HALCON

Introduction

For more information about HALCON by MVtec, we refer to the product owner´s online presence: https://www.mvtec.com/products/halcon/

HALCON can be pre-installed on the camera via /opt/halcon and can be acceses via the path variable $HALCONROOT, please contact our sales.

HALCON for ARM-based Platforms

The offical MVTec document "HALCON for ARM-based Platforms" describes the process of "compiling/cross-compiling" of HALCON applications and is linked below.

https://www.mvtec.com/fileadmin/Redaktion/mvtec.com/documentation/manuals/arm_based_platforms.pdf

The document is divided into chapters. For a better orientation we give a short overview:

Chapter 1 Using HALCON on ARM-based Platforms

Gives a general overview of using HALCON on ARM-based Platforms.

Chapter 2 Getting Started

Discribes the process of installing HALCON to an ARM-based Platform and can be skipped since the HALCON tools are pre-installed both on iam and the virtual machine.

Chapter 3 Creating Applications

Describes the process of "compiling/cross-compiling" of an HALCON application.

HALCON installation on iam

In order to aquire live frames, the halcon-runtime and halcon-GenICamTL interface has to be installed on the camera.
Halcon environment variables must be set in order for HALCON to work.
Edit halcon.sh (<directory you installed HALCON in, e.g., /opt/halcon>) accordingly to your installation and copy it to /etc/profile.d

halcon.sh:

HALCONARCH=aarch64-linux; export HALCONARCH
HALCONROOT=<directory you installed HALCON in, e.g., /opt/halcon>; export HALCONROOT
HALCONEXAMPLES=${HALCONROOT}/examples; export HALCONEXAMPLES
HALCONIMAGES=${HALCONROOT}/examples/images; export HALCONIMAGES
PATH=${HALCONROOT}/bin/${HALCONARCH}:${PATH}
export PATH
if [ ${LD_LIBRARY_PATH} ] ; then
  LD_LIBRARY_PATH=${HALCONROOT}/lib/${HALCONARCH}:${LD_LIBRARY_PATH}
  export LD_LIBRARY_PATH
else
  LD_LIBRARY_PATH=${HALCONROOT}/lib/${HALCONARCH}; export LD_LIBRARY_PATH
fi
export XILINX_XRT=/usr
GENICAM_GENTL64_PATH=/opt/synview/cti64

Use HALCON on iam

Be sure that the iAMGigEServer is stopped, before you execute halcon-framegrabber-apps.

HALCON Examples on iam

Open an SSH Shell connection to the camera. In some cases X-Server support is required.

ssh -Y root@192.168.1.10

There are some examples pre-installed to iam. They can be found here:

cd /home/root/040530_test_halcon

On top of the file system see for README.md.

There is detailed information about the provided samples.

Structure of the test_HALCON folder:

The folder contains the file system below. The three examples have a similar file structure.

Description of samples:

test_halcon_aniso_test:

This sample is derived from find_aniso_shape_model.hdev (MVTec Software GmbH).
This sample is designed for testing the performance of the FindAnisoShapeModel() function.
With 50 loops a mean value of the consumed time of FindAnisoShapeModel() is evaluated.

OPTIONS:

NO_WINDOWS ; if defined no windows are shown

For executing this sample make sure that smd*.png files are inside <directory you installed HALCON>/examples/images/smd

test_halcon_live_view:

This sample is derived from error_handling_timeout.cpp (MVTec Software GmbH).
This sample is designed for testing the live view of the iam platform.

OPTIONS:

SAVE_IMAGE ; if defined, a image is saved at the end of program
SET_EXPOSURE_TIME ; if defined, a exposure time is set

test_halcon_sw_trigger:

This sample is derived from error_handling_timeout.cpp (MVTec Software GmbH).
This sample is designed to show the software trigger functionality.
This sample aquires 100 software triggered frames.
No live view is implemented.

OPTIONS:

NONE

Execution of one of the provided HALCON examples

The binaries of the prebuild examples can be found in the ../bin directory of each example project. The test_halcon_live_view can be executed applying the commands below. The other two examples can be executed in the same way.

Compiling the provided HALCON examples

It is possible to compile the examples on a Linux Host system (e.g. by using the provided virtual machine image) or native on the camera (over OpenSSH) both using makefiles.

The next section describes the process of building the software trigger project as an example.

Build e.g. the software trigger example

Navigate into the makefile directory

Remove the prebuild binary by executing the command make make clean and build it from source by make .

The compiled binary can be found in the ../bin directory and can be executed as follow

Building your own HALCON examples:

Prepare Makefiles

Possibly the easiest way is to copy the complete folder of one of the examples and rename it to your project name:

Now edit and rename the given source file from the director your_project_name/source/ or simply replace it by your own cpp file.

Edit the makefile as shown below in line 38 with regard to the naming of your cpp source file.

Using make command

Navigate into the makefile directory and execute the make command.

The binary can be found now in the ../bin directory and can be executed by the commands below.
