Akashima Island, located in Goto City, Nagasaki Prefecture, is a small island with no running water and 16 inhabitants surviving on rainwater. This island has been the focus of our work since 2017. Notably, typhoons No. 9 and No. 10 passed consecutively near this island in early September 2020. In this study, we used aerial drone images captured before and after the typhoons passed to obtain differential information and verify whether these images could be used as part of a simple damage assessment method. Our results did not show significant differences in terms of visual damage. However, as the detection accuracy was not high, further image processing was performed to obtain results exhibiting potential for improving the accuracy. |
