This picture show the “Arena” software program interface for capturing the “dots” motion.
It provides the position and orientation data about dots especially rigid body.
This tutorial will explain about how to get position and velocity data.
Motivation and Audience
This is a tutorial about getting position & velocity data from Optitrack Motion Capture system. If you are not familiar to use “Arena” which is Optitrack Motion Capture system software, Please take look at up the “Optitrack Motion Capture System Setup Guide” http://daslhub.org/unlv/wiki/doku.php?id=optitrack_motion_capture_system_setup_guide
Once you know how to record the “dots” movement, you can get the position data through “Arena” software program. But, you need to use other tool(e.g. matlab or excel) for calculating velocity.
* Experience about “Arena” software.
* Know how to get velocity data from position data.
The rest of this tutorial is presented as follows:
Create Rigid Body
For this section, the reader will first need to confirm that they have all the parts listed in the bellow. Please find the desktop computer labeled “Motion PC” for the Arena Motion Capture Software. Reference the links to find out what each part should look like.
