Abstract: Markers may be presented on different objects in a facility, such as shelves or totes. A marker can use color, placement of elements, blending effects, or infrared light layers to encode data about the object. During operation, a camera within the facility may acquire an image, which includes an image of the marker as presented on the object. The marker can be analyzed to detect marker data encoded therein. By decoding the marker data, details about the marker can be extracted, such as an identification of the object. In addition, using details about the marker location within the image and location data associated with the camera, a location of the object relative to the camera can be determined, as well as an orientation of the object relative to the camera. As the object moves within the facility, the object can be tracked based on this location and orientation data.

Abstract: Described is a multiple-camera system and process for detecting a user within a materials handling facility and tracking a position of the user as the user moves through the materials handling facility. In one implementation, a plurality of depth sensing cameras are positioned above a surface of the materials handling facility and oriented to obtain a top-down view of the surface of the materials handling facility, along with any objects (e.g., users) on the surface of the materials handling facility. The depth information from the cameras may be utilized to detect objects on the surface of the materials handling facility, track a movement of those objects and determine if those objects are users.

Abstract: This disclosure describes a system for disambiguating between multiple potential users that may have performed an item action (e.g., item removal or item placement) at an inventory location. For example, if there are three picking agents (users) standing near an inventory location and one of the agents removes an item (item action) from the inventory location, the example systems and processes described herein may utilize various inputs to disambiguate between the users and determine which of the potential users performed the item action.
