How to prepare 3D height images for further processing with MERLIC’s standard tools

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…

Increasing Speed in Deflectometry Set-Ups

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…
