Remember Lenses and Lights
Jon Titus   2/21/2012 11:52:59 AM
NO RATINGS
People interested in using vision--2D or 3D--also must understand the importance of choosing the proper lenses and of evaluation a variety of lighting options.  It's easy to think about lighting in terms of gross illumination, but lighting choices also involve attenuating reflections, eliminating shadows, the proper use of color to highlight specific characteristics, and so on. In some cases, a 2D vision system can use shadows from directional lighting to determine heights as well as positions. Microscan has several helpful technical papers for people interested in lighting techniques: www.microscan.com/en-us/home.aspx.

A Google search will list good resources that describe lighting techniques and provide visual examples. Edmund Optics (www.edmundoptics.com) has many helpful tutorials on lenses as does Schneider Optics (www.schneideroptics.com/info/industrial.htm).

Other ways of obtaining the 3D data...

There are several cameras out in the market like the Photonfocus ones, containing the SAL3D Peak detector for 3D machine vision inside.

Another good option to obtain 3D data would be using a 2D camera together with a framegrabber containing laser detection, like the ones provided by SiliconSoftware through their Visual Applets tool, or obtaining it by using a laser-camera system together with a 3D machine vision software.

Latest Analysis
If you’ve noticed the recent news about electric cars and batteries, then it’s easy to wonder about the continuing wisdom behind public subsidies for EVs.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
A group of collaborators wants to recast MacGyver or a show similar to it with a female protagonist as part “The Next MacGyver” competition, in order to get young girls interested in STEM fields.
Biomimicry and 3D printing have come together in new swarming ant and butterfly robots that act very much like their insect counterparts, the inventions of German robotics firm Festo.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
