3.2 The fusionTrack device
Here below is a simple description of its operation:
1. The fusionTrack illuminators emit infrared (IR) light, like the flash of a regular camera;
2. The IR light reflects on passive
markers
or triggers active
markers
which then emit IR light;
3. The fusionTrack detects the reflected (or emitted) IR light and transmits the information to the host
computer along with status information;
4. The host computer extracts the position of each detected spot, computes the 3D position of each
detected sources, then tries to match them to known
marker
geometries;
5. The information is forwarded to the user, with status information on each piece of data, allowing the
user to do additional processing (display, filtering, collection, etc.).
The fusionTrack device can track two types of
markers
: passive and active ones. More detailed explanations
about those two
marker
types are given in Section 7.6.
The fusionTrack device must be powered off when not in use
(e.g. using a switch before the
PoE
+
PSE
). The powered-
on time, be the fusionTrack device used or not, is cut away
from the service life.
On Figure 3.2 is presented the front view of the fusionTrack. It should be noted that ‘Left’ and ‘Right’ always
refer to the vision from the fusionTrack.
