Claim Text:
1. A computer system for tracking an association between two or more objects over time, the system comprising an imaging device comprising one or more cameras and one or more processors, wherein the imaging device is configured to: a. capture a first image at a first time; b. at least partially in response to capturing the first image, perform an object detection and identification analysis to detect and identify two or more objects of interest in the first image; c. at least partially in response to identifying the two or more objects of interest in the first image, determine, based at least in part on one or more object association criteria, whether the two or more objects are associated in the first image; d. at least partially in response to determining that the two or more objects are associated in the first image, store object association data for the two or more objects at the first time; e. capture a second image at a second time; f. at least partially in response to capturing the second image, detect, based at least in part on one or more change criteria, one or more changes between the first image and the second image; g. at least partially in response to detecting the one or more changes between the first image and the second image, perform the object detection and identification analysis to detect and identify the two or more objects of interest in the second image; h. at least partially in response to identifying the two or more objects of interest in the second image, determine, based at least in part on the one or more object association criteria, whether the two or more objects are associated in the second image; and i. at least partially in response to determining that the two or more objects are associated in the second image, store object association data for the two or more objects at the second time.
