FLASH:无人机滑坡灾情轻巧感知系统
FLASH:Flexible and lightweight awareness of slope hazard
摘要
Abstract
To address the urgent needs of emergency response for major landslide disasters under extreme condi-tions such as disconnected roads,power outages,and network failures,this study designs and develops FLASH,a lightweight UAV-based landslide perception system which integrates hardware and algorithms.The hardware system includes a lightweight perception module and real-time interpretation unit,designed as decoupled standalone nodes.Utilizing ROS-based messaging and serial communication for low-latency data transfer,the system operates at a peak power of 25 W and weighs 500 g.Algorithmically,a lightweight design model incorporating spatial-informational con-straints is proposed,which maintains inference accuracy while drastically reducing latency for semantic segmentation of ultra-high-resolution images(e.g.,78.88 ms per 7 952×5 304 image).The model further enables intelligent multi-image landslide retrieval and volume estimation via deep semantic representation,achieving 81%reliability in volume calculations(validated in the Songpan landslide case)without relying on 3D reconstruction.Ultimately,this system re-alizes the fully automated extraction of critical disaster information from UAV imagery acquisition to landslide volume estimation,significantly enhancing the efficiency of landslide disaster interpretation.关键词
