Vision Devices Vision Devices Cameras The ACE Sight software supports the following cameras: l Basler 1394a l Basler 1394b l Basler Gigabit Ethernet l Emulation devices Calibration You should calibrate the camera before you create any vision tools. The basic camera cal- ibration is a "spatial" calibration that corrects for perspective distortion, lens distortion, and defines the relationship between the camera pixels and real-world dimensions. You can perform this calibration with just a camera and a calibration grid (or fixed-pixel cal- ibration). See See "Standalone Camera Calibration". NOTE : The offset of the camera from the robot or other equipment is not part of this cal- ibration.
That information is obtained during the robot-to-camera calibration. See ACE Sight Calibrations on page 625. Emulation Devices 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). Virtual Cameras The ACE Sight software uses a Virtual Camera to interface with either a physical camera or an emulation device.
This allows the vision tools to interface with any image input in the same way, through the virtual camera. A virtual camera can be added to the workspace at the same time that you add a camera or emulation device by checking the "Add Virtual Camera" box.
