Target Tracking - Gemini 720is Product Manual

Gemini Software Operation
The distance between the Distance Marker and Set Point is displayed in the bottom
right of the Gemini data view (see image below). The displayed values are calculated as:
Distance (X, Y) = (Distance Marker - Set Point)
The Distance Marker range/ Y coordinate may be updated from an external sensor. Enabling
the Distance Range from Sensor button will update the value whenever a configured
sensor message is received. See Appendix E, Gemini Software String Decode for the
appropriate Marker Range decode options.

5.2.7. Target Tracking

Tracking provides a mechanism of highlighting objects and following their
Target
movement over subsequent sonar frames. Once enabled, targets will be automatically
determined and tracked when selected.

Note
In order to click and drag the markers the click must be within the head image.
For example, if a marker is at location (0, 0) the clickable area is fairly small and
care must be taken to click the correct area. In this case, the Distance Marker
line may reach past the head image boundary and would only be clickable where
it overlaps the head image.
