Abstract: In our augmented reality system,the throwing is taken as a main interactive method.So the system must have the abi-lity of action recognition and quick response.The character of throwing is analyzed firstly,and the changing law of its velocity is emphasized.Based on them,a new algorithm is designed with the knowledge of moving-average and fuzzy synthetic judgment.This algorithm can recognize the throwing,and calculate the initial velocity of the virtual object.The experiments demonstrate the system needn’t limit the throwing type and velocity,and has a good real-time ability.

Key words: action recognition, average-moving, fuzzy synthetic judgment, throwing, augmented reality

摘要: 在增强现实系统中,以抛掷作为主要交互手段,必须要具备高效的动作识别和响应能力。从抛掷动作的特征入手,着重分析了它的速度变化规律。依据此规律,设计了滑动平均结合模糊综合评判的算法,实现了对抛掷动作的准确判断,和虚拟物体的起抛速度的精确计算。实验结果表明,系统不受抛掷速度和种类的限制,有很好的实时性。
