Remember Lenses and Lights

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.
