I-Corps: Assessment of the feasibility of commercialization of a 3D markerless motion capture system with application to physical therapy

低成本和精确的运动捕捉系统是一项技术的根本改进，可用于医生，物理治疗师和其他医疗专业人员诊断，治疗和监测下肢运动障碍患者。目前，运动分析系统耗资数万美元；需要专门的空间和特殊的操作培训。因此，每次进行动作分析的费用高达1000美元，而且只在大型医院才有。低成本深度相机的可用性带来了以当前成本的一小部分执行运动分析的可能性。在这项提案中，该团队开发了一种临床可行的3D无标记运动捕捉系统，满足了医学界对高精度、便利性和可负担性的迫切需求。该团队建议使用市售的深度和彩色摄像机来准确地定义受伤人群的运动机制。该团队开发了一种有效的人体姿势跟踪系统，与基于标记的系统相比，该系统具有相对的准确性。此外，该团队还开发了一种新颖的算法，用于在一般场景中跟踪复杂的人体姿势，从而获得最先进的结果。所提出的系统将建立在现有的新算法的基础上，以实现更高的精度和鲁棒性，为临床中常用的相对更好的控制运动。

A low cost and accurate motion capture system is a fundamental improvement in the technology that is available to physician, physical therapists, and other medical professionals to diagnosis, treat, and monitor patients with movement disorders in the lower-extremity. Currently motion analysis systems cost tens of thousands dollars; require dedicated space and special training for operations. Therefore the cost to perform motion analysis is up to one thousand dollars per session and only available in large hospitals. The availability of low-cost depth cameras brings the possibility to perform motion analysis with a fraction of the current cost. In this proposal, the team has developed a clinically viable 3D markerless motion capture system that meets the strident needs of the medical community for a high accuracy and precision as well as convenience and affordability.The team proposes to use a commercially available depth and color camera to accurately and precisely define movement mechanics of injured populations. The team has developed an effective system for human pose tracking that achieves comparative accuracy to marker-based systems. Moreover, the team has developed novel algorithms for complex human pose tracking in general scenes that achieves state-of-the-art results. The proposed system will build upon the current pipeline of novel algorithms to achieve higher accuracy and robustness for the relatively better controlled motions commonly used in clinics.
