Capture and reconstruct the marker set

After you have prepared your subject (see Create a subject node and prepare a subject), you can capture the marker set. To do this, you capture a brief static trial, ensuring that the subject is positioned in the required base pose (for details of how to produce a reliable base pose, see below), with all the markers visible to the cameras.

To capture a trial containing the markers:

1. With the subject in the middle of your capture volume, ensure you can see the subject's unlabeled markers in the 3D Perspective view.
2. Position the subject in the required base pose. Ensure that the pose meets the following criteria:
   
   • Easy for the subject to achieve and to reproduce
   • All the markers are clearly visible to all cameras. For example, if the subject requires assistance or a mobility aid to achieve the base pose, ensure that these do not hide any markers from the cameras. Also avoid positioning limbs in such a way as to hide markers (for example, arms folded or legs crossed).
3. Perform a short (a few seconds) static capture. To do this:

   1. With Nexus in Live mode, in the Subject Preparation pane , click Start in the Subject Capture section. The Start button label changes to Stop.

   2. Click Stop to finish the capture.

4. To reconstruct the markers, on the tool bar click the Reconstruct button , or run the Reconstruct pipeline.

5. In the 3D Perspective view, check that all the markers attached to your subject have been reconstructed.

You can now add any required parameters to the template.
