摘要
针对目前道路损毁评估不够形象直观的问题,提出了基于高分辨率遥感影像的道路损毁评估方法。通过对遥感影像进行影像增强等预处理使遥感影像更加容易判读,并利用损毁前后的DEM数据构建损毁前后道路模型,通过此模型来对道路损毁进行评估。实验表明:应用这种方法,道路模型形象逼真;在此基础上计算损毁地区的土方量,可为工程设计部门和决策部门提供影像数据参考。
Aiming at the problem that the evaluation of road damage is not visualized and intuitionistic enough,this paper puts forward a method for the evaluation of road damage based on high resolution satellite image making the satellite image interpreted easily through pre-processing the satellite image such as image enhancement.On the other hand we set up a model of the road before and after damaged with DEM data and evaluate the road damage with the model.The experiment indicates that the method is visualized and vivid,and calculates the volume of the damaged area＇s earthwork.Thus the result provides reference for the department of engineering design and decision.
