Estimation of Face Posture and Hands Motion of Car Driver by Particle Filters in Real-time

パーティクルフィルタによる運転者の顔姿勢および両手挙動の実時間推定

As a future safety driving support based on a car driver's behavior grasped by non-contact sensors, general state space modeling and sequential state estimation by particle filter have been used to estimate the car driver's behavior accurately and being in real-time. Face posture to observe outside of the car and both hands motion to operate steering have been employed as the car driver's behavior. Face camera set over the steering and steering camera set above the seat-belt roller are used to capture video images. Robust methods for sudden motion of face direction and mutual occlusion of hands have been proposed.非接触型センサによる運転者挙動の把握に基づく,将来の安全運転支援の一つとして,一般状態空間モデリングとパーティクルフィルタによる逐次状態推定を使って,運転者挙動を正確かつ実時間で推定する.車両の外界を観察する顔姿勢と,ステアリングを操作する両手の動きを,運転者の挙動とする.顔カメラをステアリング前方に設置し,ステアリング用カメラをシートベルト巻取り上部に設置し,動画像を撮影する.顔向きの急な変化や,両手相互の隠れに対し,頑健な方法を提案する.
