Re: how to create simple machine vision using webcam and cRIO?
Following along the same lines, if you are going to use vision to detect a transparent part, you will want to manipulate the arrangement to make it easier and more accurate. Perhaps you can place the light and camera at an obtuse angle to the mold so that the transparent part "shines" or has a highly reflective surface compared to the empty mold. This will likely be with the light at a shallow angle and the camera at a similar angle on the other side. You may also want to play with the color of lighting and/or filters. Since everything is likely to be very warm on the machine, you may want to look at the blue end of the light spectrum to see how the part transmits or reflects UV light.
And as Ryan mentioned, keep your eyes open for a nonvision solution as it is almost always less expensive.
