Basler scout GigE 123
Section 9.5.2.2 on page 123 includes more detailed information about applying a software frame
start trigger to the camera using Basler pylon.
For more information about exposure time parameters, see Section 9.7 on page 141.
For more information about determining the maximum allowed frame rate, see Section 9.13 on
page 167 and Section 9.14 on page 171.
9.5.2.2 Setting the Parameters Related to Software Frame Start
Triggering and Applying a Software Trigger Signal
You can set all of the parameters needed to perform software frame start triggering from within your
application software by using the Basler pylon API. The following code snippet illustrates using the
API to set the parameter values and to execute the commands related to software frame start
triggering with the camera set for continuous frame acquisition mode. In this example, the trigger
mode for the acquisition start trigger will be set to off:
// 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
// software frame start trigger signals within the limits imposed by other
// parameter settings).
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_Software );
// Set for the timed exposure mode
Camera.ExposureMode.SetValue( ExposureMode_Timed );
// Set the exposure time
Camera.ExposureTimeAbs.SetValue( 3000 );
// Execute an acquisition start command to prepare for frame acquisition
Camera.AcquisitionStart.Execute( );
while ( ! finished )
{
// Execute a Trigger Software command to apply a frame start
// trigger signal to the camera
Camera.TriggerSoftware.Execute( );
// Retrieve acquired frame here
}
Camera.AcquisitionStop.Execute( );
