Inaugural Vision Show East excels

Last month at the Hynes Convention Center in Boston, MA, nearly 100 exhibitors displayed their latest products, systems, and technologies for machine-vision applications to more than 2530 attendees at Vision Show East, the first major trade show and conference on the East Coast sponsored by the Automated Imaging Association (AIA; Ann Arbor, MI; The show was a huge success based on large daily crowds, packed booths, crammed sessions, and positive overall enthusiasm by both exhibitors and visitors.

Jeffrey Burnstein, AIA executive director, commented, "Many of the attendees have been unable to attend our annual Vision Show on the West Coast and were eager to attend a show closer to their company. As a result, this show drew a large percentage of end users and OEMs with immediate needs for machine vision, which should help stimulate new growth in the second half of this year."

The show also offered four tutorials and 11 conference sessions. The tutorials covered the fundamentals of machine vision; how to integrate machine vision, lighting and optics applications; and how to select machine-vision components. The sessions discussed PC-based vision developments and costs, robotic and web-inspection vision, color-processing methods, advances in digital cameras and image acquisition, label inspection, lighting and optics, and emerging machine-vision applications.

In the session "New Developments in PC-based Vision," Jerry Fife, product manager, visual imaging systems, Sony Electronics Inc. (Park Ridge, NJ), presented a short course in IEEE-1394, a high-performance serial bus known as FireWire for the bidirectional transfer of digital data at speeds to 400 Mbit/s. He emphasized the IEEE-1394 benefits of high speed and bandwidth, flexible networking, simplified cabling, and low cost.

Another speaker, Michelle Chaput, marketing communications manager, Imaging Technology Inc. (Bedford, MA), covered pattern-finding/search capabilities. She described how geometric-based search software precisely locates features despite degraded images, detects 360° angle changes, reports angle variances from the trained pattern, and provides distinct information about variations in images relative to the trained pattern.

Also, Faycal Benayad-Cherif, principal researcher, Intelligent Automation Systems Inc. (Cambridge, MA), spoke on improving inspection processes by combining 2- and 3-D vision techniques. He concluded that 2- and 3-D techniques complement each other for such applications as robotic guidance, metrology measurements, and parts inspection, but not all applications need both.

At "What's New in Digital Cameras and Image Acquisition," Nathaniel McCaffrey, head of the advanced imaging group, Sarnoff Corp. (Princeton, NJ), presented work on CMOS active pixel sensors with extended dynamic range. This effort uses standard CMOS process flows and scalable architectures, focuses on video rate imagers with film-like responses, and aims at producing low-cost ASIC digital cameras on a chip with wide dynamic range, low voltage and power, and short latency turn-on times.

Another speaker at this session, Karl Gunnarsson, vice president of Metolius Inc. (Woodinville, WA), talked about a smart single-chip CMOS camera that can simultaneously acquire images for gray-scale level, RGB color structure, laser scatter, and 3-D profile features. The 512 x 512-pixel chip also contains 512 analog-to-digital converters and 512 processing elements.

Joseph Sgro, chief executive officer, Alacron Inc. (Nashua, NH), offered some smart-camera-design considerations for machine-vision applications. He concluded that sensor technology developments, increasing bandwidth with processing capabilities, and faster input/output data rates will spur the machine-vision industry to consider smart cameras. Moreover, intelligent cameras have the potential to simplify and reduce the costs associated with installing a machine-vision platform, he said.

A programming-free smart camera called ZiCAM for inspection applications was described by Manish Shelat, product marketing manager, Pulnix America Inc. (Sunnyvale, CA). This camera implements zero instruction set computer and digital neural-network chip technologies for high-performance pattern recognition and classification. In addition to dynamic reconfigurable computing, it can make and validate decisions, needs no programming, simplifies feature extraction, and connects to Ethernet networks.

New products introduced

On the exhibitor floor, numerous vision products were introduced, especially lighting and optics devices, cameras, and frame grabbers, as well as boards, modules, and software tools. Attendees clogged the aisles for most of three days, and many exhibitors were overwhelmed with attendee quality, experience, and interest. Some exhibitors reported that visitors seeking immediate vision solutions were escorted back to company facilities for serious business discussions.
