Abstract: An information processing device, to be used in an image capturing device that illuminates an object by an illumination means and captures reflected light from the object as a reflection image by a capturing means, includes a determination means for determining an irradiation angle range for irradiating the object by the illumination means, on the basis of two types of inclination statistic values that are values corresponding to the inclination distribution of the unevenness existing on a surface of the object.

Abstract: An object matching device includes an acquiring unit, an extracting unit, and a determining unit. The acquiring unit acquires an image of an object to be matched with a character printed thereon. The extracting unit extracts a partial image of predetermined size including the character as a matching partial image from the image. The determining unit compares the matching partial image with a registration partial image acquired from an object to be registered and registered in advance, and thereby determines an identity of the object to be matched and the object to be registered.

Abstract: The present invention reduces the time and cost to manage found objects, and comprises: a sale information acquisition unit which, if an object is sold, acquires a first object identifier identifying the sold object, and acquires ownership rights surrender information indicating that ownership rights to the sold object are surrendered if the buyer loses the sold object; a recording unit which associates and records the first object identifier with the ownership rights surrender information; a found information acquisition unit which acquires a second object identifier identifying a found object; a comparison unit which compares the second object identifier and the first object identifier; and a notification unit which, if the second object identifier and the first object identifier match, sends a notification that the ownership rights to the found object have been surrendered.

Abstract: Provided is a position determination device including: a comparison unit that is configured to compare a random pattern of an image of a partial area of a ceiling or a floor, the image being captured by a mobile terminal, with a random pattern of an image of an extensive area of the ceiling or the floor, the extensive area of the ceiling or the floor being more wider than the partial area of the ceiling or the floor; determine a position of the image of the partial area in the image of the extensive area, and determine the position on the ceiling above the mobile terminal or the position on the floor below the mobile terminal based on the determined position on the image of the extensive area.

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: When there is an image component common to multiple registered images, the accuracy of individual identification lowers. A decision unit decides, for each partial area, the degree of effectiveness relating to calculation of a score representing a similarity between a registered image obtained by capturing an object to be registered and a collated image obtained by capturing an object to be collated, based on whether or not the partial area contains an image component common to multiple registered images obtained by capturing multiple objects to be registered. A calculation unit calculates the score based on image components contained in the registered image and the collated image and on the degrees of effectiveness.
