System and method of object tracking using weight confirmation
First Claim
Patent Images
1. A method for tracking an object, comprising:
- capturing images of a surface;
obtaining identification information associated with an object;
expecting, in response to obtaining the identification information associated with the object, activity involving placement of the object on or removal of the object from the surface to appear next in the captured images;
associating a change in the captured images that is first to be detected after obtaining the identification information with the activity involving placement of the object on or removal of the object from the surface;
measuring a change in weight at a location on the surface;
comparing where on the surface the change appears in the captured images with the location on the surface where the change in weight is measured; and
confirming, in response to the comparison, that the activity involving placement of the object on or removal of the object from the surface has appeared next in the captured images, as expected, and has occurred on the surface where the change appears in the captured images.

Abstract
Methods and systems for tracking an object comprise a horizontal surface upon which objects are to be placed, a weight sensor disposed on one side of the horizontal surface, and a processor in communication with the weight sensor. The processor is adapted to detect a change in weight measured by the weight sensor, to associate the detected weight change with an identified object and with a location on the horizontal surface, and to confirm whether a cause of the weight change at the location on the horizontal surface corresponds to a proper handling of the identified object.

1. A method for tracking an object, comprising:
-
capturing images of a surface; obtaining identification information associated with an object; expecting, in response to obtaining the identification information associated with the object, activity involving placement of the object on or removal of the object from the surface to appear next in the captured images; associating a change in the captured images that is first to be detected after obtaining the identification information with the activity involving placement of the object on or removal of the object from the surface; measuring a change in weight at a location on the surface; comparing where on the surface the change appears in the captured images with the location on the surface where the change in weight is measured; and confirming, in response to the comparison, that the activity involving placement of the object on or removal of the object from the surface has appeared next in the captured images, as expected, and has occurred on the surface where the change appears in the captured images. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. An object tracking system comprising:
-
a camera that captures images of a surface; a scanning device that obtains identification information associated with an object; a processor configured to; obtain the identification information associated with the object from the scanning device; expect, in response to obtaining the identification information associated with the object, activity involving placement of the object on or removal of the object from the surface to appear next in the captured images; and associate a change in the captured images that is first to be detected after the processor obtains the identification information with the activity involving placement of the object on or removal of the object from the surface; and a sensor that measures a change in weight at a location on the surface, wherein; the processor further configured to; compare where on the surface the change appears in the captured images with the location on the surface where the change in weight is measured; and confirm, in response to the comparison, that the activity involving placement of the object on or removal of the object from the surface has appeared next in the captured images, as expected, and has occurred on the surface where the change appears in the captured images. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
