虚拟现实电力培训系统场景渲染方法改进与实现

Improvement and Implementation of Scene Rendering Method for Virtual Reality Power Training System

结合虚拟现实技术、三维建模技术、计算机仿真技术的电力培训仿真系统以其高交互性、高沉浸感、低成本、安全高效的优势在电力培训领域得到了广泛的应用。从视觉和行为交互上为学员构建一个接近现实的作业环境是虚拟现实电力培训系统的最根本特征,但是电力作业培训高频率的人机交互操作会导致高质量的作业环境模型产生渲染困难,影响培训效果。为提升系统运行流畅性和实时性,提出了一种改进的四叉树场景渲染方法,利用迭代构造方法改进了传统递归遍历四叉树的过程。实际应用效果表明采用改进的场景渲染方法会使得培训系统渲染流畅,三维效果逼真,增强了系统的实时性和学员的使用体验,提升了培训效果。

The power training simulation system,which combines virtual reality technology,three-dimensional modeling technology and computer simulation technology,has been widely used in the field of power training with its advantages of high interactivity,high immersion,low cost,safety and efficiency.Building a close-to-reality operating environment for trainees from the perspective of visual and behavioral interaction is the most fundamental feature of virtual reality electric power training system.However,the high frequency of human-computer interaction in power job training will lead to high-quality job environment model rendering difficulties and affect the training effect.To improve the smoothness and real-time performance of the system,an improved quadtree scene rendering method is proposed,and the traditional recursive quadtree traversal process is improved by using the iterative construction method.The practical application results show that the improved scene rendering method will make the training system render smoothly and three-dimensional effect lifelike,enhance the real-time performance of the system and the use experience of trainees,and improve the training effect.
