3D characterization of smoke plume dispersion using multi-view drone swarm.
🤖 AI Summary
Accurately modeling the three-dimensional (3D) dynamics of wildfire smoke plumes remains challenging, limiting the reliability of fire spread prediction and prevention decision-making. To address this, this paper proposes a collaborative multi-UAV observation framework for real-time 3D dynamic plume modeling. We introduce the first textureless smoke plume reconstruction method grounded in asynchronous multi-view geometric constraints, integrating coordinated multi-UAV trajectory planning, multi-view stereo matching, sparse-dense hybrid optical flow estimation, and adaptive voxel-based plume reconstruction. This approach overcomes limitations of single-platform observation and enables robust modeling of highly deformable, time-varying plumes. Validated in real wildfire scenarios, the system achieves centimeter-level depth accuracy and sustains 10 Hz point-cloud update rates. Plume motion trajectory prediction error is reduced by 37%, significantly enhancing the fidelity of fire propagation forecasting and operational responsiveness in emergency management.
