Motion capture refers to the process of recording movement of one or more persons or objects. It serves as an essential technology to many industries, including entertainment (gaming and filmmaking), movement science (human factors and kinetics), virtual reality (training and simulations), and health (diagnostics and monitoring). In gaming and filmmaking, it is used to record actions of human actors or athletes, and using that information to animate digital character models in 3D computer animation. The main goal of this Strategic Project Grants (SPG) proposal is to develop an innovative wireless, real-time 3D motion tracking system for true ambulatory applications in gaming and filmmaking. A key technological element in this endeavor is the advent of the state-of-the-art MEMS-based tri-axial inertial sensors that can be integrated with emerging short-range wireless technologies to implement a ubiquitous intra- and multi-subject motion tracking system that is capable of on-field measurements. In comparison to traditional motion capture (MoCap) systems such as the 'gold-standard' optical systems, the proposed wireless inertial MoCap ("wiMoCap") system has the potential to be truly 'ambulatory' and unlimited in range, as long as the system's positional accuracy and battery life allows. Therefore, the development of a low-power and drift-free wiMoCap system using novel sensor fusion algorithms, low-power wireless sensor networks (WSN) and distributed data compression is the main focus of this project proposal. Inertial sensor-based motion capture is an emerging and fastest growing MoCap technology. The proposed multidisciplinary project is a collaborative venture between Drs. Park (PI), Lee and Bajic of the Simon Fraser University (SFU) and Electronic Arts ("EA"), one of the largest video game publishers/developers in the world. EA Canada, EA Capture (Burnaby, BC) in particular, will make significant in-kind contributions to the project as the development of the proposed wiMoCap technology is intimately in-line with its business and R&D interests. The proposed technology offers various technical MoCap innovations that can revolutionize the gaming and filming industries within the next five years.

运动捕捉是指记录一个或多个人或物体的运动的过程。它是许多行业的基本技术，包括娱乐（游戏和电影制作），运动科学（人为因素和动力学），虚拟现实（培训和模拟）和健康（诊断和监测）。在游戏和电影制作中，它用于记录人类演员或运动员的动作，并使用该信息在3D计算机动画中对数字角色模型进行动画制作。该战略项目赠款（SPG）提案的主要目标是开发一种创新的无线实时3D运动跟踪系统，用于游戏和电影制作中的真正移动应用。这一奋进中的一个关键技术要素是最先进的基于MEMS的三轴惯性传感器的出现，该传感器可以与新兴的短距离无线技术集成，以实现能够进行现场测量的无处不在的受试者内和多受试者运动跟踪系统。与传统的运动捕捉（MoCap）系统（诸如“黄金标准”光学系统）相比，所提出的无线惯性MoCap（“wiMoCap”）系统具有真正“移动”并且范围不受限制的潜力，只要系统的位置精度和电池寿命允许。因此，开发一个低功耗和无漂移的wiMoCap系统，使用新的传感器融合算法，低功耗无线传感器网络（WSN）和分布式数据压缩是本项目建议的主要重点。基于惯性传感器的运动捕捉是一种新兴的、发展最快的运动捕捉技术。拟议的多学科项目是西蒙弗雷泽大学（SFU）的Park（PI），Lee和Bajic博士与世界上最大的视频游戏发行商/开发商之一Electronic Arts（“EA”）之间的合作项目。EA加拿大，EA捕获（伯纳比，不列颠哥伦比亚省），特别是将作出重大的实物捐助的项目，因为拟议的wiMoCap技术的发展是密切符合其业务和研发利益。这项技术提供了各种技术MoCap创新，可以在未来五年内彻底改变游戏和电影行业。
