摘　　要：人类肢体的运动可以简化为像连杆的刚性运动,而运动着的四肢与躯干之间总能形成一个角度关系.利用在人体手臂上固定三轴加速度传感器,通过一定的变换能实时计算出手臂与躯干上固定点的角度信息.基此设计了一种新的改进角度算法,通过实验对结果数据进行分析,并利用软件建立人体模型,在OSG平台上进行仿真,证明了算法的正确性以及在人体姿态跟踪中应用的可行性.The human body movement can be simplified as rigid motion like connecting rods.While human body moves,there is always an angle between the moving limbs and the trunk.If a three-axis accelerometer is fixed on the arm of the body,the angle between the arm and the trunk can be calculated in realtime.In this paper,an improved angle algorithm is designed.This algorithm analyzed the data of the experiments,established the human body model and made a simulation experiment on OSG platform.It is proved that the algorithm is correct and can be applied to track body posture.
