Abstract
This paper proposes a human body posture estimation method based on back projection of human silhouette images extracted from multi-camera images. To achieve real-time 3D human body posture estimation, a server-client system is introduced into the multi-camera system, improvements of the background subtraction and back projection are investigated. To evaluate the feasibility of the proposed method, 3D estimation experiments of human body posture are carried out. The experimental system with six CCD cameras is composed and the experimental results confirm both the feasibility and effectiveness of the proposed system in the 3D human body posture estimation in real-time. By using the 3D reconstruction of human body posture, the simple walk-through application of virtual reality system is demonstrated.
