Camera Trigger
In the Device Control Drawer
The Camera Trigger tool can force the Impact device to acquire an image without a hardware trigger. It is
primarily used to vary the lighting by snapping a second image with different strobe settings.
In the example below, the task is initiated when the device acquires the initial image of the dark areas of a
part using the standard strobe settings (the Task Trigger type is ImageIn Event). This first image is automat-
ically assigned a negative TriggerId number by the Impact device and queued to be processed. The Branch
tool determines if the TriggerId is positive or negative. If the TriggerId is negative (it is the first image), the
Camera Trigger tool is run.
When the Camera Trigger tool runs, the device acquires an image of the lighter areas of a part with a shorter
strobe settings (less light) which triggers the ImageIn event and queues that image. The Camera Trigger tool
assigns the image a positive TriggerId number (which was entered in its Trigger ID input property). When
the task finishes processing the first image it runs again (because the Camera Trigger tool caused an ImageIn
event), and the Branch tool takes the True branch and the Sample Top tool processes the second image. In
this example, the Branch tool expression is
TriggerID < 0
