20090110241 | IMAGE PROCESSING APPARATUS AND METHOD FOR OBTAINING POSITION AND ORIENTATION OF IMAGING APPARATUS - An image processing apparatus obtains location information of each image feature in a captured image based on image coordinates of the image feature in the captured image. The image processing apparatus selects location information usable to calculate a position and an orientation of the imaging apparatus among the obtained location information. The image processing apparatus obtains the position and the orientation of the imaging apparatus based on the selected location information and an image feature corresponding to the selected location information among the image features included in the captured image. | 04-30-2009 |
20090129677 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - For each image sensing device, an index in a sensed image is recognized, and layout information of the recognized index in a coordinate system based on an image sensing device that has acquired the sensed image is calculated. Index information including identification information unique to the index and the layout information of the index is managed. If recognition of a first index in a first sensed image acquired by a first image sensing device has failed, or the first index has erroneously been recognized, the index information of the first index is varied on the basis of the layout information of the first index calculated by the above process for a second sensed image acquired by a second image sensing device other than the first image sensing device. | 05-21-2009 |
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 |
