8.3.2 Acquisition Status Indicator

If a camera receives a software acquisition start trigger signal when it is not in a "waiting for

acquisition start trigger" acquisition status, it will simply ignore the trigger signal and will generate

an acquisition start overtrigger event.

If a camera receives a software frame start trigger signal when it is not in a "waiting for frame start

trigger" acquisition status, it will simply ignore the trigger signal and will generate a frame start

overtrigger event.

If a camera receives a software line start trigger signal when it is not in a "waiting for line start

trigger" acquisition status, it will simply ignore the trigger signal and will generate a line start

overtrigger event.

The camera’s acquisition status indicator gives you the ability to check whether the camera is in a

"waiting for acquisition start trigger" acquisition status or in a "waiting for frame start trigger"

acquisition status or in a "waiting for line start trigger" acquisition status. If you check the acquisition

status before you apply each software acquisition start trigger signal, software frame start trigger

signal and software line start trigger signal, you can avoid applying trigger signals to the camera

that will be ignored.

The acquisition status indicator is designed for use when you are using host control of image

acquisition, i.e., when you are using software acquisition start, frame start, and line start trigger

signals.

To determine the acquisition status of the camera via the Basler pylon API:

 Use the Acquisition Status Selector to select the Acquisition Trigger Wait status or the Frame

Trigger Wait status or the Line Trigger Wait status.

 Read the value of the Acquisition Status parameter.

If the value is set to "false", the camera is not waiting for the trigger signal.

If the value is set to "true", the camera is waiting for the trigger signal.

You can check the acquisition status from within your application software by using the Basler pylon

API. The following code snippet illustrates using the API to check the acquisition status:

// Check the acquisition start trigger acquisition status

// Set the acquisition status selector

Camera.AcquisitionStatusSelector.SetValue

( AcquisitionStatusSelector_AcquisitionTriggerWait );

// Read the acquisition status

bool IsWaitingForAcquisitionTrigger = Camera.AcquisitionStatus.GetValue();

// Check the frame start trigger acquisition status

// Set the acquisition status selector

Camera.AcquisitionStatusSelector.SetValue

( AcquisitionStatusSelector_FrameTriggerWait );

// Read the acquisition status

bool IsWaitingForFrameTrigger = Camera.AcquisitionStatus.GetValue();
