Deep learning-based store realograms

A method for tracking inventory items in an area of real space, the method including:

• using a plurality of sensors to produce respective sequences of images of corresponding fields of view in the real space, the field of view of each sensor overlapping with the field of view of at least one other sensor in the plurality of sensors;
• identifying inventory events using the sequences of images produced by at least two sensors in the plurality of sensors;
• tracking locations of inventory items in the area of real space in response to the identification of inventory events,
• matching locations of inventory items with coordinates of cells in a plurality of cells having coordinates in the area of real space, and maintaining a data representing inventory items matched with cells in the plurality of cells;
• and
• calculating scores at a scoring time, for inventory items having locations matching particular cells using respective counts of inventory events.

A non-transitory computer readable storage medium impressed with computer program instructions to track inventory items in an area of real space, the instructions, when executed on a processor, implement a method comprising:

• using a plurality of sensors to produce respective sequences of images of corresponding fields of view in the real space, the field of view of each sensor overlapping with the field of view of at least one other sensor in the plurality of sensors;
• identifying inventory events using the sequences of images produced by at least two sensors in the plurality of sensors;
• tracking locations of inventory items in the area of real space in response to the identification of inventory events;
• matching locations of inventory items with coordinates of cells in a plurality of cells having coordinates in the area of real space, and maintaining a data representing inventory items matched with cells in the plurality of cells;
• and
• calculating scores at a scoring time, for inventory items having locations matching particular cells using respective counts of inventory events.
