XSENS SOFTWARE DOWNLOAD MAC

You can perform the OpenSense workflow on Mac or Windows through: OpenSense can be downloaded from SimTK, with both Windows and Mac builds available.

XSENS SOFTWARE DOWNLOAD INSTALL

To get started, you will first need to download and install the latest OpenSim version (minimum version is 4.1). The OpenSense workflow is available as of OpenSim 4.1.

Read more about this step in the User's Guide chapter on IMU Inverse Kinematics.īack to top How to Setup the OpenSense Tools The resulting Model and Motion can be loaded, visualized, and analyzed in the OpenSim GUI. As of OpenSim 4.2, the calibration and inverse kinematics steps are also available through the OpenSim GUI. The OpenSense capabilities are available through the command line and through scripting (Matlab or Python). The angles can then be used as inputs to other OpenSim tools and analyses or you can visualize these angles in the OpenSim GUI. Computing Inverse KinematicsĪn inverse kinematics method is used to compute the set of joint angles at each time step of a motion that minimizes the errors between the experimental IMU orientations and the model’s IMU Frames. Read more about these steps in our User's Guide chapter on the IMU Placer tool. to optimize the initial pose of the model for calibration using other data sources (markers, goniometer, etc). You can also write your own calibration procedures in Matlab, Python, etc.

You change the registration pose by changing the default coordinate values of the model. We provide a basic calibration routine in which the first time step of IMU data is registered to the default pose of the model. OpenSense provides an interface to associate and register each IMU sensor with a body segment of an OpenSim model (as an IMU Frame). Several open-source sensor fusion algorithms are also available on GitHub. We currently assume that sensor fusion and syncing have been performed using a vendor’s or third-party algorithm. You can create your own file converter to support any other IMU system and we plan to add support for additional sensor manufacturers in the future. We currently support Xsens and APDM file formats. You must also input orientations from one or more IMU sensors. There are many more models available through our Model Library. If you are solely interested in joint angles and other kinematic quantities (e.g., normalized muscle lengths and lengthening velocities), the model need not be scaled to the anthropometry of the subject. In the example below, we provide a model for studying lower-extremity kinematics during gait. To get started, you will need an OpenSim model that includes the joints and degrees of freedom of interest. The OpenSense workflow is summarized in the text and flowchart below.

OpenSense is a workflow that enables users to compute the motions of body segments based on inertial measurement unit (IMU) data, as shown in the animation below.
