| 20080240550 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - By applying identification processing to each index included in a captured image, a set of an identifier, image coordinates, and an image number is acquired for each index, and the acquired set is registered in a data saving unit. The data saving unit manages the numbers of times of previous identification for respective identifiers. A display unit displays the number of times managed in association with an identifier in a set to be registered every time the set is registered. An index position and orientation calculation unit calculates the positions and orientations of indices corresponding to a set group using the set group registered in a memory. | 10-02-2008 |
| 20080284864 | IMAGE PROCESSING APPARATUS AND METHOD - In position and orientation measurement based on natural features, erroneous detection of the natural features is prevented when an observation target object is occluded by another object, and registration stability is improved. To this end, an occluding object that can occlude the observation target object is defined, and an occluding region where the occluding object occludes the observation target object is detected in an input captured image. Image features of the observation target object are detected in a region of the captured image other than the detected occluding region. Therefore, the position or orientation of an image pickup apparatus that captured the captured image, or the position or orientation of the observation target object in the captured image are calculated. | 11-20-2008 |

| 20100142826 | INFORMATION PROCESSING APPARATUS, PROCESSING METHOD THEREOF, AND COMPUTER-READABLE STORAGE MEDIUM - An information processing apparatus that calculates information on a position and an orientation of an image capture device relative to an object captured by the image capture device, holds three-dimensional information including a plurality of line segments that constitute the object, acquires an image of the object captured by the image capture device, detects an image feature indicating a line segment from the acquired image, calculates a position and orientation of the image capture device based on correspondence between the image feature indicating the detected line segment and the held line segment, and determines, for each of the held line segments, whether to use the line segment for the calculation of the position and orientation thereafter, based on at least one of a result of detection of the image feature, and information acquired in the calculation of the position and orientation. | 06-10-2010 |
| 20100277572 | INFORMATION PROCESSING APPARATUS AND CONTROL METHOD THEREOF - A technique for reducing the time required before a tracking process is performed again in calculating the position and orientation of an image capturing apparatus or an object. Images captured by the apparatus are acquired, the acquired images are stored in order per frame, straight lines detected in the captured images and straight lines in a three-dimensional space model are matched, the position and orientation of the apparatus are initialized by obtaining correspondences having the highest consistency, a captured image to be processed is selected from the captured images, the change in position and orientation of the apparatus is measured using the change in position and orientation of a target object in the selected image based on the initialized position and orientation of the apparatus, and if the measured change in position and orientation is not within a predetermined threshold, initialization is performed using the selected image. | 11-04-2010 |
| 20100289797 | POSITION AND ORIENTATION ESTIMATION APPARATUS AND METHOD - A position and orientation estimation apparatus detects correspondence between a real image obtained by an imaging apparatus by imaging a target object to be observed and a rendered image. The rendered image is generated by projecting a three dimensional model onto an image plane based on three dimensional model data expressing the shape and surface information of the target object, and position and orientation information of the imaging apparatus. The position and orientation estimation apparatus then calculates a relative position and orientation of the imaging apparatus and the target object to be observed based on the correspondence. Then, the surface information of the three dimensional model data is updated by associating image information of the target object to be observed in the real image with the surface information of the three dimensional model data, based on the calculated positions and orientations. | 11-18-2010 |
