Camera Can't Find Part

[[Ri...]]

Hey guys, so I've written a program that uses both tactile sensor and the camera. Every time I run the program, when it gets to the camera portion, it thinks that the part is in the upper left corner, even after a successful alignment. Any thoughts would be appreciated?

Are both sensors calibrated correctly (the camera must have been initialized with the glass plate - but normally only once in a lifetime) and have you run the tactile-optical adjustment? The latter has to be done regularly if you use both camera and tactile in one program. Regularly means at least daily and each time the CMM has been switched off.

Places I have worked in the past used alignments for optics and alignments for tactile, but never combined. The guy in charge had a strong mistrust of the camera tactile offset procedure. Im not saying that it was right, but it did work well, however most of our parts were flat cables, only occasionally did we have 3d geometry to deal with so it wasn't a big deal.

It's true, as long as you don't mix tactile and optical measurements in a single evaluation (like distance from a tactile to an optical bore) you won't need to perform the tactile-optical adjustment. But chances are high, if you're not used to doing it on a regular basis, the day will come when you forget about it.

Open the feature that the camera is searching for and make sure the coordinates are correct.

Also make sure that a stray point didn't accidently get put in there causing the camera to look for that first.

Is a mirrored program or something like that involved? In the past I had issues with mirroring and I think I remember the manual talking about it not being supported.

Generally, what I always disliked about optical measurements in Calypso is that there are portions of the feature coordinates (ussed for camera positioning) stored in the inspection file, which can act as some kind of "offset" to the nominals, but can't be fully edited within Calypso. They always stay at the values they had when they were programmed. Under everyday circumstances this is no problem, but when you start doing "ususual" things (like mirroring or more creative measuring methods with patterns, formulas, parameters etc. involved) this "offset" can become an issue. For example, when you mirror a part, features close to the machine limits can act up because the "offset" coordinates are not getting mirrored and may suddenly lie outside the limits, resulting in an error.
