System & SetUp

All motion capture activity takes place in the capture volume. This is the area view-able by the motion capture cameras.













Motion is tracked by the system by bouncing light off reflective markers placed on the actor who is wearing the required suit. The markers help identify the skeleton on the body.  It is also important when placing the markers correctly on the body if not it may cause some problems. 














But before we bring in the actor we first identify the capture volume using the volume opti wand which defines the cameras capture volume. We then identified the floor using the calibration square which has markers the cameras pick up. The floor is then seen on the grid in the view-port of the software.


When we began to setup the system with the motion capture cameras and hubs we checked for any unwanted reflective surfaces or objects. To minimize distortion, we remove all metallic like objects from the capture area for a better result. The hubs which connect all the cameras had unwanted flickering lights which were being read through the hard ware motive’s camera views. So we covered those lights up. This way no unwanted flickering of light will interfere with the markers placed on the actor. After doing all that we were ready to begin shooting.
