Qioptiq unveils vision metrology system
Able to zoom across its 12.5:1 magnification range in less than 1 s, the Fetura noncontact vision metrology system from Qioptiq approaches the speed of digital zoom lenses without the loss of resolution inherent in digital zooms, according to the manufacturer. Fetura's PowerMetrix software provides color edge detection and includes tools for image processing, coordinate data acquisition, and geometric calculation. The all-LED illumination is programmable for intensity, direction, and angle of incidence. The Fetura system comes in four models, with stage travel ranging from 200x200x200 mm to 800x800x250 mm. www.qioptiqlinos.com.
Cameras offer fast frame rates
Outfitted with Kodak's progressive-scan interline CCD image sensors with Quad-Tap technology, the SX series of cameras from Baumer targets industrial applications requiring resolutions of 1, 2, or 8 Mpixels at rates of up to 120 fps. All SX cameras have a base Camera Link interface and are available in both monochrome and color versions. To simplify the integration of these cameras into existing operating software, Baumer offers a software development kit containing a generic application programming interface, code examples, and programming documentation. www.baumer.com.
Cognex expands vision software
Release 6.0 of VisionPro hardware-independent software from Cognex adds support for very large camera images and nonconventional sources. In addition, VisionPro 6.0 offers calibration and image correction for line-scan cameras and expanded ID reading capability for 2-D codes.
The software can now acquire images up to 16 bits in depth, which enables the use of sources such as 3-D profilers, thermal cameras, and x-ray imagers. Release 6.0 also works with Microsoft 64-bit operating systems, which allows it to accommodate larger cameras and greater pixel depth.
Also new is a high-accuracy calibration tool for use with line-scan cameras. A single calibration-board image is sufficient for correcting camera distortion and camera displacements, such as rotation and tilt. Finally, VisionPro's ID symbol reader now reads 2-D codes up to 144x144. www.cognex.com.
Frame grabber fits ExpressCard slot
The PIXCI ECB1-34 from EPIX is a base Camera Link frame grabber that plugs into an ExpressCard/34 or ExpressCard/54 slot in a notebook computer and boasts sustained transfer rates of 200 Mbytes/s and burst transfer rates of up to 250 Mbytes/s. You can use the frame grabber with line-scan or area-scan cameras operating in either free-run (continuous) or controlled (triggered) mode. The PIXCI ECB1-34 offers software-selectable bit packing to decrease the data rate to the ExpressCard bus and to conserve storage space when capturing 10-bit or 12-bit pixels.
The companion XCAP software comes in three versions: Lite, LTD, and STD. XCAP-Lite provides camera control and image capture with no software development. It is limited to a 64-Mbyte frame buffer. XCAP-LTD supports up to a 4-Gbyte frame buffer on 32-bit operating systems or an 8-Gbyte frame buffer on 64-bit operating systems. XCAP-STD adds video-to-disk capture limited only to the size and speed of the hard-drive system and can capture to the limit of the available notebook memory. www.epix.com.
