| 20080292180 | POSITION AND ORIENTATION MEASUREMENT APPARATUS AND CONTROL METHOD THEREOF - A position and orientation measurement apparatus for measuring the position and orientation of an image capturing apparatus, which captures an image of a measurement object, relative to the measurement object, extracts configuration planes of the measurement object based on three-dimensional model data of the measurement object, and extracts measurement line segments to be used in detection of edges of a captured image from line segments which form the configuration planes. The position and orientation measurement apparatus projects the extracted measurement line segments onto the captured image based on an estimated position and orientation of the image capturing apparatus, selects visible measurement line segments which are not hidden by the extracted configuration planes, and calculates the position and orientation of the image capturing apparatus relative to the measurement object based on the visible measurement line segments and corresponding edges of the captured image. | 11-27-2008 |
| 20090245681 | INFORMATION PROCESSING METHOD AND INFORMATION PROCESSING APPARATUS - Markers are laid out to express a predetermined code string by a plurality of continuous markers. The markers which form a marker string include at least two types of markers having different features which can be identified by image processing. Markers detected in the captured image are converted into numerical information, and are collated based on the numerical information and the predetermined code string. Using information associated with the markers, the coordinate information of each collated marker is calculated. The position and orientation of an image capturing device are calculated using the coordinate information. With a simple arrangement, the position and orientation of an image capturing device can be calculated. | 10-01-2009 |
| 20100322517 | IMAGE PROCESSING UNIT AND IMAGE PROCESSING METHOD - An image processing unit detects a region that corresponds with a subject from a captured image sequence in which a camera and the subject move, based on the three-dimensional shape and motion of the subject. Regions included in captured images are extracted, correspondence is established between the extracted regions, the shape of the corresponding region is estimated by using three-dimensional positions of feature points in the corresponding region, rigid motion of the corresponding region is estimated by calculating motion of each feature point, and region integration or separation is performed based on the estimated rigid motion, whereby the amount of image feature miscorrespondence can be reduced. | 12-23-2010 |
| 20110164114 | THREE-DIMENSIONAL MEASUREMENT APPARATUS AND CONTROL METHOD THEREFOR - A three-dimensional measurement apparatus generates patterns to be projected onto the measurement object, images the measurement object using an imaging unit after projecting a plurality of types of generated patterns onto the measurement object using a projection unit, and computes the coordinate values of patterns on a captured image acquired by the imaging unit, based on the projected patterns, a geometric model of the measurement object, and information indicating the coarse position and orientation of the measurement object. Captured patterns on the captured image are corresponded with the patterns projected by the projection unit using the computed coordinate values, and the distances between the imaging unit and the patterns projected onto the measurement object are derived. The position and orientation of the measurement object are estimated using the derived distances and the geometric model of the measurement object, and the information on the coarse position and orientation is updated. | 07-07-2011 |
