At this year's Vision Show West, held November 19--21, 2002, at the Santa Clara Convention Center, end users, OEMs, and system integrators met manufacturers of vision systems, cameras, frame grabbers, lighting equipment, lenses, image processors, optical filters, processing accelerators, I/O devices, peripherals, motion control devices, and software. Sponsored by the Automated Imaging Association (a href=http://www.machinevisiononline.org>www.machinevisiononline.org), the Vision Show West was home to more than 100 companies and featured the latest in machine-vision technology. During the tutorials and conference sessions, speakers presented techniques for lighting and optics for machine-vision applications, algorithms, smart sensor technology, and PC-based vision systems.
Conformance to standards
One of the main thrusts of camera exhibitors on the trade-show floor was adherence to standards, most notably the Camera Link standard. Camera Link is a camera-to-frame-grabber interface specification based on an implementation of National Semiconductor's (www.national.com)Channel Link technology (see the Vision Systems Design Camera Link Special Report, May 2002). The specification was developed through an initiative headed by Pulnix America. Camera Link defines a single connector for both the frame grabber and the camera.
Other Camera Link camera vendors included Adimec (www.adimec.com/), which showed a 50-frame/s Megapixel camera and the AVIIVA LVDS camera from Atmel (www.atmel.com/atmel/products/prod41.htm), which features a linear CCD with 1024, 2048, or 4096 resolution with 10-μm square pixels, 512, 1024, or 2048 resolution with 14-µm square pixels.
Dalsa (www.dalsa.com) also showed a Camera Link camera, the Dalstar 1M75SA CMOS area camera, an addition to its Stop Action (SA) family. The camera features 1M-pixel resolution and a 75-frame/s rate. Like the 1M28-SA released earlier this year, the 1M75 features a Linlog sensor that increases intrascene dynamic range up to 120 dB.
IO Industries (www.ioindustries.com/index.asp) also announced support for Dalsa's P2-42-8k camera with its DVR Express camera interface board.
