    • Under the present invention, item verification is automated and expedited. Specifically, items to be purchased can be scanned by the shopper using a barcode reader (e.g., a scanner) attached to or positioned near the shopping receptacle. As items are scanned, they are identified based on their barcode and added to an item list. Item verification can then performed at checkout using imaging technology. For example, the shopping cart or shopping basket can be brought into the field of view of a computer-connected camera. The camera and computer can, working from the customer's item list developed when the items are scanned, observe each product in the receptacle and “ring it up”. If all products can be accounted for, the customer is free to leave; otherwise the customer is denied egress, informed of the problem, etc. A store employee can also be signaled to investigate. The total time required to make the decision is the time to take a picture and process it, which by human standards is very fast; faster than existing verification methods.
    • 在本发明中,项目验证是自动化和加速的。 特别地,购物者可以使用附接到购物容器附近或位于购物容器附近的条形码读取器(例如,扫描器)来扫描要购买的物品。 当项目被扫描时,它们根据其条形码被识别并被添加到项目列表中。 然后可以使用成像技术在结帐时执行项目验证。 例如,购物车或购物篮可以被带入计算机连接的相机的视野中。 照相机和计算机可以在扫描物品时开发的客户项目列表中进行操作,观察插座中的每个产品并“振铃”。 如果所有产品都可以核算,客户可以自由离开; 否则客户被拒绝出境,通知问题等。店员也可以被告知调查。 作出决定所需的总时间是拍摄照片和处理时间,人体标准非常快; 比现有的验证方法快。
