Segment Velocity
Segment velocity is an interesting biomechanics parameter, particularly for sports applications. In this tutorial, we focus on what segment velocity actually is, the different ways we can report it, and the meaning of the associated data.
Compute Model Based Data: Target Path
Although we typically use Visual3D for segment-based data, tracking the motion of a specific target has proven to be a very interesting feature for the field of Biomechanics. Using motion capture systems to obtain the 3D coordinates of a marker is essentially what they are designed to do. However, using Compute Model Based Data we can also track the path of a target with respect to any coordinate system defined in our model, including body segments.
Target Path
Tracking specific positions of a target, can be a very useful skill in biomechanics. In this tutorial, we explain why track the position of an individual marker or landmark and why it may be interesting with respect to a segment rather than to the global coordinate system.
Compute Model Based Data: Segment Center of Gravity, Proximal Joint, and Distal Joint
One of the key features of Visual3D is the ability to track landmarks accurately. However, as you build your pipelines, you may be interested in knowing the relative position of a point on a segment. In this tutorial, we show you how to use Compute Model Based Data to obtain the coordinates of the center of gravity, proximal joint, and distal joint of a segment. We also show you how to do this with respect to another segment, and show you some tricks by creating virtual segments in your biomechanical model.
