Extreme weather events impact large areas in a very short time, resulting in significant damages on many residential houses. After disasters, a recovery process should be promptly implemented to recover damaged local communities, but there are too many structures to be repaired with a limited number of resources. In the post disaster phase, detailed information—such as a degree of damage and house types—is required to automate disaster recovery planning and execution. However, previous studies have not investigated a method that can generate information with adequate details required to automate disaster recovery planning. To fill the knowledge gap, this study aims at recognizing building objects, detecting building damages, and measuring the extent of damage to individual building properties from aerial image data collected by drones. Semantic segmentation is employed to recognized buildings and their damages. The degree of damage will be assessed by a set of rules reflecting current manual assessment guidelines. This work is expected to help reduce a large portion of the current manual process in assessing the degree of damage for damaged buildings, thereby facilitating rapid disaster recovery.
