Trends in low-end machine vision
At a recent press conference held at Omron Electronics Inc. (Schaumburg, IL; www.omron.com), vision-product marketing specialist Mark Sippel offered some views on trends in low-end machine-vision systems.
He covered high- and low-end machine-vision system definitions, where low-end machine-vision systems are being used, and present and future low-end machine-vision system trends.
According to Sippel, high-end machine-vision systems are typically open PC-based. They offer more functionality and flexibility, a filled PC chassis, a frame-grabber board, one or more cameras, expandable hardware and software, and costs exceeding $12,000. On the other hand, low-end machine-vision systems are typically proprietary microprocessor-based. They provide limited but growing functionality, generally a closed architecture, a local or remote self-contained camera and controller, easy menu-driven setup and use, and cost from $1000 to $8000.
In the 1999 North American general-purpose machine-vision market, Sippel listed the total sales percentages for high-end systems at $192 million or 95% market share and low-end systems at $11 million or 5% market share. For the same market, on an estimated 15,902 total units sold, high-end systems achieved 79% and low-end systems trailed at 21%.
High-end machine-vision systems are usually positioned at the end of the assembly line, says Sippel. They are used for the vision inspection of products after value has been added and just prior to final packaging. In contrast, low-end machine-vision systems are placed at several locations along the assembly line to inspect products as value is being added.
Sippel foresees new markets for low-end machine-vision systems for several reasons. Because they offer lower cost, these low-end systems allow wider scalability, affordable off-line applications, increasing functionality for more applications, compact size for flexible installations, and little maintenance and programming for low-skill operators.
As for low-end machine-vision system trends, Sippel anticipates continued lower cost and further optimization in ease of use, such as menu operation, no programming needed, and keypad setup. Although system size will undergo even further reduction, lighting and lenses will be integrated and input/output connections will be built in. Low-end systems are benefiting from the migration of tools from high-end systems and from expanded communications capabilities. Advanced features expected include two-camera operation, color vision, and Windows-based software adoption. System connectivity should expand with couplings to image monitors, photosensors, programmable logic controllers, personal computers, and local networks.
