The "alternative" version of LitePlacer (rmod aka. Knaster's modifications) supports all sorts of fiducials by applying pattern matching.

Basically you take a picture of the fiducial, save that as a pattern and software can find it later using vision.

I am unsure if Juha's main branch supports this; I think it does not.

Maybe @Juku can fill in?

I have friend who work for mydata p&p and i cas ask him to do that. but it could be cool to spread this option for all from liteplacer community. I think that its not tricky to implement into sw and takes max hour.

It is possible to implement into sw patern recognition?

I'm working on this right now. It wasn't even close as simple as I thought it would be, so give me a few days. I'll release the feature as soon as this is done.

I'm seldom this far off in my estimates... Anyway, using non-standard fiducials or board features as fiducials is now much better: round, rectangular or both, adjustable tolerance and optional manual confirmation. See downloads page.
