ROTATION BASED ALIGNMENT OF A GROUP OF WIRELESS TAGS |
摘要 |
A method for determining a location of a wireless tag, the method may include generating or receiving, by a tagged mobile device, an estimated location of another tag that communicates with the tagged mobile device; receiving or generating, by the tagged mobile device, multiple distance measurements that are obtained during different points of time; wherein the multiple distance measurements are obtained during a rotational movement of the tagged mobile device and represent distances between the tagged mobile device and the other tag; finding a certain angle of rotation of the mobile device that corresponds to a minimal distance measurement of the multiple distance measurements; and amending the estimated location of the other tag based upon the certain angle of rotation. |

1. A method for determining a location of a wireless tag, the method comprising:
generating or receiving, by a tagged mobile device, an estimated location of another tag that communicates with the tagged mobile device; receiving or generating, by the tagged mobile device, multiple distance measurements that are obtained during different points of time; wherein the multiple distance measurements are obtained during a rotational movement of the tagged mobile device and represent distances between the tagged mobile device and the other tag; finding a certain angle of rotation of the mobile device that corresponds to a minimal distance measurement of the multiple distance measurements; and amending the estimated location of the other tag based upon the certain angle of rotation. |
