A system, method, and computer program product for managing a physical inventory. Image data from a number of cameras is processed to recognize inventory items from identifying indicia and determine their respective locations to build a three-dimensional model of the inventory item distribution. Comparison with a database model of the inventory item distribution may indicate discrepancies, such as misplaced items. A picking agent may be dispatched to pick a target item by following a particular path, which may be designated in an overlay on a portable heads-up display. The picking agent may also perform a corrective inventory management action on a non-target item while picking the target item. The corrective inventory management action may include repositioning an item, reorienting the item for better visibility of its identifying indicia, replacing the item's identifying indicia, determining if the item is of expected weight, and gathering new image data.
