Agent re-verification and resolution using imaging

A computing system, comprising:

• one or more processors;
• and
• a memory coupled to the one or more processors and storing program instructions that, when executed by the one or more processors, cause the one or more processors to at least:
• generate a first agent model corresponding to at least a portion of a first agent;
• track a position of an object corresponding to the first agent as the object moves around within a materials handling facility;
• during the tracking, determine that the position of the object has been dropped;
• in response to determination that the position of the object has been dropped, add a first object identifier corresponding to the object to a drop list;
• and
• subsequent to addition of the first object identifier to the drop list:
• determine a second agent model representative of at least a portion of a second agent;
• determine that the second agent model corresponds to the first agent model;
• and
• in response to determination that the second agent model corresponds to the first agent model, associate the first agent model with a second object that is being tracked, wherein the second agent model is generated based at least in part on the second object.

A method, comprising:

• receiving image data from one or more image capture devices located within a materials handling facility;
• generating, based at least in part on the image data, a first agent model that includes a first plurality of feature vectors representative of a first agent represented in at least a portion of the image data;
• subsequent to generating the first agent model, determining that a position of the first agent has been dropped;
• in response to determining that the position of the first agent has been dropped, adding a first identifier corresponding to the first agent model to a drop list;
• subsequent to adding the first identifier to the drop list:
• determining a second agent model representative of at least a portion of a second agent;
• determining that the second agent model corresponds to the first agent model;
• and
• in response to determining that the second agent model corresponds to the first agent model, associating the first agent model with a second agent model;
• and
• updating an item list corresponding to the second agent model to include an item identifier of an item picked by the first agent.
