Voyager III Firefighter Mode and Tracking
Acquiring a Target
After you have positioned the region of interest within the acquisition window and
you see the white tracking gate, you double-pump the joystick to engage a target
within the acquisition window. The system automatically determines the size of
the target to track using its internal calculations. However you can fine-tune the
size using puck movements and then reacquire the target at a more precise size.
Consider this scenario. You want to track a boat and the area of the boat where
the engine is located gives the best white-hot contrast. High contrast is one of the
factors that helps the tracker stay engaged. When you first acquire the target, the
tracking gate includes the white-hot area and a substantial region around it. You
can use puck movements to ensure that the white-hot region is exactly in the
center of the tracking gate.
Then to reduce the size of the tracking gate and have a more optimal target,
follow these steps.
After three seconds of tracking, double pump the puck to release the target.
1.
The tracker will automatically reduce the tracking gate size by 25%,
eliminating the less interesting area around the outside of the region you are
most interested in.
Quickly double pump the puck to reacquire the target and put the tracker into
2.
tracking mode using a smaller tracking gate.
Using the Joystick During Target Acquisition
During target acquisition, you can hold down the MENU button and move the
puck to increase or decrease the size of the acquisition region. The exact
motions you use vary depending on whether Twist-to-Pan Mode on the System
Setup menu is enabled (see page 56).
Note: The setting of Joystick Mode does not affect how you move the joystick
while tracking.
You move the puck forward (fore) to increase the vertical dimension of the
acquisition window, and backwards (aft) to reduce it. When Twist-to-Pan Mode is
enabled, you twist the puck counter clockwise to increase the horizontal
dimension of the acquisition region, and turn it clockwise to decrease it. When
Twist-to-Pan Mode is disabled, you move the puck to the left and right to do the
same thing.
The changes you make to the size of the acquisition region apply only to the
current tracking session. If you engage a target and then double pump the
joystick to release the target, the acquisition region will redisplay at the initial
default size (unless you quickly reacquire, as described in the previous section).
You also can hold down the MENU button and cycle through the four tracking
algorithms using puck movements.
