XSens - OpenSim modelling

This project intends to assess the feasibility of using inertia-tracking system (i.e. XSens) to provide input data for modelling in OpenSim. We adapted the Catelli model to the 'T-pose' used for XSens to scale their biomechanical model. We also created the virtual markers exported at the C3D files from MVN Analyse into OpenSim .xml files. In addition, we developed scripts in order to convert data from XSens in the TRC files required for scaling, based on work from Felipe Alvim and others.In order to convert the data from XSens to OpenSim, the following steps are required:1- Export the data from MVN Studio as C3D assigning the first frame as the 'T-pose';2- Use the codes provided in this project to convert the C3D files into TRC (static and motion)This project also allows you to export data from Kistler Bioware software to .mot files, if you wish to do Inverse Dynamics. For this step, you have to export the data as .txt files and use these files into the program block associated with the Bioware convertion. <br/><br/>This project includes the following software/data packages: <br/> <ul> <li> <a href="https://simtk.org/frs?group_id=1417#pack_1978">XSens_model_scripts </a> : This package is based on work from other projects:1- https://simtk.org/projects/c3d2opensim2- https://simtk.org/projects/c3dtoolboxYou need btk package to use the scripts provided </li> </ul>

本项研究旨在评估使用惯性跟踪系统（即XSens）为OpenSim建模提供输入数据的可行性。我们针对XSens所采用的'T-pose'姿势对Catelli模型进行了适配，以对其进行生物力学模型的缩放。此外，我们还创建了虚拟标记，将这些从MVN Analyse导出的C3D文件转换为OpenSim的.xml文件。同时，基于Felipe Alvim等人的研究成果，我们开发了脚本，以便将XSens的数据从TRC文件中进行转换，以满足缩放需求。为了将XSens的数据转换为OpenSim，需遵循以下步骤：1- 将MVN Studio中的数据导出为C3D格式，并将第一帧指定为'T-pose'；2- 使用本项目提供的代码将C3D文件转换为TRC（静态和动态）格式。此外，本项目还允许用户将Kistler Bioware软件的数据导出为.mot文件，以便进行逆动力学分析。为此步骤，您需将数据导出为.txt文件，并使用这些文件在Bioware转换相关的程序块中。
