System and Method for Locating, Identifying and Counting Items
First Claim
Patent Images
1. A inventory monitoring method, comprising the steps of:
- detecting and reading shelf labels on at least one shelf;
defining one or more bounding boxes around potential inventory in an image taken with at least one camera; and
associating the bounding boxes in the image to shelf labels to build at least one of a product classifier or a product library.

Abstract
A system for building a product library without requiring a planogram includes an image capture unit operated to provide images of items. Taking data from a shelf label detector and depth map creation unit, a processing module can be used to compare detected shelf labels to a depth map, define a product bounding box, and associate the bounding box with an image provided by the image capture unit to build image descriptors. The system can include one or more autonomous robots for supporting and moving the image capture unit and other components.

11. A system for building a product classifier, comprising:
-
an image capture unit; a shelf label detector and reader to capture shelf label data; a processing module to define multiple bounding boxes, and a trainable image classifier to associate images within the bounding boxes with the shelf label data, the images being provided by the image capture unit. - View Dependent Claims (12, 13, 14)

15. A inventory monitoring method, comprising the steps of:
-
detecting and reading shelf labels; detecting distance from at least one camera to at least one shelf; defining bounding boxes around potential inventory in an image taken with at least one camera; and associating selected bounding boxes in the image to selected shelf labels to build at least one of a product classifier or a product library. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
