基于约束的手形分析

Hand-Shape Analysis Based on Restriction

随着虚拟现实技术的发展,出现了众多与虚拟现实进行交互的方法,其中使用手势语言来进行人机交互逐渐成为研究的热点。在总结手运动约束关系的基础上,通过7个关键点,推算出手的空间姿态,可以在虚拟环境中再现手的姿态。算法提高了运算速度,保证了实时性,使用摄像机采集原始图像克服了数据手套获取手形时的不灵活等缺点,在虚拟现实环境的交互中得到了较好的应用。

With the development of virtual reality technologies, plenty of methods of man-machine interaction have came out, and among them, hand gestures analysis is becoming one of the hottest spots in the domain. Based on the constraints of kinematics of hand movements, an algorithm to calculate the hand shape with seven characteristic points is proposed, and then the gesture in the virtual scene can be reshaped. This algorithm accelerates the progress of computing in order to support real-time rendering, and avoides the low-agility problem of data glove by using cameras for image-acquisition. Therefore it can well adapt to interact in virtual scenes.
