Abstract
Vision-based people localization systems in outdoor environments can be enhanced by means of radio frequency identification technologies. This combination has the potential to enable a wide range of new applications. When individuals wear a radio frequency tag, they may be both identified and localized. In this way, the technology may interact with individuals in a personalized way. In this paper, two radio frequency identification technologies, UHF Radio Frequency IDentification (RFID) and Bluetooth Low Energy (BLE), are combined with a stereo-based people detection system to recognize individuals in groups in complex outdoor scenarios in medium sized areas up to 20 m. The proposed approach is validated in crosswalks with pedestrians wearing portable RFID passive tags and active BLE beacons.
