Interactive system for real-time detection and GIS registration of damaged houses using mobile devices to streamline damage assessment

Streamlining damage surveys during disasters is essential for the prompt issuance of disaster certificates, thereby facilitating accurate assessment of damage conditions and the early implementation of support measures. However, in the current survey workflow, surveyors must manually record the damage level and location of each house, and then match this information with GIS entries, which requires significant time and effort. To address this issue, this paper proposes an interactive mobile system that estimates the absolute positions and damage levels of houses by combining camera-based house detection, SLAM-based device pose estimation, and device sensor data, and then automatically registers the results in the GIS. In experiments, we evaluated the effectiveness of the proposed system using both miniature house models and real buildings.
