Adding an Emulation Device Specifications for a Grid of Dots Target l Dots should be round and well-contrasted. l The recommended pitch range is 4 to 12 mm. l Dot pitch must be the same in both X and Y axes. Dot pitch should be four times the dot radius. l The target should cover the entire field of view. l For best results, targets should be of high photo quality on a stable medium, not printed. NOTE : You should measure the pitch of your dots after printing a grid, to confirm that your printer did not scale the grid. If the dots are not exactly the pitch you think, your camera calibration will be inac- curate.
Adding an Emulation Device An Emulation Device is a stored collection of images, which the ACE Sight software can treat as if they were coming from a "live" (physical) camera. This is mostly used for working offline, when a camera is not available, or when viewing images from an application at a remote facil- ity (you need a copy of the workspace and the sample images). To add an Emulation Device: 1. Right-click in the Tree structure of the Workspace Explorer and select: New > Vision > Device > Emulation Device ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 327
