METHOD OF RECOGNIZING CONTACTLESS USER INTERFACE MOTION AND SYSTEM THERE-OF

摘要

Disclosed are a method of recognizing a contactless user interface motion and an apparatus for the same. The apparatus for recognizing the contactless user interface motion according to the present invention includes a 3-D stereoscopic camera including first and second image sensors and photographing an object; a disparity calculator for creating a disparity map based on a first image taken by the first image sensor and a second image taken by the second image sensor; a position and brightness calculator for calculating the position of the object and the brightness information of the object from the disparity map; a depth calculator for calculating the depth information of the object based on the brightness information of the object and for calculating 3-D coordinates of the object by using the distance information and the position of the object; a speed calculator for calculating a speed from the 3-D coordinates of the object; and a pattern detector for detecting a user interface (UI) pattern of the object based on the 3-D coordinates and speed.
