Abstract

Methods and systems for developing shelf product location and identification layout for a retail environment. Such an approach can include a mobile base navigable throughout the retail environment, at least one camera mounted on the mobile base acquiring images of aisles, shelving, and product located on the shelving throughout the retail environment; and a computer controlling mobile base movement, tracking mobile base location and orientation, and organizing images acquired by the camera including facing information for product associated with shelving and aisles as images are acquired and input to the computer to generate plane-like panoramas representing inventory, inventory location, and layout of the retail environment.

First claim

1 . A navigable imaging system for developing shelf product location and identification layout for a retail environment, comprising:
a mobile base navigable throughout the retail environment; at least one camera mounted on said mobile base acquiring images of aisles, shelving, and product located on the shelving throughout the retail environment; and a computer controlling mobile base movement, tracking mobile base location, and orientation, and organizing images acquired by said at least one camera including facing information for product associated with shelving and aisles as images are acquired and input to the computer to generate plane-like panoramas representing inventory, inventory location, and layout of the retail environment.

2 . The navigable imaging system for developing shelf product location and identification layout for a retail establishment of claim 1 , wherein acquired images represent a plane-like panorama of each aisle and associated shelving in the retail environment.

3 . The navigable imaging system for developing shelf product location and identification layout for a retail establishment of claim 2 , wherein each panorama is a snapshot of each aisle and associated shelving in the retail environment.

4 . The navigable imaging system for developing shelf product location and identification layout for a retail establishment of claim 2 , wherein said images of each aisle are processed and organized based on aisle location within the store, shelving location within aisles and product carried on shelving, and said images ordered for shelf-product layout identification and planogram compliance.

5 . The navigable imaging system for developing shelf product location and identification layout for a retail establishment of claim 2 , wherein said images are used for constructing a model-based plane-like panorama of store-shelf for various retail applications including at least one of: as planogram for shelf-product layout within the store, compliance, misplaced item defection, inventory management, and support of virtual shopping with the retail environment.

6 . The navigable imaging system: for developing shelf product location and identification layout for a retail establishment of claim 5 , wherein the model is derived based on knowledge of imaging configuration and the tracked mobile base location.

7 . The navigable imaging system for developing shelf product location and identification layout for a retail establishment of claim 5 , wherein the model is further refined based on the tracked mobile base orientation.

8 . The navigable imaging system for developing shelf product location and identification layout for a retail establishment of claim 5 , wherein the model is represented in the form of at least one look-up table for efficient real-time computation.

9 . The navigable imaging system for developing shelf product location and identification layout for a retail establishment of claim 5 , wherein interpolation is conducted among look-up tables based on tracked mobile base orientation and calculated distance to the shelf.

10 . The navigable imaging system: for developing shelf product location and identification layout for a retail establishment of claim 5 , wherein the generation of model-like plane-like panorama further comprises refining the stitching of acquired images based on the image content similarity near the border of the images from consecutive imaging locations.

11 . A method of capturing and organizing images for developing shelf product location and identification layout of a retail environment, comprising:
provide an imaging system that will navigate and acquire images and determine location of aisles, shelving, and inventory on the shelving throughout a retail environment; track location and facing information of inventory located on the shelving; and input images into a computer to generate plane-like panoramas representing inventory, inventory location, and layout of inventory within the retail environment.

12 . The method of capturing and organizing images for developing shelf product location and identification layout of a retail environment of claim 11 , wherein acquired images represent a plane-like panorama of each aisle and associated shelving in the retail environment.

13 . The method of capturing and organizing images for developing shelf product location and identification layout of a retail environment of claim 11 , wherein each panorama is a snapshot of each aisle and associated shelving in the retail environment.

14 . The method of capturing and organizing images for developing shelf product location and identification layout of a retail environment of claim 11 , wherein said images of each aisle are processed and organized based on aisle location within the retail environment, shelving location within aisles and product carried on shelving, and said images ordered for shelf-product layout identification and planogram compliance.

15 . The method of capturing and organizing images for developing shelf product location and identification layout of a retail environment of claim 11 , wherein said images are used for constructing model-based plane-like panorama of store-shelf for various retail applications including at least one of: as planogram for shelf-product layout within the store, compliance, misplaced item detection, inventory management, and support of virtual shopping with the retail environment.

16 . A navigable imaging system for developing shelf product location and identification layout for a retail environment, comprising:
a mobile base including at least one camera mounted thereon; at least one microprocessor coordinating module activity; a navigation module controlling the movement of the mobile base; an image acquisition module controlling image acquisition by said at least one camera as the mobile base navigates through the retail environment; a characterization module determining spatial characteristics of the navigable imaging system as it moves throughout a retail environment and said at least one camera acquires images of aisles and associated shelving; a vertical spatial look-up-table generation module generating at least one spatial look-up-table (LUT) for use in developing 2D plane-like panoramas of aisles in a vertical direction; a system pose receiving module receiving corresponding system pose information, including imaging system location, distance, and orientation to a shelf plane as images are acquired; and a model-based panorama generation module generating 2-D plane-like panoramas for each aisle utilizing the acquired images, the system pose information, the at least one spatial LUT, and storing the generated panoramas representing aisles, shelving, and product located throughout the retail environment.

17 . A navigable imaging system for developing shelf product location and identification layout for a retail establishment of claim 16 , wherein acquired images represent a plane-like panorama of each aisle and associated shelving in the retail environment.

18 . A navigable imaging system for developing shelf product location and identification layout for a retail establishment of claim 16 , wherein each panorama is a snapshot of each aisle and associated shelving in the retail environment.

19 . A navigable imaging system for developing shelf product location and identification layout for a retail establishment of claim 16 , wherein said images of each aisle are processed and organized based on aisle location within the retail environmen
