摘要： Provided is an apparatus and method for detecting a horizon which is necessary to detect a camera movement when compositing sea images in a marker-free sea-image camera tracking system. In the method, an ROI is selected near a horizon in a still image of the moving image of the sea, and each maximum point corresponding to the maximum brightness difference is detected from brightness differences between two pixels of each pair having two symmetrical pixels in each column of the ROI. The horizon is detected through a line-fitting using the maximum points. Therefore, the result of horizon detection can be very stable and a horizon can be easily detected in a sea scene having hundreds of frames.

摘要： A system and method for supporting augmented reality in an ocean scene is provided. According to the system and method, camera rotation information is extracted from horizontal line information of a sea extracted from an original image including a focal length and at least two first natural feature point tracking data existing on a sea plane and a plane parallel to the sea plane, using long-distance background features; camera movement is sequentially calculated from the camera rotation information and at least two natural feature point tracking data existing on the sea plane of the original image; and a computer graphics object is placed on a ground plane by importing camera position data, and a rendering is performed as moving the camera. Accordingly, the camera rotation and the camera movement can be accurately calculated, assuming that the camera focal length information is known at the time of capturing a moving image with a sea image for a background, and thus the CG/real scene synthesis with the sea for a background can be accomplished more realistically and accurately during the production of videos such as movie and drama.

摘要： A high-speed marker-free motion capture, which is capable of powerfully detecting a body's feature points corresponding to a body's end portions such as a head, hands, feet, trunk, arms and legs at a high speed in an illumination change or background or noises of cameras. The extracted feature points of the body can be directly tracked stably in a 3-dimensional space. The position errors of the feature points due to the change of the illumination conditions or a shadow can be automatically corrected and the feature points can be stably tracked with respect to overlapping and disappearance of the feature points. Further, when coordinates of the middle joints are estimated using 3-dimensional coordinates of the extracted feature points of the body, the present invention restores a human model by estimating the positions of the middle joints of the actor with high accuracy without using a motion database, thereby securing the stability and reality of the 3-dimensional motion data required in the motion capture.

摘要： In a method for controlling a posture of an articulated object, a user inputs an initial configuration of the object, a base point, an end point, a target point and a method for updating the posture. It is determined whether the number of joints positioned between the base and the end points is larger than or equal to three. If the number is smaller than or equal to two, it is determined whether the method for updating the posture is a two-segment or three-segment based method or another method for moving an intermediate end point. If the method is two-segment or three-segment based, the number is rechecked. If the number is smaller than or equal to two, the posture is modified according to the two-segment or three-segment based method. If the posture satisfies a predetermined condition, it is displayed on a screen.
