  • Patent number: 7239718
    Abstract: 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.

  • Patent number: 6768489
    Abstract: 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.
