增强现实技术在虚拟实训系统中应用实践

The Application and Practice of Augmented Reality Technology in Virtual Training System

针对目前虚拟实训系统使用中存在的各种问题,提出一种基于增强现实技术的虚拟实训系统解决方案.提出创设情景和基于图像识别的算法,快速找到应用应情景与实训实验之间的关系;其次,应用渲染算法和光照模型,快速生动加载虚拟设备;最后,提出基于增强现实技术的互动模式算法,加强实训实验的体验和操作.实验结果表明,增强现实技术的运用使得虚拟实训系统操作更简单、方便,学习效率有较大提高.

In view of the problems in virtual training system, a solution based on Augmented Reality was proposed. After creation of scenarios in virtual training system, firstly, an image and object recognition algorithm which can provide a route between the image and experiment was proposed. Secondly, author made the virtual equipment to load vividly and quickly, through rendering algorithm and illumination model algorithm. Finally, an interactive mode algorithm based on augmented reality technology was applied to in order to strengthen training and operations. Experimental results show that the use of augmented reality technology makes virtual training system easier, more convenient, learning efficiency has improved greatly.
