增强现实（AR）最近已经成为一个全球性的研究课题。AR技术在用户的物理环境中呈现直观的计算机生成的内容。为了提高过程效率和生产力，研究人员和开发人员越来越关注AR在工程分析和仿真中的应用。AR与有限元等数值模拟的结合，为用户分析实际问题提供了一种认知的、科学的方法。通过结合科学可视化技术，基于AR的系统将工程分析和仿真结果直接叠加在现实世界的对象上。涉及不同类型数据的工程分析和模拟通常使用特定的计算机软件进行处理。使用AR平台对这些数据进行正确有效的可视化可以减少空间和逻辑方面的误解。此外，AR平台在工程分析和仿真中的跟踪性能至关重要，因为它会影响整体用户体验。AR平台的操作环境需要强大的跟踪性能，以向用户提供稳定和准确的信息。此外，在过去的几十年里，AR经历了从桌面到移动的计算的转变。移动的平台的便携性和传播为工程师提供了方便的现场访问相关信息。然而，现场的工作环境对基于移动的AR系统的发展施加了限制。本文旨在提供一个系统的概述AR在工程分析和仿真。讨论了可视化、跟踪技术及其在移动的平台上的实现。每种技术都分析了其优点和缺点，以及对特定类型应用程序的适用性。
Augmented reality (AR) has recently become a worldwide research topic. AR technology renders intuitive computer-generated contents on users’ physical surroundings. To improve process efficiency and productivity, researchers and developers have paid increasing attention to AR applications in engineering analysis and simulation. The integration of AR with numerical simulation, such as the finite element method, provides a cognitive and scientific way for users to analyze practical problems. By incorporating scientific visualization technologies, an AR-based system superimposes engineering analysis and simulation results directly on real-world objects. Engineering analysis and simulation involving diverse types of data are normally processed using specific computer software. Correct and effective visualization of these data using an AR platform can reduce the misinterpretation in spatial and logical aspects. Moreover, tracking performance of the AR platforms in engineering analysis and simulation is crucial as it influences the overall user experience. The operating environment of the AR platforms requires robust tracking performance to deliver stable and accurate information to the users. In addition, over the past several decades, AR has undergone a transition from desktop to mobile computing. The portability and propagation of mobile platforms has provided engineers with convenient access to relevant information in situ. However, on-site working environment imposes constraints on the development of mobile AR-based systems. This paper aims to provide a systematic overview of AR in engineering analysis and simulation. The visualization, tracking techniques as well as the implementation on mobile platforms are discussed. Each technique is analyzed with respect to its pros and cons, as well its suitability to particular types of applications.
