid development of cities in China encourages the use of DInSAR+oblique photography technology to measure urban geodetic deformation.In this paper,DInSAR and improved subsidence monitoring technology are applied to monitoring the ground deformation of two time periods in H City,and the results are proved to be reliable by precise levelling measurement.As the continuous improvement and practice of oblique photography technology,it has become another reliable technology for urban deformation monitoring.Different from the traditional methods and concepts of deformation measurement,the application of DInSAR and oblique photography technology for urban deformation monitoring achieves a panoramic comparison with the fundamental results and a true three-dimensional comparison of the same point.It can also monitor the deformation of cities from geological dot,plane,body,local area or omni-direction,and the monitoring results can be verified mutually.The use of equipment,technical standards,and operating methods in the pilot area also discussed in the paper.
