Established methods for postural ergonomic risk assessment in occupational practice are mostly time-consuming and need to be conducted by experts. Use of technology could improve postural ergonomic risk assessments with regard to time efficiency and accuracy. A study was conducted to assess the accuracy of a markerless motion capture system (Microsoft Kinect V2) compared to a marker-based motion capture system (Vicon Bonita). Angles of different body segments were analysed. The results show major inaccuracies of the markerless motion capture system for capturing axial trunk rotation (mean angular deviation of 14.04°) indicating that potential health risks could be underestimated. Combined working postures of axial trunk rotation and arm anteversion show issues with self-occlusion. Based on the findings, it is discussed whether the detected inaccuracies for axial trunk rotation are likely to lead to overestimation or underestimation of potential health risks when conducting an ergonomic risk assessment.

用于职业实践中姿势人体工程学风险评估的无标记运动捕捉系统的准确性

职业实践中体位人体工程学风险评估的既定方法大多耗时,需要由专家进行。技术的使用可以改善关于时间效率和准确性的姿势人体工程学风险评估。进行了一项研究,以评估无标记动作捕捉系统 (Microsoft Kinect V2) 与基于标记的动作捕捉系统 (Vicon Bonita) 的准确性。分析了不同身体部分的角度。结果表明,无标记运动捕捉系统在捕捉躯干轴向旋转(平均角度偏差为 14.04°)方面存在重大不准确,表明潜在的健康风险可能被低估。轴向躯干旋转和手臂前倾的组合工作姿势显示出自闭锁问题。根据调查结果,
