【摘要】：人体动作损伤评估是产品设计的一个重要范畴,同时也是进行友好的人机交互的重要前提,具有极其重要的意义和宽广的发展前景。原始的人体动作损伤评估需要耗费大量的人力,需要专业人士对所评估对象进行长时间的资料收集和处理。随着计算机技术的飞速发展,虚拟仿真技术也应用到了人机工程学之中。但是通过建模构建虚拟场景及人体模型同样需要花费大量的时间精力,并且设备昂贵,不能够广泛普及。Kinect是微软公司推出的一款体感摄像头,它能够测取人体的场景深度,能够提供人体25个关节点的三维空间坐标。本文在此基础上进行了静态动作下人体动作损伤评估方法的研究。本文选用了常见的两种人体动作损伤评估方法:快速上肢评估(RULA)和OVAKO工作分析系统(OWAS),描述了其评估流程、评估标准及其在实际中的具体应用,并分析了现有人体动作损伤评估存在的弊端。Kinect获取的关节点数据经过处理用以构建人体骨骼向量,通过对骨骼向量及关节角度的划分,参照上述两种评估方法的评分标准,明确在人体动作损伤评估过程中的每一步涉及到的骨骼向量和关节角度,对这两种人体动作损伤评估方法进行了改进。这样做还有利于在程序语言逻辑下进行人体动作损伤评估的编程,为基于Kinect的人体动作损伤评估系统的构建奠定了基础。通过构建基于Kinect的人体动作损伤评估平台,提出了一种简便易行、成本低廉的方法,这种方法在早期设计阶段就能进行人体动作损伤评估,在此基础上设计应用于人体动作损伤评估的原型系统,并对其功能进行了描述。实验结果表明本文所涉及的人机工程学实验及评估系统的有效性及实用性,取得了理想的效果,适合在企业中普及应用。
[Abstract]:Human motion damage assessment is an important category of product design, but also an important prerequisite for friendly human-computer interaction. Has extremely important significance and broad development prospects. The original human body motion damage assessment needs a lot of manpower, It takes professionals to collect and process data for a long time. With the rapid development of computer technology, Virtual simulation technology is also applied to ergonomics. But building virtual scenes and human models through modeling also takes a lot of time and effort, and the equipment is expensive. Kinect is not widely popularized. Kinect is a kind of somatosensory camera introduced by Microsoft, which can measure the depth of human scene. On the basis of this, this paper studies the method of human motion damage assessment under static action. In this paper, two common methods of human motion damage assessment are selected: fast. The Rapid Upper limb Assessment (RULAA) and the OVAKO work Analysis system (OWASA) describe the evaluation process. The evaluation standard and its application in practice, and analyzes the shortcomings of the existing human motion damage assessment. Kinect acquired the key data to construct the human skeleton vector, through the bone vector and joint angle division, Referring to the scoring criteria of the two methods mentioned above, the skeletal vectors and joint angles involved in each step of the assessment of human motion injury are determined. The two methods of human motion damage assessment are improved, which is also helpful to the programming of human motion damage assessment under the logic of program language. It lays a foundation for the construction of human motion damage assessment system based on Kinect. By constructing a human motion damage assessment platform based on Kinect, a simple and inexpensive method is proposed. This method can be used to evaluate human motion damage in the early stage of design. Based on this, a prototype system applied to human motion damage assessment is designed. The experimental results show the effectiveness and practicability of the ergonomics experiment and evaluation system in this paper.
