20110148875 | METHOD AND APPARATUS FOR CAPTURING MOTION OF DYNAMIC OBJECT - The present invention relates to a method and apparatus for capturing a motion of a dynamic object, and restore appearance information of an object making a dynamic motion and motion information of main joints from multi-viewpoint video images of motion information of a dynamic object such as a human body, making a motion through a motion of a skeletal structure on the basis of the skeletal structure, acquired by using multiple cameras. According to the exemplary embodiments of the present invention, it is possible to restore motion information of the object making a dynamic motion by using only an image sensor for a visible light range and to reproduce a multi-viewpoint image by effectively storing the restored information. Further, it is possible to restore motion information of the dynamic object without attaching a specific marker. | 06-23-2011 |

20120162412 | IMAGE MATTING APPARATUS USING MULTIPLE CAMERAS AND METHOD OF GENERATING ALPHA MAPS - Disclosed herein are an image matting apparatus using multiple cameras and a method of generating alpha maps. The apparatus includes a multi-camera unit, a depth estimation unit, an alpha map estimation unit, and an image matting unit. The multi-camera unit acquires a main image generated when a main camera captures an object at a specific camera angle, and acquires a plurality of sub-images generated when a sub-camera captures the object at different camera angles. The depth estimation unit estimates a depth value, corresponding to a distance between the main camera and the object, for each cluster. The alpha map estimation unit estimates an alpha map of the main image using the depth value estimated by the depth estimation unit. The image matting unit extracts a foreground from the main image using the alpha map, and performs image matting using the extracted foreground. | 06-28-2012 |
20130016223 | METHOD AND APPARATUS FOR CAMERA NETWORK CALIBRATION WITH SMALL CALIBRATION PATTERNAANM KIM; Jae HeanAACI DaejeonAACO KRAAGP KIM; Jae Hean Daejeon KRAANM Kang; HyunAACI DaejeonAACO KRAAGP Kang; Hyun Daejeon KRAANM Lee; Ji HyungAACI DaejeonAACO KRAAGP Lee; Ji Hyung Daejeon KRAANM Koo; BonkiAACI DaejeonAACO KRAAGP Koo; Bonki Daejeon KR - A method for calibrating a camera network includes generating a projection matrix by each of cameras in respect of a calibration pattern that is disposed at a plurality of different positions in a photography zone. A portion of the projection matrix is produced as a sub-projection matrix. Sub-projection matrixes are arranged widthwise and lengthwise to generate one sub-measurement matrix. A singular value decomposition (SVD) is performed on the sub-measurement matrix to change the sub-measurement matrix into a matrix having a rank of 3 and a SVD is performed on the changed sub-measurement matrix. A rotation value of the calibration pattern, and an internal parameter and a rotation value of each camera are extracted to thereby calibrate the camera network. | 01-17-2013 |
