Calibration plates are used in measuring applications to clean up optical distortion and ensure precise conversion from pixel to millimeter values. This takes place in the wenglor uniVision 3 software via the Image Calibration module.
In addition, a calibration plate enables simple and fast calibration in robot vision applications. This process also involves coordinate matching, thus eliminating the distortion caused by the optics. For precise calibration, the calibration plate should be completely in the camera’s visual field and cover at least half of the visual field. Paper-printed calibration patterns result in inaccurate calibration. Opaque panels (e.g. ZVZJ001) are suitable for incident light applications, transparent (e.g. ZVZJ005) for transmitted light applications.

HALCON is MVTec’s extensive program library with image processing algorithms. The development environment for HALCON is the HDevelop software.

Yes, the software can also be expanded later with separate license packages.

wenglor uniVision 3 is based on the functionality of uniVision 2, but contains numerous new functions, optimizations and bug fixes. uniVision 2 and 3 also support different devices:

  • uniVision 2: weQube B50 smart cameras, BB1 machine vision controllers, smart 2D/3D profile sensors
  • uniVision 3: smart camera B60

HALCON scripts created in MVTec’s HDevelop software can be loaded in the HALCON Script module in the uniVision software and run on the uniVision product (e.g. B60). The HDevEngine required for this is already pre-installed on the uniVision product.

Yes, the standard software modules in wenglor uniVision 3 software can be combined with HALCON scripts as desired. Flexible data exchange between the modules is possible!

wenglor uniVision 3 thus enables a combination of parameterization and programming:

  • Parametrization:
    Standard tasks can be easily completed with the standard uniVision modules from the uniVision Toolbox 
  • Programming: Complex tasks can be solved in HDevelop with HALCON scripts.

The following data types can be transferred from uniVision modules to the HALCON Script module (inputs) or returned from the HALCON Script module to other uniVision modules (outputs):

  • Iconic variables
    • Images
    • Regions
    • XLDs
  • Control variables
    • Integer
    • Real
    • String

The “Device Robot Vision” module in wenglor uniVision 3 enables direct communication between 2D cameras and robots.

Robot vision is currently supported in wenglor uniVision 3 by the Smart Camera B60. Other devices will follow.

wenglor uniVision 3 enables communication with robots manufactured by UR. Interfaces to other robot manufacturers will follow.

Teaching in objects is easiest in wenglor uniVision 3 using the Pattern Match and Locator modules. 

Various object types can be easily taught in using wenglor uniVision 3 software. The object type can then be sent directly to the robot.


In the Pick and Place application, an individual object height can be set up for each object type so that different object types can be gripped at different heights. 

Any desired offsets in x and y can also be set up in wenglor uniVision 3 software for picking in pick-and-place applications so that the object can be gripped at the tip, for example.

In wenglor uniVision 3 software, data from several different objects can also be found with an image capture and sent to the robot in order to optimize the cycle time for pick-and-place tasks. This means that the robot has to move into the detection position less frequently and can directly grasp other objects that have already been found.

A calibration object is required for calibrating the camera and robot in pick-and-place applications. Professional, rigid and temperature-resistant calibration objects are available in different sizes. Alternatively, you can also print out the calibration sample yourself (PDF download). For the calibration routine, various positions must be taught in in which the camera sees the calibration object so that the relationship between the camera and robot is determined.

If the relationship between the camera and robot does not change, recalibration is not necessary.

uniVision devices run version HALCON 22.11.

HALCON scripts can also be created with other HALCON versions. However, the compatibility information with the version HALCON 22.11 used on uniVision devices must be observed.

Yes, the HDevEngine is already running on uniVision devices. HALCON scripts can thus be run directly on uniVision devices. This allows the focus to be placed on the application solution (software)!

The uniVision ecosystem enables flexible data exchange between all uniVision modules and the HALCON Script module. Numerous interfaces (e.g. PROFINET, EtherNet/IP) are available on the uniVision product. The results from the HALCON Script module can thus be output directly and flexibly via the uniVision interfaces. The flexible web-based visualization also enables flexible and individual display of results from the HALCON Script module – even directly in the image!
