Abstract:
A system and method of identifying carts exhibiting tendencies that are indicative of damaged or defective wheels. A shopping cart may be identified and tracked visually through one or more surveillance cameras. By comparing the cart's tracked movement to known symptomatic movement patterns, the system may identify defective or damaged carts. Alternatively, by analyzing movement and positioning of a cart's swiveling wheels, the system may identify defective or damaged carts. Alternatively, by identifying if a customer has abandoned a cart, the system may identify defective or damaged carts. A notification message may be transmitted to an associate to repair or replace the identified problematic cart. The notification may be displayed on a mobile computing device, a workstation, or other like systems.
