Abstract

Methods and apparatus to survey a retail environment are disclosed herein. A disclosed example method involves moving a cart in a retail establishment having a camera. The method also involves capturing a first image of a first area and a second image of a second area. A stitched image is generated based on the first and second images. The stitched image is associated with product codes based on products appearing in the stitched image.

Claims

1. A method, comprising:

moving a cart in a retail establishment, wherein the cart includes at least one camera mounted on the cart;

capturing a first image of a first area and a second image of a second area;

generating a stitched image based on the first and second images; and

associating the stitched image with product codes based on products appearing in the stitched image.

2. A method as defined in claim 1, wherein generating the stitched image based on the first and second images comprises:

identifying a first region of the first image that is substantially similar to a second region of the second image;

overlaying the first region onto the second region; and

merging the first and second images via the overlaid first and second regions.

3. A method as defined in claim 1, further comprising measuring a distance from the example cart to a target area in a field of view of the camera.

4. A method as defined in claim 1, further comprising generating location information indicative of a location at which the first image was captured and storing the location information in association with the first image.

5. A method as defined in claim 4, wherein generating the location information comprises collecting rotary encoder measurement information indicative of a travel of a wheel of the cart and generating the location information based on the rotary encoder measurement information.

6. A method as defined in claim 1, wherein the stitched image is representative of a shelving unit in the retail establishment.

7. A method as defined in claim 1, further comprising tagging each of the images of the stitched image with location information indicative of the locations at which the images were captured in the retail establishment.

8. A method as defined in claim 1, further comprising storing categorical zone information in association with at least one of the first image or the second image, wherein the categorical zone information is indicative of products or services corresponding to the contents of the at least one of the first image or the second image.

9. A method as defined in claim 1, further comprising displaying at least one of the first image or the second image via a user interface, receiving user input via the user interface, and storing information in association with at least one of the first image or the second image based on the user input.

10. A method as defined in claim 9, wherein receiving the user input involves receiving the user input via a drag and drop event.

11. A method as defined in claim 1, further comprising displaying a speed indicator indicative of the speed of the cart.

12. A method as defined in claim 1, further comprising displaying a path of travel of the cart indicative of locations traveled by the cart in the retail establishment.

13. A method as defined in claim 12, further comprising displaying a layout map of the retail establishment and displaying the path of travel in association with the layout map.

14. A method as defined in claim 1, further comprising discarding first and second portions of the first image and third and fourth portions of the second image prior to generating the stitched image.

17. An apparatus, comprising:

a camera interface to receive a first image of a first area and a second image of a second area from at least one camera, wherein the at least one camera is mounted on a cart;

an image merger to generate a stitched image based on the first and second images; and

a product code associator to associate the stitched image with product codes based on products appearing in the stitched image.

18. An apparatus as defined in claim 17, further comprising an image features detector to identify a first region of the first image that is substantially similar to a second region of the second image, wherein the image merger is to overlay the first region onto the second region and merge the first and second images via the overlaid first and second regions.

19. An apparatus as defined in claim 17, further comprising measuring a distance from the example cart to a target area in a field of view of the camera.

20. An apparatus as defined in claim 17, further comprising:

a location information generator to generate location information indicative of a location at which the first image was captured; and

a data interface to store the location information in association with the first image.

23. An apparatus as defined in claim 17, further comprising a data interface to store location information in association with each of the images of the stitched image indicative of the locations at which the images were captured in the retail establishment.

24. An apparatus as defined in claim 17, further comprising a zone associator to associate categorical zone information in association with at least one of the first image or the second image, wherein the categorical zone information is indicative of products or services corresponding to the contents of the at least one of the first image or the second image.

25. An apparatus as defined in claim 17, further comprising:

a display interface to display at least one of the first image or the second image via a user interface;

a user input interface to receive user input via the user interface; and

a data interface to store information in association with at least one of the first image or the second image based on the user input.

28. An apparatus as defined in claim 17, wherein the display interface is further to display a path of travel of the cart indicative of locations traveled by the cart in the retail establishment.

29. An apparatus as defined in claim 28, wherein the display interface is further to display a layout map of the retail establishment and display the path of travel in association with the layout map.

32. An apparatus as defined in claim 17, wherein the at least one camera is mounted on the cart in an outwardly facing configuration toward a field of view substantially perpendicular to the direction of travel of the cart.

33. A machine accessible medium having instructions stored thereon that, when executed, cause a machine to:

detect movement of a cart in a retail establishment, wherein the cart includes at least one camera mounted on the cart;

capture a first image of a first area and a second image of a second area;

generate a stitched image based on the first and second images; and

associate the stitched image with product codes based on products appearing in the stitched image.
