FloodVision framework improves flood depth estimation using VLM and knowledge base

By PulseAugur Editorial · [1 sources] ·

Researchers have developed FloodVision, a new framework designed to improve the accuracy of estimating urban flood depths from single RGB images. This system integrates a general-purpose vision-language model (VLM) with FloodKG, a knowledge base containing canonical object dimensions and landmarks. By encouraging component-level reasoning rather than treating objects as wholes, FloodVision injects explicit geometric grounding without requiring task-specific training. When tested on crowdsourced images from MyCoast New York, FloodVision significantly reduced mean absolute error from 15.62 cm to 8.75 cm and median error from 14.35 cm to 7.75 cm, outperforming a VLM-only baseline in over two-thirds of cases. AI

IMPACT Enhances the accuracy of AI-driven flood depth estimation, potentially improving emergency response and urban planning.
