为了达到视域评估的可视化效果,文中构建了人眼可视范围的半透明模型,并绑定到虚拟人的骨骼中,通过驱动虚拟人,以实时混合绘制技术完成动态视域评估。以龙门式数控加工中心造型设计模型为对象进行实例仿真,结果表明逼真的可视化效果使得视域评估变得简单、快捷和直观,避免了大量的人工运算,提高了视域评估的速度、降低了人为失误。该方法可直接面向工程的实际应用,满足各类布局设计的可视化评估要求。

Visual range assessment is an important part of the ergonomics analysis.In order to get achieve visual effects for the visual range assessment,we construct a translucent model of the human eyes' visible range and bind it to the bones of the ergonomic virtual human.Then,a real-time dynamic visual range evaluation is achieved by using real-time blend rendering technology.As an example,the gantry CNC machining center design model is taken to demonstrate the effectiveness of the method.It shows that the vivid visualization analysis not only makes the ergonomics analysis simple,fast, and visible,but also avoids many manual operations,improving the speed of the analysis,and reducing the human errors.The method can be applied in the practical engineering directly and it can support the visibility analysis of various types of layout design.
