Abstract: A delivery management server, connected over a network to a user terminal used by a receiver who is a delivery destination of a delivery object or a carrier who delivers the delivery object, includes registration means for writing identification information of the delivery object and a first image in which a random pattern on a surface of the delivery object is captured, into a storage means in association with each other; matching means for performing matching between a second image in which a random pattern on a surface of the delivery object is captured, received from the user terminal, and the first image stored in the storage means; and confirmation recording means for, based on the matching result, recording, on the storage means, confirmation information that gives a confirmation that the user of the user terminal received the delivery object identified by the identification information associated with the first image.

Abstract: An object management system includes an acquisition means for acquiring an image in which a surface of a registration target object, having a circle and a handwritten character drawn thereon, is captured, a generation means for detecting an ellipse corresponding to the circle from the image and generating a registration image in which the image is applied with projective transformation such that the ellipse becomes a circle, and a registration means for writing the registration image into a storage means as data for determining the sameness of the registration target object.

Abstract: The present invention relates to an information processing device used in an image capture device that illuminates an object with an illuminating unit and images light reflected from the object as a reflection image with an imaging unit. The information processing device includes an irradiation angle determining unit configured to determine an irradiation angle when the illuminating unit illuminates the object based on a tilt statistic that is a value corresponding to tilt distribution of irregularities formed on the surface of the object.

Abstract: A registration means for storing an image of a product as a registration image in association with information representing the passing sequence that the product passed through an upstream side process; a management means for managing the matching sequence in a downstream side process; and a matching means for performing matching between an image of a product carried into the downstream side process and the registration image according to the matching sequence, are included. Each time the matching means succeeds in matching, the management means updates the matching sequence to sequence in which registration images not having succeeded in matching with any matching image are put in order on the basis of the passing sequence that the products passed through the upstream side process.
