Abstract
Image-based object representation (OR) tracking of users or other objects in a facility may occasionally lose the identity associated with a particular OR. For example, in a crowded aisle the respective ORs for individual users may merge, resulting in a loss of identity of the particular OR. As the crowd dissipates, confidence in the identity of a particular OR may be low. In one implementation, image processing is used to determine OR movement data descriptive of the time(s) when the OR is in motion or stopped. Device movement based on data acquired by sensors on a mobile device carried by a user is descriptive of when the mobile device is in motion or stopped. A match between the particular OR movement data and the particular device movement data allows the identity of the particular OR to be determined as an identity associated with the mobile device.
