Image Acquisition Control AW00104701000

108 Basler scout light GigE

Camera.AcquisitionStart.Execute( );

// Frame acquisition will start when the externally generated

// frame start trigger signal (ExFSTrig signal)goes high

The following code snippet illustrates using the API to set the parameter values and execute the

commands related to hardware frame start triggering with the camera set for continuous frame

acquisition mode and the trigger mode for the acquisition start trigger set to off. We will use the

trigger width exposure mode with input line 1 as the trigger source and with rising edge triggering:

// Set the acquisition mode to continuous frame

Camera.AcquisitionMode.SetValue( AcquisitionMode_Continuous );

// Select the acquisition start trigger

Camera.TriggerSelector.SetValue( TriggerSelector_AcquisitionStart );

// Set the mode for the selected trigger

Camera.TriggerMode.SetValue( TriggerMode_Off );

// Disable the acquisition frame rate parameter (this will disable the camera’s

// internal frame rate control and allow you to control the frame rate with

// external frame start trigger signals)

Camera.AcquisitionFrameRateEnable.SetValue( false );

// Select the frame start trigger

Camera.TriggerSelector.SetValue( TriggerSelector_FrameStart );

// Set the mode for the selected trigger

Camera.TriggerMode.SetValue( TriggerMode_On );

// Set the source for the selected trigger

Camera.TriggerSource.SetValue ( TriggerSource_Line1 );

// Set the trigger activation mode to rising edge

Camera.TriggerActivation.SetValue( TriggerActivation_RisingEdge );

// Set for the trigger width exposure mode

Camera.ExposureMode.SetValue( ExposureMode_TriggerWidth );

// Set the shortest exposure time -

// the shortest exposure time we plan to use is 1500 us

Camera.ExposureTimeAbs.SetValue( 1500 );

// Prepare for frame acquisition here

Camera.AcquisitionStart.Execute( );

while ( ! finished )

{

// Frame acquisition will start each time the externally generated

// frame start trigger signal (ExFSTrig signal)goes high

// Retrieve the captured frames

}

Camera.AcquisitionStop.Execute( );

You can also use the Basler pylon Viewer application to easily set the parameters.

For more information about the pylon Viewer, see Section 3.1 on page 25.
