Multi-dimensional Game Interface with Stereo Vision

摘要

An novel stereo vision tracking method is proposed to implement an interactive Human Computer Interface(HCI). Firstly, a feature detection method is introduced to accurately obtain the location and orientation of the feature in an efficient way. Secondly, a searching method is carried out, which uses probability in the time, frequency or color space to optimize the searching strategy. Then the 3D information is retrieved by the calibration and triangulation process. Up to 5 degrees of freedom(DOFs) can be achieved from a single feature, compared with the other methods, including the coordinates in 3D space and the orientation information. Experiments show that the method is efficient and robust for the real time game interface.
