Do you have small resolution bar codes to read but don't get any good results? Then please try our new feature – the subpixel bar code reader.

This month’s technical article continues our introduction to XYZ-mappings. In the last article, we answered the question "What are XYZ-mappings?" and gave a short preview towards "Why is using XYZ-mappings beneficial for many 3D applications?".…

In the context of 3D applications in HALCON, you have surely already heard the terms “3D mappings”, “XYZ-mappings” or “XYZ-images”. Many 3D sensors provide these XYZ-mappings along with the point cloud. In this and follow-up technical articles, we…

You want your new deep learning application to be successful? Then you should be careful with your data handling. In every machine vision application it is important to work with “high-quality” image data. However, in case of deep learning…

Most of the easyTouch tools available in MVTec MERLIC are optimized for processing byte images and generally do not work as expected for other pixel types, such as int1', 'int2', 'int4', 'int8', 'real', and 'uint2'. This is due to the extreme gray…

With the help of deflectometry you can easily inspect flat but also curved specular surfaces. Defects like scratches, bumps, cracks, and dents can be detected robustly and fast. Deflectometry is used in various industries like microelectronics,…

Deep learning technologies allow a wide range of applications for machine vision. Based on these technologies, MVTec offers various operators and tools within HALCON and MERLIC – often in combination with embedded boards and platforms (more…

In the digital age of smartphones and tablets, the control of devices via a touch screen became second nature to us. Little by little, this revolutionary new technology is adapted by industry as well. Often, we are asked whether it is possible to…

Deflectometry is useful for inspecting reflective (specular) surfaces. These surfaces are tricky to inspect with other methods, due to a mirror image appearing on the surface. Chapter 8 in the HALCON Solution Guide I describes the principle of…

The parameter "Greediness" defines a tradeoff between speed and completeness. On the one hand, the search speed can be increased by discarding candidates earlier based on a less strict criterion, while on the other hand, it might occur that no…
