First Claim
Patent Images
1. A device for identification of at least one object in an image registered with an image registration device, where each of the at least one objects is provided with a wireless tag having stored thereon identification information related to the at least one object, the device for identification comprising:
- at least one transmitter operable for transmitting at least one interrogation signal;
at least two sensors operable for detecting wireless response signals from wireless tags responding to the at least one interrogation signal, wherein each wireless response signal from the wireless tag comprises identification information related to the at least one object, wherein a direction to each of the wireless tags is estimated based on a phase difference of the wireless response signals detected by the at least two sensors.
