C302 地震後の空撮画像による建物被害地域の可視化

抄録

A visualization method for the areas with damaged buildings due to earthquakes using aerial images taken from light planes and helicopters was developed, and the application of the method to early damage assessment was discussed. Aerial television images and aerial photographs with a resolution of 10-20cm were examined. The method of detecting the difference between pre- and post-event images is often used in satellite remote sensing after highly accurate registration of images. However, it may be difficult to prepare pre-event images in an emergency response stage. The proposed methods based solely on post-event images can be employed efficiently in emergency management by using the mobility of platforms.
