A cooperative perception system for multiple UAVs: Application to automatic detection of forest fires

This paper presents a cooperative perception system for multiple heterogeneous UAVs. It considers different kind of sensors: infrared and visual cameras and fire detectors. The system is based on a set of multipurpose low-level image-processing functions including segmentation, stabilization of sequences of images and geo-referencing, and it also involves data fusion algorithms for cooperative perception. It has been tested in field experiments that pursued autonomous multi-UAV cooperative detection, monitoring and measurement of forest fires. This paper presents the overall architecture of the perception system, describes some of the implemented cooperative perception techniques and shows experimental results on automatic forest fire detection and localization with cooperating UAVs.
