摘　　要：由于MEMS惯性传感器在人体动作数据采集时会受到重力加速度的影响,导致人体动作捕捉效果差,提出基于改进MEMS惯性传感器的人体动作智能捕捉方法。运用MEMS惯性传感器获取人体动作数据,并对采集的数据实施数据去噪、误差校正、重力加速度去除等处理,优化MEMS惯性传感器的数据采集效果,获取实际的人体运动数据。依据获取的人体运动数据,将方差作为人体整体运动幅度的特征向量值,提取人体动作特征,结合支持向量机对动作进行分类识别,实现人体动作捕捉。实验结果表明,使用上述方法开展人体动作捕捉时,捕捉精准度较高、捕捉时间较短,且实际效果较好。Due to the influence of gravity acceleration on the collection of human motion data using MEMS inertial sensors,the effectiveness of human motion capture is poor.Therefore,an intelligent human motion capture method based on improved MEMS inertial sensors was proposed.Firstly,MEMS inertial sensor was used to obtain human motion data.For the collected data,data denoising,error correction and gravity acceleration removal were carried out.And then,the data collection effect of MEMS inertial sensor was optimized to obtain actual human motion data.According to the data,the variance was taken as the feature vector value of the motion amplitude of human body.Finally,the features human action was extracted.Meanwhile,the action was classified and recognized with the support vector machine.Thus,the human motion capture was achieved.Experimental results show that the capture accuracy is higher,and the capture time is shorter.In addition,the actual effect is better during the human motion capture.
