Abstract:
A position tracking apparatus includes: a depth image obtaining unit for obtaining a depth image; a database created by collecting depth images received from the depth image obtaining unit; a feature extracting unit for extracting features from each pixel of the depth image; a classifier training unit for training a classifier in order to determine the position of the parts of the body by receiving a feature set for each part of the body as inputs which are extracted by using the feature extracting unit from all of the depth images in the database; and a position determination unit for extracting features for each pixel of the depth image received by the depth image obtaining unit using the feature extracting unit in a state in which the classifier training unit trains the classifier, and for tracking the three-dimensional position of each part of the body through the classifier.
