Faulty cart wheel detection

摘要

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.

1. A computer-implemented method of detecting a faulty cart wheel, comprising:
receiving, at an image processing module, an image sequence depicting a cart; identifying, by the image processing module, a swiveling wheel of the cart; determining, by the image processing module, an observed oscillation frequency of the swiveling wheel; if the observed oscillation frequency exceeds an oscillation frequency threshold, transmitting, by an application server to a user computing device, an alert regarding the cart.
