<P>PROBLEM TO BE SOLVED: To securely identify an object to be identified without causing troublesome work even when the shape and the disposition position of the object to be identified are different. <P>SOLUTION: On a delivery item conveyed on a conveyer 10, a plurality of marks having mutually different hues are arrayed, and a color code representing code information by the arrayed sequence of the plurality of marks is added. An identification system includes a camera 20 fixedly mounted adjacent to the conveyer 10, a code extraction section 31 for acquiring the image of the delivery item, imaged by the camera 20, and for extracting the color code from the above image, and a code recognition section 32 for decoding the code information represented by the color code extracted by the code extraction section 31. <P>COPYRIGHT: (C)2009,JPO&INPIT |
