VR外设驱动的虚拟人姿态优化仿真方法

为解决常用的VR外设为穿戴于操作者身上的位置跟踪器，会给操作者带来额外不便的问题，提出一种基于视觉传感器组合的虚拟人驱动方案，实现简便无标记虚拟人运动实时驱动。引入参数化人体模型SMPL(skinned multi-person linear)，通过最小化多个误差项组成的目标函数，改进算法提高虚拟人驱动精度，并计算得到符合真人形态与姿态的拟合人体模型数据，实现操作姿态人机工程学评价。实验结果表明：所提出的虚拟人数据驱动方法具有有效性。

Simulation Method of Virtual Human Pose Optimization Based On VR Peripherals

The commonly used VR peripheral is the position tracker worn on the operator body and is not very convenient. Focus on the problem, a visual sensor combination-based scheme is proposed to realize the simple and real-time unmarked virtual human driven simulation. On the basis of the parameterized human model SMPL, by minimizing the objective function of multiple error terms, the driven accuracy of the virtual human is improved, and the fitted human body model conforming to the operator form and posture is calculated and the ergonomic evaluation is realized. The module is verified by a case of evaluation in a ship cabin. The result shows that the proposed method is available.
