My July column (“Calibrate camera coordinates and colors”) described techniques you can use to calibrate vision systems. In some cases, though, basic calibrations do not suffice. General-purpose ...

Finding the right set of lenses for your machine vision system can be a daunting task. Wiebke Marzahn of Sill Optics addresses some common concerns by breaking the puzzle down into a number of key ...

The SOD-10X, a new telecentric micromachine lens from Moritex, delivers up to 20X magnification without affecting resolution or numerical aperture. The Super Optical Device has 1.5-mm spatial ...

Perspective errors, or parallax, are part of everyday human experience. In fact, they let the brain interpret the 3D world. For example, closer objects to appear relatively larger than those away.

Although perspective has been lost, a telecentric lens presents images ideal for measurement and analysis. A further refinement, the double telecentric lens, presents parallel light rays to the focal ...

Precision manufacturing relies on accurate and precise dimensional metrology for process monitoring and control. Simply put, it is impossible to sustain a manufacturing process that is both accurate ...

Telecentric lens have constant magnification when changing in objective distance. There is no perspective error when viewing 3D object. It is widely used in machine ...

This work required the development of a telecentric lens plug-in for DIRSIG. This plug-in would closely mimic DIRSIG's OrothImage plug-in, however, still allow for depth of focus effects as seen from ...
