摘　　要：针对目前道路损毁评估不够形象直观的问题,提出了一种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地容易判读。同时,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:这种方法更加地形象逼真,在此基础上,计算损毁地区的土方量,可以为工程设计部门和决策部门提供参考依据。Aiming at the problem that the evaluation of road damage is not intuitionistic enough, this paper puts forward a method for the evaluation of road damag visualized and e based on the high resolution satellite image, making the satellite image interpreted easily through pre-processing the satellite image such as image enhancement. At the same time, we set up a model of the road before and after damaged with the DEM data, and then 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, and provides the reference for the department of engineering design and decision.
