ABSTRACT:
A marker-free motion capture apparatus having a function of correcting a tracking error and a method thereof are disclosed. The apparatus includes: a grouping unit for grouping feature candidates located within a threshold distance on a three-dimensional space at a previous time; a feature point selecting unit for generating a first curve connecting a predetermined number of feature points, and selecting a feature candidate closest to the first curve as a feature point of a previous time; a feature point correcting unit for generating a second curve connecting a predetermined number of feature points including the feature point of a previous time, and correcting a feature point of a current time calculated based on a Kalman filtering scheme using the second curve; and a controlling unit for calculating a location of a feature point of each time using a Kalman filtering scheme and generally controlling the marker-free motion capture apparatus.
