A camera system for inventory monitoring includes a movable base that supports multiple cameras. The multiple cameras are directed toward inventory to take a series of pictures along aisle of a retail store or warehouse. A processing module connected to the multiple cameras is used to stitch together the pictures, and along with depth information and product identification information, construct a real time or near real time inventory mapping of products positioned on aisle shelves. This information can be transferred to remote locations to simplify and speed product ordering, and assist in maintenance of appropriate product stock levels.
