AW00123409000 Image Acquisition Control

Basler ace USB 3.0 137

camera.TriggerSource.SetValue ( TriggerSource_Line1 );

// Set the trigger activation mode to rising edge

camera.TriggerActivation.SetValue(TriggerActivation_RisingEdge);

// Set the trigger delay for one millisecond (1000us == 1ms == 0.001s)

camera.TriggerDelay.SetValue(1.78);

// Set for the timed exposure mode

camera.ExposureMode.SetValue(ExposureMode_Timed);

// Set the exposure time

camera.ExposureTime.SetValue(3000.0);

// Execute an acquisition start command to prepare for frame

acquisition

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 acquisition

mode and the trigger mode for the frame burst start trigger set to off. We will use the trigger width

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

// Set the acquisition mode to Continuous

camera.AcquisitionMode.SetValue(AcquisitionMode_Continuous);

// Select the frame burst start trigger

camera.TriggerSelector.SetValue(TriggerSelector_FrameBurstStart);

// 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 );
