Abstract
Embodiments are directed to a method of identifying an identification (ID) tag. The method includes using a movable reader to determine a presence of an ID tag, an absence of the ID tag and that the ID tag has moved. The method further includes using the movable reader to determine a localization probability score of the ID tag, and, based on the localization probability score, adjust the movable reader's determination of the presence of the ID tag.
Claims19
A method of performing an object identification (ID),
- the method comprising:
- using a movable reader to determine:
- a presence of an ID tag;
- an absence of said ID tag;
- and
- that said ID tag has moved from one location to another location;
- and
- the method further comprising:
- using the movable reader to:
- determine a localization probability score of said ID tag;
- and
- based on said localization probability score, adjusting a determination by said movable reader of said presence of said ID tag.
An object identification (ID) system comprising;
- a movable reader configured to define, adjust and track a first trigger zone of a first ID tag by determining a presence of said first ID tag within said first trigger zone;
- said movable reader further configured to define, adjust and track a first miss zone of said first ID tag by determining an absence of said first ID tag from said first miss zone;
- and
- said movable reader further configured to determine a first localization probability score of said first ID tag;
- wherein said first localization probability score comprises a likelihood that said movable reader will, while at a first current location, determine said presence of said first ID tag.
An object identification (ID) system, comprising:
- a first movable reader configured to define, adjust and track a first trigger zone of a first ID tag by determining a presence of said first ID tag within said first trigger zone;
- a second movable reader configured to define, adjust and track said first trigger zone of said first ID tag by determining said presence of said first ID tag within said first trigger zone;
- and
- a communications network connecting said first movable reader and said second movable reader;
- wherein said first movable reader is further configured to access and utilize, through said communications network, stored data of said second movable reader to define, adjust and track said first trigger zone of said first ID tag.
