After you have configured your system (see Prepare a Vicon system), the next step is to calibrate the Vicon cameras and define the origin of the capture volume. Calibration enables Nexus to determine the positions, orientations, and lens properties of the Vicon cameras and to produce accurate 3D data.
Vicon recommends that you calibrate your Vicon cameras after any changes to your system and each day, before you capture any data. This ensures that any accidental changes in your setup (such as a camera being knocked while the system was unsupervised) does not influence the quality of your data. You can perform the level of camera calibration that suits your requirements: a full camera calibration or a calibration refinement.
The following topics cover calibrating the Vicon system for motion capture:

As the videos were recorded using an earlier version of Nexus 2, you may notice small differences in the user interface.
