摘要:: 系统以惯性传感器的数据采集为硬件基础,借助 ARDUINO 开发平台,在 Unity3D 软件中实现了虚拟仿生模型的动作设计。基于仿生模型的三维姿态解算原理,设计并渲染了虚拟的手臂仿生模型,依此剖析模型的姿态变化方式;根据手臂模型的 3D 脚本控制,实现模型节点角度的三维空间变化;在惯性传感器的应用基础上,完成固定于测试者手臂上的三个传感节点的数据采集,并通过 ARDUINO 开发平台将角度数据传至上位机。在上位机 3D 视频软件中,通过挂接模型的脚本文档,将硬件获取的角度数据与虚拟手臂模型的 3 个节点的 transform 组件相关联,实现虚拟仿生动作与测试者实际动作的同步变化,同时达到了虚拟模型的动作捕捉设计的基本要求。

Abstract:: Based on the data acquisition of inertial sensors,with ARDUINO development platform,we have realized the action design of virtual bionic model in the Unity 3D software. Adopting the principle of three - dimensional attitude calculation of bionic model,we design and render a virtual arm bionic model,and then analyze the posture change mode of the model. According to the 3D script control of the arm model,three-dimensional spatial change of the node angle of the model is realized. On the basis of the application of inertial sensors,the data collection of three sensor nodes which are fixed on the arm of the tester has been completed,and the angle data is transmitted to the upper computer through the ARDUINO development platform. In the host computer 3D video software,the angle data obtained by the hardware is associated with the transform component of 3 nodes of the virtual arm model by hanging the script document of the model. It realizes the synchronous change of virtual bionic action and the actual action of the tester,and at the same time,achieves the basic requirements of the motion capture design of the virtual model.
