自然灾害常造成严重建筑损毁,亟需快速、可靠且低成本的灾后损毁评估以支持应急响应。然而传统方法依赖静态、人力密集的数据采集策略,成本高且难以适应灾后动态变化。本文提出一种成本感知的贝叶斯优化框架,结合水平集估计,持续引导自主数据采集设备(如无人机)前往信息量最大的区域。通过动态更新不同地理区域的损毁估计,该方法系统性降低不确定性,同时最小化操作成本。首先在可控合成玩具实验中验证,代理能高效追踪损毁边界,重建原始损毁图,并快速减少预测不确定性。进一步在基于区域韧性评估(R2D)软件生成的高保真灾害数据上测试,算法输出准确及时的损毁估计,有效支持高效决策。

原文摘要 · Abstract (English)

Natural disasters frequently inflict severe damage to the built environment, which demands a rapid, reliable, and cost-effective damage assessment for emergency response. However, traditional methods for post-disaster damage assessment often rely on static, labor-intensive data collection strategies that can be prohibitively expensive and struggle to adapt to dynamic post-disaster conditions. In this study, we propose a cost-aware Bayesian optimization framework combined with level-set estimation that continuously guides autonomous data collectors, e.g., an unmanned aerial vehicle (UAV), toward the most informative regions. By dynamically updating damage estimates across different geographic zones, our approach systematically reduces uncertainty while minimizing operational costs. The proposed framework is first validated using a controlled synthetic toy study, demonstrating the agent's ability to efficiently trace damage boundaries, recover the underlying damage map, and rapidly reduce predictive uncertainty. Furthermore, the approach is evaluated using high-fidelity disaster data generated by the Regional Resilience Determination (R2D) software. The results of the algorithm provide accurate and timely damage estimates that support informative and fast emergency response.
