- MVTec Embedded Vision HPeek Demo
- How to Get Started
MVTec Software GmbH provides HPeek which proves the essence of MVTec HALCON with a selected number of Machine Vision software and solutions for a broad variety of industries.
It is suitable for embedded systems such as the Toradex computer on module (SoM) offerings. Since it runs on top of Toradex' standard Linux BSP, you have the added value of MVTec HALCON's on top of a reliable system on module solution.
Watch our joint webinar with MVTec: An introduction to Embedded Vision with MVTec HALCON
HPeek
MVTec HALCON Toradex Easy Installer image format offers HPeek, a tool to demonstrate HALCON machine vision and HALCON image processing performance and key features regardless of a commercial license. The provided demo runs a series of image processing algorithms applied to offline images calculated in the target embedded system device, e.g. plant segmentation demo shown below.

Develop and Deploy Applications
MVTec HALCON provides a highly interactive Integrated Development Environment (IDE) for Machine Vision compatible with Linux, Windows and macOS operating systems in the host and Linux, Windows CE, Android and other operating systems in the target: HDevelop development environment enables a fast time-to-market and ease of use with a large set of examples, some of them shown in HPeek.
A HDevelop program can be easily integrated into your application since it has interfaces with C, C++, C# and VB.NET where it is possible to access all of its operators to perform machine vision procedures in a few lines of highly optimized code, once it is GPU accelerated and has full support of available instruction sets (neon support for ARM platforms).
Next Steps
For more information about how to develop a HALCON Application head over to the extensive MVTec Documentation.
Displays and Monitors used in Embedded Systems are available in a myriad of configuration possibilities - resistive, capacitive or without touch, single or multi touch, different resolution, density of pixels, pin-out and clock frequency are some examples.

Today, we want to share our first screencast using Asciinema with you. The screencast is recorded on a per-character-basis directly from the Windows terminal. This allows you to copy'n'paste commands and output as needed, saves bandwidth and looks sharp and pretty.
Part 1: Setup a Raspberry Pi 3 from scratch
We assume you have bought a new Raspberry Pi 3 together with a Micro USB power supply (at last 2.1A) and a Micro SD card. We also assume that the Micro SD card is formatted as FAT32 and available as drive D: on an updated Windows 10 installation. Watch the screencast (explanations follow in the next section):
Halcon Software
Details and explanations
- Download NOOBS from https://www.raspberrypi.org/downloads/noobs/.
- Unzip to Micro SD card (drive D:)
- Automatically have SSH enabled directly after the Raspbian installation has finished by creating a file ssh in D:
- Make sure Raspbian OS will be installed automatically (disable prompting for other OS):
- Remove other OS from SD card:
- append silentinstall to the first (and only) line in D:recovery.cmdline
- Remove SD card, insert into Raspberry Pi, connect Ethernet and Power. Wait. Raspbian OS will be installed automatically. This took about 10minutes with our system.
- While Raspbian installation is running, make sure that you have installed the Linux Subsystem for Windows to use SSH
- as an alternative, install PuTTY and use pscp instead of scp and putty instead of ssh.
- The Raspberry Pi will become available with hostname raspberrypi on the network.
Default user: pi, Default password: raspberry .
Setup and test HALCON 13 on a Raspberry Pi 3 with Raspbian
Launch bash on the Linux Subsystem for Windows by typing bash in the Windows Start Menu (will match Bash On Ubuntu on Windows). Then:
Details and explanations
- Copy HALCON (Linux) to your newly setup Raspberry Pi:
- As this is your first connection to the Raspberry Pi, type yes to add raspberrypi to your list of known hosts.
- Default user is: pi, Default password is: raspberry
- SSH to
raspberrypi
: - Change default password for user pi:
- Unpack HALCON to /tmp/halcon:
- Install HALCON to /opt/halcon/halcon-13.0:
- During installation: Accept license, install to /opt/halcon/halcon-13.0, create target directory, choose Full (3) installation, install English documentation (1).
- Remove temporary installation files:
- Add a new command h13 to your .bashrc file. This allows to type h13 in the shell to setup your environment for HALCON 13.0:
- Add this to your .bashrc
- Try:
- Enable license mechanism
- Copy your license obtained from MVTec from the host computer (Windows 10) to the Raspberry Pi:
- attach your HALCON USB dongle
- make sure the dongle appears as USB HID device (WIBU-SYSTEMS AG CodeMeter):
- copy udev rule for dongle and reload udev system:
- Run hbench and hbench -parallel. Example output:
