Abstract: An apparatus and method for tracing a motion of an object using high-resolution image data and low-resolution depth data acquired by a hybrid camera in a motion analysis system used for tracking a motion of a human being. The apparatus includes a data collecting part, a data fusion part, a data partitioning part, a correspondence point tracking part, and a joint tracking part. Accordingly, it is possible to precisely track a motion of the object by fusing the high-resolution image data and the low-resolution depth data, which are acquired by the hybrid camera.

Abstract: Provided are a method and apparatus for tuning a trajectory model of a ball. The method includes generating a real trajectory of the ball based on a difference among a plurality of flight images for the ball, calculating kinetic characteristics of the ball based on the real trajectory, correcting at least one of the kinetic characteristics and a characteristic coefficient of the ground based on the real trajectory, and tuning a ball simulation trajectory based on the corrected at least one of the kinetic characteristics and the characteristic coefficient of the ground. A trajectory after the ball collides with the ground can be accurately generated.
