The LV-SDS Halcon driver is currently available in versions for Windows and Linux operating system. It can be used under all flavors of these operating systems that are supported by both the LV-SDS and Halcon. Check also the architectures and environments (especially compiler versions) supported by LV-SDS and Halcon. Detailed information about LV-SDS system requirements is provided in Installation and configuration guide. System requirements for the Halcon and ActivVisionTools libraries are listed on the MVTec Software GmbH website.
Cs go cheats for mac. The LV-SDS Halcon driver is available for all Halcon versions from 5.2 and higher. It is however recommended to use the latest Halcon version whenever possible.
The LV-SDS Halcon driver is installed as a part of regular LV-SDS installation, which is described in Installation and configuration guide.
Under Windows, it is necessary to explicitly check the “Halcon support” option during the LV-SDS setup.
The corresponding
.dll
files are installed in the LVSDSHOME
bin
, where LVSDSHOME
is LV-SDS installation directory, C:LVSDS
by default. The bin
directory is added to the system path as required, so that the Halcon loader can find the libraries. The files are named HFGLeutron.dll
(interface for Halcon versions 6 and higher), respectively parHFGLeutron.dll
(the same for Parallel Halcon). Other .dll
file names (100% compatible) might also be available to keep backward compatibility with older applications.Additionally, the Halcon driver libraries (
Leutron.dll
and others) for Halcon version 5.2 are installed in LVSDSHOME
3rdPartyHalcon5.2bin
directory. Please copy them manually to LVSDSHOME
bin
if you are actually using Halcon 5.2.Under Linux, the Halcon driver is always installed automatically.
The corresponding
.so
files are installed in the /usr/lib/lvsds
directory and links to them are additionally created in /usr/lib
as required, so that the Halcon loader can find the libraries. The files are named HFGLeutron.so

(interface for Halcon version 5.2). Other .so
file names (100% compatible) might also be available to keep backward compatibility with older applications. Ultimate jazz fake book eb pdf merge.It is important to remember, that Linux LV-SDS (and thus also its Halcon driver) is available in variants for multiple versions of the gcc compiler (that are not mutually binary compatible). You can notice multiple .so file versions installed. The basic .so file names (such as HFGLeutron.so ) are always links pointing to the actual version of the Halcon driver library compatible with gcc compiler version that was “default” at the time of LV-SDS installation (the version is determined by calling gcc --version ).This version, however, might not be actually supported by Halcon itself. The links might also become out of date when you update the gcc compiler version on your system. Whenever one of these cases apply or if you need to use a particular (“non-default”) gcc version, please update manually the library links used by your Halcon application (usually HFGLeutron.so ) so that they point to the library compatible with the compiler.See more information about the supported gcc versions in Installation and configuration guide. |

The LV-SDS Halcon driver supports image acquisition from all kinds of Leutron Vision hardware, namely from all families of the frame grabber such as PicPort®-CameraLink or PicPort®-Elite and from our “bus” cameras, such as PicSight®-GigE cameras with Ethernet interface and PicSight®-USB cameras with USB interface. Most of the functionality of these products can be controlled from the Halcon interface. The main features include:
- Support for all types of Leutron Vision hardware using a common programming interface
- Halcon synchronous (
grab_image()
) and asynchronous (grab_image_async()
) grabbing with multiple buffers per grabber to guarantee maximum throughput - Various acquisition modes supporting different functionality:
- basic mode for simple image acquisition with a “free running” camera (without triggers)
- asynchronous reset mode supporting flexible acquisition and shutter time control using external hardware triggers or software triggers
- more
- Advanced settings and control over the hardware's general purpose I/O and optocouplers
- Bayer decoding by means of hardware (when supported by the given model) or software
- Access to additional hardware preprocessing capabilities such as color correction, white balance etc.
- Control of image properties: shutter time, gain, software image cropping etc.
