Abstract :
We introduce a calibration free hybrid RF and video surveillance system for reliable tracking, identification in Mass Casualty Incidents (MCI). The system fuses RF measurements along with information harvested from the video such as target temporal, kinematic, and appearance information. Our hybrid RF and video surveillance system can be deployed rapidly without manual calibration of either the camera or the RF devices, and can work in complex RF environments. This is made possible by the simultaneous identification and mapping algorithm that iteratively refines the mapping of the radio beacon signal strength signature to target positions in video frames. The system is the basis of identity aware video surveillance, i.e. enabling unique identification of targets in the video and applying identity specific analytics roles to individual targets.
