  • Publication number: 20110194776
    Abstract: Provided are a collating device, a processing method and a collation program, in which a reference line is extracted from an image and each partial image is moved in a manner that the reference line becomes a predetermined one thereby to correct the image, and in which the corrected image is collated so that an authentication result can be obtained for a short time period without any rotating operation. At first, a reference line extracting unit extracts the center line or the contour line of the image as the reference line. Next, an image correcting unit moves each partial image in parallel thereby to correct the image so that the reference line obtained by the reference line extracting unit becomes a predetermined one. Moreover, an image collating unit collates the image corrected by the image correcting unit and a predetermined image to acquire an authentication result.

  • Patent number: 7703396
    Abstract: In a curve section, a comb tooth mark 28 is provided concentrically with a center line 44 of a running rail 4. A comb tooth sensor 34 on an overhead running vehicle 2 reads comb teeth 40. Then, corrections are made using the ratio of the radius of curvature (R) of the center line 44 and the radius of curvature (r) of the comb tooth mark 28. An encoder interpolates the areas between the teeth 40. Then, the position of the overhead running vehicle 2 in the curve section is determined. The present invention thus enables the exact position of the overhead running vehicle 2 to be recognized even when the overhead running vehicle 2 is located in a curve section. This makes it possible to provide a load port in a curve section.
