Abstract: In a feature matching method for recognizing an object in two-dimensional or three-dimensional image data, features in each of which a predetermined attribute in the two-dimensional or three-dimensional image data takes a local maximum and/or minimum are detected, and features existing along edges and line contours from the detected features are excluded. Thereafter, the remaining features are allocated to a plane, some features are selected from the allocated features by using local information, and feature matching for the selected features being set as objects is performed.

Abstract: A plurality of known markers is disposed in a specific district. A marker detection section detects the known markers existing in the image photographed by an image pickup device. A position/orientation relation calculation section identifies the detected known marker to calculate position and orientation relations between the identified known marker and the image pickup device. An associated information obtaining section obtains predetermined information associated with the identified known marker. An information processing section processes the obtained predetermined information based on the calculated position and orientation relations. A display device superimposes and displays the processed information on the photographed image. At least the image pickup device and display device are disposed in a portable information terminal, and the other sections are disposed in a server which can perform radio communication with the portable information terminal.

Abstract: An information presentation method is to photograph an object by use of an image input device and display related information corresponding to the object on the object in a display screen or the periphery of the object in the display screen. The related information of the object is expressed by the contents of expression of a plurality of two-dimensional markers set on the object or the periphery of the object and the plurality of two-dimensional markers correspond to any one of a plurality of information series.

Abstract: Image information is input by an image input unit, a marker is extracted from an image of the input image information by a marker detector, a position of the extracted marker in the image is detected by a position/posture detector, and the difference between indicators extracted from images is judged. At this time, the position/posture detector is provided with a judgment condition based on the position of each marker, as a judgment condition that is at least selectively applied.

Abstract: A three-dimensional position posture relation detection unit detects a relation of relative three-dimensional position and posture between an image input unit and a target object using the image of the target object in a real space input from the image input unit. A difference comparison detection unit compares the detected position and posture of the target object and a value stored in a figuration information storage unit corresponding to a part of the target object so as to detect a difference between an actual position and posture of the input target object and stored figuration information of the target object. A figuration information management unit reflects a value of the detected difference on figuration information stored in the figuration information storage unit. A superposed image generation unit generates an image which is obtained by superposing the image of the input target object and stored figuration information of the target object.

Abstract: Based on an image input by an image input section (11), a mobile application (13) and a matching process section (21) use templates managed in a hierarchical manner to search a TP data management DB (22) for an image. At this time, the mobile application (13) and matching process section (21) perform template matching using a higher level hierarchical template (e.g., 1st-level hierarchical template 2221) and subsequent template matching using a lower level hierarchical template (e.g., 2nd-level hierarchical template 2222) to narrow down the number of images to be searched for and display images as narrowed down search results.
