Impact Acquire SDK C++
GenICamSequencerParameterChangeAtRuntime.cpp

Parts of the GenICamSequencerParameterChangeAtRuntime program are based on the ContinuousCapture.cpp example. The sample shows how to configure the GenICam™ SFNC Sequencer Control from an application. In addition to that it explains how change certain sequencer related parameters in a very fast and efficient way.

Note
This sample is not meant to work with every device as it uses custom features only supported by a limited range of devices!

Sometimes it is necessary to modify certain sequencer parameters. The standard way to do this is to

This depending on the device, the system and the application can take quite some time. This is where the feature explained in this example might come in handy. The mvIMPACT::acquire::GenICam::CustomCommandGenerator class is capable of sending commands to a device that can directly modify one or more parameters in one or more sequencer sets without stopping the running sequencer or the acquisition engine. As this happens fast but asynchronously an application must accept that changes applied this way might become effective not with the next but with the 2nd frame captured after the parameter change applied but most of the time this is OK.

Program location
The source file GenICamSequencerParameterChangeAtRuntime.cpp can be found under:
%INSTALLDIR%\apps\GenICamSequencerParameterChangeAtRuntime\
Note
If you have installed the package without example applications, this file will not be available. On Windows® the sample application can be installed or removed from the target system at any time by simply restarting the installation package.
GenICamSequencerParameterChangeAtRuntime example:
  1. Opens a GenICam™ compliant device.
  2. Configures the sequencer if available.
  3. Captures a sequence as configured.
  4. Applies changes to the sequencer program while it is running.
Console Output
#############################################################################
# This example runs 6 SequencerSets, where the ExposureTime varies between
# the SequencerSets. There are two modes. The example starts in random mode,
# where ExposureTime as well as OffsetX and OffsetY is changed every 100
# images randomly. The manual mode allows to change these parameters using
# keys:
#         [Space]       (re)start manual mode
#         [r]           go back to / restart random mode
#
#         [Left]        move AOI to the left
#         [Right]       move AOI to the right
#         [Up]          move AOI upwards
#         [Down]        move AOI downwards
#
#         [PageUp]      increase ExposureTime by 10ms
#         [+]           increase ExposureTime by 1ms
#         [-]           decrease ExposureTime by 1ms
#         [PageDown]    decrease ExposureTime by 10ms

How it works
After getting the device from user input the sample tries to
  1. set the mvIMPACT::acquire::Device::interfaceLayout to mvIMPACT::acquire::dilGenICam
    pDev->interfaceLayout.write( dilGenICam );
  2. set the mvIMPACT::acquire::Device::acquisitionStartStopBehaviour to mvIMPACT::acquire::assbUser
    pDev->acquisitionStartStopBehaviour.write( assbUser );
    and to
  3. open the device by calling
    pDev->open();
  4. The sample shows, how to configure the Sequencer Control according to the SFNC (Standard Features Naming Convention) however as the things that can be done using the Sequencer Control are very specific and application dependent this example might not work with every GenICam™ compliant device as some features are just assumed as being available.
  5. Every 100th frame captured the application will dynamically change sequencer settings while the acquisition and the sequencer continue to run

The important bit of this application is the following function:

//-----------------------------------------------------------------------------
// This function will configure the sequencer on the device at runtime without
// stopping the acquisition of the sequencer program. This approach is much faster
// than the usual way.
void configureSequencerAtRuntime( ThreadParameter* pTP, const bool boApplyOriginalData )
//-----------------------------------------------------------------------------
{
try
{
if( boApplyOriginalData )
{
for( size_t i = 0; i < s_SequencerData.size(); i++ )
{
cout << "Will set the exposure time of sequencer set " << i << " to " << s_SequencerData[i].exposureTime_us_ << "us." << endl;
pTP->ccg.queueSequencerSetValueModification( static_cast<int64_type>( i ), sspExposureTime, s_SequencerData[i].exposureTime_us_ );
pTP->ccg.queueSequencerSetValueModification( static_cast<int64_type>( i ), sspExposureTime, s_SequencerData[i].exposureTime_us_ );
}
}
else
{
for( size_t i = 0; i < s_SequencerExposureDataForRuntimeChange.size(); i++ )
{
cout << "Will set the exposure time of sequencer set " << i << " to " << s_SequencerExposureDataForRuntimeChange[i] << "us." << endl;
pTP->ccg.queueSequencerSetValueModification( static_cast<int64_type>( i ), sspExposureTime, s_SequencerExposureDataForRuntimeChange[i] );
}
}
pTP->ccg.sendCommandBuffer();
}
catch( const ImpactAcquireException& e )
{
std::cout << "An error occurred while setting up the sequencer for device " << pTP->pDev->serial.read()
<< "(error code: " << e.getErrorCodeAsString() << ")." << endl;
s_boTerminated = true;
}
}

This function uses the mvIMPACT::acquire::GenICam::CustomCommandGenerator to generate custom commands understood by the device that will result in sequencer sets to change to the desired values. Refer to the documentation of the mvIMPACT::acquire::GenICam::CustomCommandGenerator to read more about how the commands are generated and what can be done using this class.
