摘要： Disclosed are a method and apparatus for measuring rotation characteristics such as rotation rate, rotation axis, and rotation angle of a rotating body. A method of measuring rotation characteristics includes extracting a rotating-body region from an image of the rotating body; extracting a surface pattern of the rotating body on the basis of brightness values of the extracted rotating-body region and acquiring rotation characteristics of the rotating body on the basis of change in the extracted surface pattern. Accordingly, it is possible to accurately measure rotation characteristics regardless of variation in brightness values of a surface region of the rotating body depending on illumination of a lamp, sensitivity of a camera, and exposure time of a camera.

摘要： Disclosed is a method of simulating a collision trajectory of a ball which rotates and moves in a virtual sports game (for example, golf, baseball, soccer, or tennis). A method of collision simulation for a spinning ball includes: detecting collision of a spinning ball; calculating a velocity of the ball after colliding considering rotation of the ball and the friction with the ground; calculating a center point of the ball after colliding; and rolling and stopping the ball. The detecting of collision of a spinning ball includes: checking whether a segment connecting a center point in a previous position of the ball and a center point in the current position collides with the ground; and generating vectors of a lower part of the ball to check whether the vectors collide with the ground.

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.
