<p>The present invention concerns a method and system for the short-range localization, i.e. within tens of meters, of collaborative (active) objects, i.e. with communication means associated, and non-collaborative (passive) objects, i.e. without communication means associated. The method uses both radio ranging and ultrasonic ranging in order to determine presence and distances within and with respect of a network of anchor nodes. Radio ranging is used for active objects and ultrasonic ranging is used both for passive and active localization. The system can be used for localization in logistic, short-range navigation, security and surveillance, entertainment, tracking of goods and personnel, sensible area monitoring etc.</p> |
