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 ...

Barrington, NJ. Edmund Optics is now offering its TECHSPEC compact telecentric lenses with six new models with working distances of 220 mm and 300 mm. Featuring a telecentric design across all ...

In fact, they let the brain interpret the 3D world. For example, closer objects to appear relatively larger than those away. This phenomenon is also present in imaging systems in which the size of an ...

The microscope combines a big telecentric photolithography lens with a large tube lens to create sharp, detailed images of large and curved samples. These lenses project the image onto a flat array of ...

Working on a machine vision project requires understanding each part of the system, including light sources, frame grabbers, and computers. Here is a primer on two essential machine-vision terms.

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 ...
