Abstract
A system and method for synchronizing two-dimensional (“2D”) camera data for object recognition. An object recognition kiosk includes a plurality of 2D cameras and a stage for placement of one or more items. The plurality of 2D cameras, one of which acts as a reference camera, capture images of items on the stage from multiple angles. The system synchronizes image data from each camera in order to accurately identify items present on the stage. In situations where items in camera images fail to be linked to items identified in the reference camera perspective, the system maintains a fallback hierarchy of camera pairs to utilize to link items found in different camera images. The use of different camera pairs to link item detections continues down the fallback hierarchy until either all the item detections are linked or the last camera pair in the fallback hierarchy is reached.
