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.
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.
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.
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?
