Abstract
This disclosure is directed to an item-identifying cart that may be utilized by a user in a materials handling facility to automatically identify items that the user places in their cart, and update a virtual shopping cart to include items taken by the user. The mobile cart may include four capture assemblies that are disposed proximate to each of the four corners of a basket of the cart, and oriented such that their respective optical axes are directed towards an interior of a perimeter of the top of the basket, and above the top of the basket. The capture assemblies may include proximity sensors that are used to detect movement above the top of the basket, LEDs that illuminate items, and cameras that generate image data representing the items as they are placed in, or removed from, the cart.
