Vision for pick and place machine

Does EMC support using vision to actually adjust the path? I am looking at building a SMT P-N-P and am trying to decide if I can use vision to adjust for the orientation of the part using a "look up" camera like the "big boys" do. Also would like to be able to use a "look down" camera to find the fudicals to orient the board.

I read a post somewhere discussing vision, but I could not decide if EMC actually processes info from it or if it can just be displayed for the user.

I was afraid that was gonna be the answer. Jogging could work for the fudicals, as this could be a setup thing. But the parts would need to be "found" by software.

Do you know of any software that can be called from the M1xx?

Yes, thats the WIKI that made me think maybe this is possible. Here is the use for this:

lets say the machine is placing a 14mmx14mm TQFP part. the part will not be EXACTLY in the correct position in the tray it comes in. So the machine goes over and picks up the part, in what it believes to be the center of the part. Then it zips over to the camera which snaps a pic of the part. in the next moments, the image is processed and the machine corrects for the small mis-alignment of the part. (imagine in the tray the part was twisted just a bit. the image processor will tell the machine to twist some amount to bring the part square.) This could all be done by mouse clicks, and may be a good way just to start, but eventually one will get real tired of doing each part that way.

As for the comment by John, Now that I think about it, it does seem easier to process the raw data from th ccd then to process the coded image files. Maybe I need to go check up on reading the CCD directly.

ooh, hey this is interesting.

In cine vfx we can motion track chroma keyed elements over time in a video (Nuke/AE etc...) - easily up to PAL spec we can do the same in real time (Max/Jitter/Processing etc...) ...

You could make yourself a chicken:

I start one project for this some time ago, but I didn't finish the integration with emc2,

Wow that's good stuff! I guess from the thread you are using it as an input device based on mouse clicks? Any thoughts on doing actual vision? I think the pick and place machines use IR as when looking at an output on screen, the leads are almost white, the body is black, and the rest of the background is gray. To me this makes perfect sense. There is no software filtering needed, just line ut the white dots.
So after I get a machine up and running, I will start playing with cameras.
