The purpose of our study is to consider the automatic detectionmethod of detailed information on the ground using low resolution aerial images onwide areas and to apply the method for obtaining the road information on wide areas required for the rescue activities in the large-scale disaster. For this purpose, we considered the automatic detection method of road blockages by cooperative analysis of varying information around the road areas from low resolution aerial images, and we built the trial system. Furthermore, we experimented and evaluated the method using thereal images obtained in the large-scale disaster. In the results, we showed the realization of automatic detection of road blockages caused by the rubbles and floods.

我们研究的目的是考虑利用低分辨率航拍图像自动检测大范围地面详细信息的方法，并应用该方法获取大规模灾害救援活动所需的大范围道路信息。为此，我们考虑了通过对低分辨率航空图像中道路区域周围的变化信息进行协作分析来自动检测道路堵塞的方法，并构建了试验系统。此外，我们利用大规模灾难中获得的真实图像对该方法进行了实验和评估。在结果中，我们展示了自动检测瓦砾和洪水造成的道路堵塞的实现。
