摘要
传统的江河堤岸崩岸监测方法在检测过程中需耗费大量的人力、物力且存在人员安全风险。为优化这一过程,将无人机倾斜摄影与实景三维重建技术应用于堤岸空间数据获取与堤岸模型建立对比分析当中。借助无人机低空航拍技术获取堤岸测区的遥感数据影像信息,使用实景三维重建技术建立堤岸实景三维模型,将不同时序下的堤岸模型进行对比分析得到变化区域,并在长江荆江门河段治理中进行了实际测试。研究结果表明,基于无人机倾斜摄影的崩岸监测技术能够经济有效地记录和监测崩岸的治理过程中发生变化的区域,适用于危险性高、测区面积过大的堤岸智能化检测,具有一定的工程实用价值。
In recent years, the dangerous situation of landslides along the Yangtze River has occurred frequently, which has seriously affected the safety of people’s lives and property along the yangtze river, and the traditional manual monitoring method process consumes a lot of manpower, material resources and there are personnel safety risks. In order to optimize this process, the UAV oblique photography and real-life three-dimensional reconstruction technology are applied to the comparative analysis of the spatial data acquisition of the embankment and the establishment of the embankment model. With the help of UAV low-altitude aerial photography technology, remote sensing data image information of the embankment measurement area was obtained, the real scene 3 D reconstruction technology was used to establish a real-life 3 D model of the embankment, and the embankment model under different time sequences was compared and analyzed to obtain the change area, and the actual test was carried out in the governance of the Jingjiangmen section of the Yangtze River. Through the comparison of pre-and post-production data, the proposed method proved that the proposed method can cost-effectively record and monitor the areas that have changed during the governance process of the landslide.