- Serial communication with Camera Link cameras
- Automatic mode adjustment for PicSight®-GigE and PicSight®-USB cameras
The Halcon driver implements all Halcon's frame grabber related operators with exception of
grab_region()
, grab_region_async()
, set_framegrabber_lut()
and get_framegrabber_lut()
. Preprocessing functions of Leutron Vision hardware products, equivalent to the LUT usage, are however implemented by other means, through more elaborate parameter settings.It might happen that some of the very latest LV-SDS features are not always immediately supported by the Halcon driver. In most cases, however, the important features are soon implemented in the Halcon driver interface as well. In case you feel some important functionality is missing, please contact Leutron Vision for the latest information.
For users familiar with LV-SDS programming it might be useful to know that the Halcon driver is fully implemented using the Sequencer DRAL API. This might help understanding the functionality of its interface, Halcon driver just allows to access the standard Sequencer DRAL features using Halcon interface. It also might help with troubleshooting – when something does not work as expected, it can be a good idea to verify (for example using one of our test programs), if the same functionality works well with the pure Sequencer DRAL interface.
It is also important to understand that the Halcon driver is kind of “bridge” between the Sequencer DRAL API and Halcon frame grabber integration API. Linking these two distinct interfaces led necessarily to some compromises. Give me liberty an american history 3rd edition pdf. For example to obtain a Halcon frame grabber handle, you use the
open_framegrabber()
operator, which allows to specify some basic parameters, such as grabber and camera names or connector number. On the other side, to fully initialize a Sequencer DRAL application, it might be necessary to supply many more parameters, which is not possible through the simple open_framegrabber()
call. For example to change the acquisition mode to “asynchronous reset” or to adjust the I/O configuration, you need to use additional calls to the set_framegrabber_param()
operator. Because these parameters are essential for the Sequencer DRAL library, they must be specified before application initialization and not freely at runtime. When setting them from Halcon, the internal Sequencer DRAL object needs to be re-initialized, which in turn can take a while (notably longer than setting some simple runtime parameters such as shutter time). It is thus advisable to adjust all the basic application parameters in the beginning of the application. Otherwise you need to be ready for certain delays.Nevertheless, these limitations affect only the initialization procedure. The runtime performance of the Halcon driver is well optimized and does not introduce any unnecessary delays or bottlenecks.
Lots of samples showing how to use various functionality of the Leutron Vision hardware and software from Halcon applications are installed in
LVSDSHOME
/3rdParty/halcon/scripts
. All the samples are actually a simple HDevelop scripts, each usually demonstrating one particular feature or usage of one particular type of hardware (frame grabber or camera). Every script includes also a brief comment describing its purpose.When searching for a sample showing usage of a particular feature or parameter setting, please search across all the scripts in the directory for the name of the given parameter. The set of scripts is ever growing and thus we do not maintain list of the samples in this document.
Warframe where to farm rare mods. We provide no C/C++ samples for Halcon, they would be identical to the HDevelop scripts. HDevelop is also more suitable for testing and experimenting with the new functionality in an interactive way.
When solving any issues with your Halcon applications using Leutron Vision hardware, please try to determine, whether your problem is related to the Halcon library itself and its use or whether it is related to the hardware interface. For issues related directly to the Halcon, please contact MVTec Software GmbH. When solving issues related to the Leutron Vision hardware and its Halcon driver interface, please follow the steps suggested below:
- Enable the Halcon
do_low_error
system parameter through theset_system()
operator so that additional low level diagnostics can be output. Save those messages to send them with other log files to our support team. - Enable logging of the LV-SDS Halcon driver.The log messages will be sent to the LV-SDS core log file,
prvphlib.log
. Send the log file generated during the problematic session away to be sent later to our support team. - Create the minimal HDevelop script demonstrating the problem. It will help us to reproduce the problem quickly and easily.
- When working under Windows, try to reproduce the problem using the PicPort® and PicProdigy® demo program delivered with LV-SDS. Use its interface for real-time tasks (based on Sequencer DRAL) and use, if possible, the same configuration as when accessing the hardware from Halcon. The user interface of PicPort® and PicProdigy® demo is intuitive and it should not be a problem to jump in using it immediately. Reproducing the problem in PicPort® and PicProdigy® demo can help as a confirmation that the problem is in our interface rather than in your code.
- Follow all the additional general purpose troubleshooting guidelines listed in Support and troubleshooting guide, collect the required log files, then contact our support team.
