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.

Disclosed are an apparatus and a method for measuring a speed of a rotation body and recognizing a spin using a line scan. The present invention provides an apparatus and a method for calculating a motion of an object capable of acquiring line scan images using some lines of an area scan camera and calculating a three-dimensional speed and a three-dimensional spin of a rotation body by using a composite image in which the line scan images are coupled. The present invention can provide a realistic game or training at low cost by providing realistic physical simulation of the rotation body while allowing a competitive price when producing products by using the existing inexpensive camera.

Disclosed is a method for automatically extracting centroids and features of a spherical object required to measure a flight speed, a flight direction, a rotation speed, and a rotation axis of the spherical object in a system for measuring flight information of the spherical object with a high-speed stereo camera.In order to automatically extract the centroids and the features of the spherical object, the present invention may automatically extract the centroid and the feature by detecting only the pixel of the foreground image including the spherical object generated by excluding the motionless background image from each camera image, sorting the interconnected pixels among the pixels of the detected foreground image into the independent pixel cluster, and then, using, in the extraction of the centroid and the feature, only one pixel cluster having a size similar to the actual spherical object.

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.
