Systems and methods for determining measurement data of an item

Abstract

Provided are a system and method for determining a weight of an item for purchase, comprising determining from a digital image of an item generated by a single camera, a volume of the item, the single camera separated from the item at a distance in a horizontal and vertical direction established by a stationary rigid fixture; identifying the item; accessing a database to determine an average weight per volume measurement unit of the identified item; and calculating a weight of the item from the volume and the average weight per volume measurement unit.

What is claimed is: 
     
         1 . A system for determining a weight of an item for purchase, comprising:
 a single camera that generates a digital image of the item;   at least two mirrors for determining an average volume of the item;   an optical recognition device that identifies the item;   a memory that stores an average weight per volume measurement unit of the identified item; and   a special-purpose processor that calculates an estimated weight of the item from the approximate volume and the average weight per volume measurement unit.   
     
     
         2 . The system of  claim 1 , wherein the at least two mirrors are arranged to provide a front view, a right view, and a left view of the image. 
     
     
         3 . The system of  claim 1 , further comprising a volume calculator that determines an area of the item from each of the front view, the right view, and the left view of the image, and determines an average of the three areas. 
     
     
         4 . The system of  claim 3 , wherein the volume calculator determines an average depth of the image for determining the volume. 
     
     
         5 . The system of  claim 3 , further comprising an optical recognition device that identifies the produce item, and wherein the weight of the produce item is determined from a result of the optical recognition device and the volume. 
     
     
         6 . A method for determining a volume and weight of a produce item, comprising:
 extrapolating a length, width, and depth of a produce item from a two-dimensional image of the produce item;   determining a volume from a combination of the length, width, and depth of the produce item; and   determining a weight of the item from the volume.
