1. An apparatus for recognizing a three-dimensional (3D) motion using Linear Discriminant Analysis (LDA), comprising:

  • a 3D motion capturing means for creating motion data for every motion by using a marker-free motion capturing process for a motion of an actor;

    a motion recognition learning means for analyzing the created motion data on multiple types of motions using the LDA, creating a linear discrimination feature component for discriminating corresponding motion data, extracting/storing a reference motion feature on each type of motions based on the created linear discrimination feature component, and recognizing each of the extracted/stored reference motion features as a corresponding motion; and

    a motion recognition operating means for extracting a motion feature based on the created linear discrimination feature component from motion data on an input motion to be the created 3D recognition object, searching a reference motion feature corresponding to the extracted input motion feature among the stored reference motion features, and recognizing a motion corresponding to the searched reference motion feature as a 3D motion on the input motion.
