Patent attributes
A method and system for associating an image of a face of at least a person with Point-of-Sale (PoS) data by aligning a first event time series with a second event time series based on a dynamic time disparity. An exemplary embodiment can generate an event time series containing facial recognition data for a person or persons during the PoS transaction process. These data can form a vision-based checkout event time series. An embodiment can also collect PoS transaction data from the retail checkout system, using timestamp information to create a second event time series. As there may be a time disparity between the time series, they can then be aligned in order to match events from one time series to the other. Faces identified in checkout events in the first time series can be registered to PoS events and the results stored in a database.
