Robust hand tracking method by synchronized high-speed cameras with orthogonal geometry

In this paper, we suggest an intuitive hand motion tracking method using synchronized high-speed cameras with orthogonal geometry. Three synchronized high-speed cameras that capture and process images at the speed of 1,000 frames-persecond concurrently are intentionally arranged so that any pair of optical axes of the cameras cross each other orthogonally. The combination of the high speed with the orthogonal arrangement contributes to robust tracking during dynamic motion with the high-speed three-dimensional reconstruction under occlusion. We present a preliminary hand tracking system using three cameras adopting a minimalist design and also study its feasibility and effectiveness both mathematically and experimentally.
