The Transputer Systems Group at SI, Oslo, Norway has recently developed a new building block for industrial vision systems. "LINKEYE" an INTERFACE FOR LINE-SCAN CAMERAS This piece of hardware digitises the signal from a line-scan camera and multiplexes it line by line onto a number of transputer-links. This means that any network of transputers can be utilized at the link end of the interface. The multiplexer will work on any number from 1 to 16 links. At maximum the interface will handle 800Kpixels/s on each link (1.6Mpixels/s if Inmos ever will supply linkadapters with overlapped ack.). With 16 links this adds up to 12.8Mpixels/s performance if your algorithms and transputers are able to swallow the data. Linkeye has many features to support debugging, fault tolerance and general ease of use. Some of these are: - control of reset and various modes of the interface by the first transputer - event signalling of data overrun or new-line. - lots of LEDs on front panel indicating state of the interface - electronic aid for adjustment of aperture and focus - adjustable gain and offset on video signal Linkeye should be well suited for applications with hard real-time demands like industrial inspection and quality control systems. We have developed the board in cooperation with SIUs Vision Systems Group and they will use it in their ongoing developent of industrial inspection systems. We are interested in cooperating with- and making Linkeye available for interested companies and research institutes.
