I have set up one such system, that made use of a reticule generator "box" in line between a CCD camera with a magnification lens (not attached to a microscope)
The essential part is fixing the camera in such a way that it is immovable. If that aspect is done well, a pair of cross lines drawn on the video monitor work just fine. I liked the idea of "fixed off set" rather than "through the spindle center" orientation. This link shows an interesting camera, and does not require a PC ! http://www.youtube.com/watch?v=zb0IQPHbU0g Cal ----- Original Message ----- From: "Kirk Wallace" <[email protected]> To: "Enhanced Machine Controller (EMC)" <[email protected]> Sent: Wednesday, September 15, 2010 12:18 Subject: [Emc-users] Video Accuracy >I have a project that requires being able to locate a scribed line very > accurately(, worm gear cutting without a rotary table).
