Tracking objects in a two dimensional space

A system for tracking tagged objects in a two-dimensional space, comprising:

• a memory device for storing program code;
• and
• at least one processor device operatively coupled to the memory device and configured to execute program code stored on the memory device to:
• sequentially activate:
• first tracking devices of a plurality of tracking devices that read tagged objects in the two-dimensional space that are within reading ranges of the first tracking devices;
• and
• second tracking devices of the plurality of tracking devices that read tagged objects in the two-dimensional space that are within reading ranges of the second tracking devices;
• compare data collected from each of the plurality of tracking devices to identify that at least given one of the tagged objects has been read by at least two of the plurality of tracking devices;
• and
• determine a location of the given tagged object based on the locations of the at least two tracking devices that read the tagged objects.

A computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions being executable by a computer to cause the computer to perform a method for tracking tagged objects in a two-dimensional space, the method comprising:

• sequentially activating:
• first tracking devices of a plurality of tracking devices that read tagged objects in the two-dimensional space that are within reading ranges of the first tracking devices;
• and
• second tracking devices of the plurality of tracking devices that read tagged objects in the two-dimensional space that are within reading ranges of the second tracking devices;
• comparing data collected from each of the plurality of tracking devices to identify that at least given one of the tagged objects has been read by at least two of the plurality of tracking devices;
• and
• determining a location of the given tagged object based on the locations of the at least two tracking devices that read the tagged objects.
