Paper Abstract

Recent deployments of digital cameras and fast PCs have led real-time interactive systems to adopt vision-based interfaces. However, 2D vision-based interfaces, due to the lack of 3D information, have inherent weakness in tracking 3D objects in real world. In this paper, we propose a vision-based 3D interface for interactive systems that allows an object tracking on the fly in 3D by exploiting multi-view images. Due to the characteristics of interactive systems, requiring real time processing, the main challenge is a simple and robust estimation of 3D information from the images captured by asynchronous digital cameras. The proposed vision-based 3D tracking consists of three steps: (i) dynamic stereo calibration (ii) simple object segmentation (iii) robust 3D movement tracking. To show its effectiveness of the proposed framework, we applied the proposed 3D interface to an interactive 3D Gumdo simulation. Due to the simplicity and robustness of the proposed framework, it can be applied to various real-time interactive applications.
