摘要
提出了一种新型虚拟训练软件输入设备,以解决目前虚拟训练软件常用的输入设备逼真度不足的问题;系统将微惯性测量原理应用于人体姿态检测,选用微机电系统(Micro Electro Mechanical Systems,MEMS)器件构建微惯性测量单元(Micro Inertial Measurement Unit,MIMU)作为人体训练动作的硬件采集设备;采用VC++设计上位机系统软件完成人体动作检测与识别,系统软件通过软件接口驱动虚拟训练软件;通过原理样机测试,系统运行稳定可靠,解算精度在3°以内,该研究拓展了MEMS器件的应用领域,极大增强了虚拟训练的真实感和训练效果。
This research was conducted to design a Human Interface Device （HID） for the virtual training software to improve the effect of virtual training. With the principle of Strap--down Inertial Navigation System, designed Micro Inertial Measurement Unit （MIMU） with Micro Electro Mechanical Systems （MEMS） devices as the data acquisition unit to measure the human training motion; Designed system algorithm to acquire human training motion; Programmed the system software with VC＋＋, using software interface to communicate with the virtual training software. After testing of the model machine, the results showed that the resolving precision, which was 3＊at least, satisfied the requirement of the virtual training software. This research widened the application realm of MEMS devices, improved the effect of the virtual training, and then has a wide market future.
