摘 要

增强现实技术源于虚拟现实，是在其基础上发展起来的。增强现实技术的主要目的是通过在现实世界中叠加虚拟信息从而实现对现实世界的增强。由于增强现实的真实性、实用性和交互性，可以让用户能以更加自然的方式在现实世界中与计算机渲染虚拟出来的物品进行交互。基于这样的显著优势，国内外已经有很多的尝试将增强现实技术应用于肌电假肢训练平台开发之中，以此来提高患者的参与积极性，降低人力成本并且能够提供可靠稳定有趣的训练模式和肌电假肢训练的评测指标。因此，本文设计了一个基于增强现实技术的肌电假肢训练平台。

首先，本文分析了增强现实应用于肌电假肢训练平台开发的背景和重要意义，通过国内外的研究现状，提出利用增强现实技术的必要性。其次，本文对增强现实核心技术进行了分析并将其与虚拟现实进行对比，得出其优势之处。此外，本文对平台所需要的硬件设备进行了选型和相关的配置，其中主要包括了摄像头的校准、MYO臂环的使用以及跟踪定位用标识的设计和制作。另外，本文提出了利用ARToolKit、OpenGL以及MYO SDK等软件开发包对肌电假肢训练平台进行编程开发设计，同时还具体阐述了每个工具包的使用要点以及调用规则和编程设计具体流程。

最后，本文对整个系统进行了总结并针对于不足之处给出了未来的改进方案。

ABSTRACT

Augmented reality came from the virtual reality technology and developed on the basis of virtual reality. The main purpose of the augmented reality technology is to enhance the real word by superimposing the virtual information into the real world. Because of authenticity, usability and interactivity of the augmented reality, it allows the users to interact with virtual objects through a more natural way in the real world. Based on these significant advantages, there are a lot of domestic and overseas attempts to apply the augmented reality technology in development of myoelectric prosthesis training platform, in order to improve the enthusiasm of patients who participate in the therapy, reduce labor cost and can also provide stable, reliable and interesting training modes and indicators to evaluate the training effect. Therefore, this paper designs a myoelectric prosthesis training platform based on the augmented reality technology.

First of all, this paper analyzes the background and significance of the augmented reality technology applied in myoelectric prosthesis training platform, and put forward the necessity of using augmented reality through domestic and overseas research status. Secondly, this paper analyzes the core technology of augmented reality and compares it with the virtual reality technology to put forward its advantages. Thirdly, this paper conduct the equipment selection and related configuration of the hardware the platform requires, which includes the camera calibration, use of MYO band and design and production of the pattern used to track and locate. In addition, this paper puts forward the development and design of the myoelectric prosthesis training platform by using software development kit such as ARToolKit, OpenGL, and MYO SDK. At the same time, it also elaborates the operation keys, calling rules and concrete process of programming.

In the end, this paper summarizes the whole system and gives the future improvement scheme for its shortcomings.
