In this thesis, we have explored the use of the latest motion tracking technologies, as evident by Microsoft Xbox Kinect’s motion tracking capabilities, in combination with 3D digital human modeling and animation, multi-modality image capturing and processing, and fusion, to design a new generation of low-cost range of motion and gait analysis solutions that overcome the limitation of existing tools. The proposed solutions and our prototype systems have demonstrated accurate measurements and reliable analysis outcome compared to current clinic practices, with significantly reduced complexity and cost. Furthermore, it eliminates the need for expensive effort for pre- and post- processing of data, and also the need for a large lab space for placing the camera array. As a result, it is particularly suitable for deployment directly at doctor/therapist offices. Without having to send patient to the motion labs, which could be far away and expensive in most places, it gives them a tool to quickly and conveniently capture and access the range of motion and gait result for enhanced diagnosis, treatment, and rehabilitation for joint problems, e.g., for joint replacement and repair patients.Specifically, we have developed a touch-free solution for measuring the joint range of motion in the human body to address the clinic needs of evidence to support accurate diagnosis, treatment and rehabilitation for joint problems, and improvediiiinteraction and among patient, doctor, therapist and etc. In our approach, we will gather motion data captured through the motion tracking device Kinect and real- timely process motion data to obtain range of motion in enhanced accuracy and reproducibility. We have completed a prototype, which illustrates our entire work flow. Our preliminary experiment results have shown our system provides reliable and effective analysis of range of motions.We have also started the design and development of a Kinect-based gait analysis system to provide a broad range of high quality body motion analysis without having to depend on high cost equipment. We have completed all function components of the prototype and have use it to demonstrate the correctness, effectiveness and reliability of such an ultra-low cost solution in practice. Our preliminary experiments for feasibility study have shown consistent reproducibility and accuracy.In Summary, we have developed prototypes for range of motion and gait analysis, and have carried out experimental study to show their capabilities. We believe these new techniques will improve the current practice in clinical body motion analysis. |
