Smart camera reads barcodes

Click here to enlarge image

Quadrus EZ smart camera combines a vision system and a laser scanner for decoding both linear barcodes and 2-D symbologies. Using patented technology, the field-of-view locator allows the user to align the reader to the symbol without the use of video monitors or a PC. After alignment, the user pushes the EZ button and the camera automatically calibrates on the symbol and can decode 60 codes/s. Video input/output and USB and Ethernet connections are included.

NomadFIRE carrier board is a complete system board with video-capture capabilities. It serves as a rapid-prototyping platform for embedded imaging applications and provides three FireWire video ports for video data transmissions to 400 Mbits/s. A PCI-104-compliant connector provides PCI expansion to connect third-party image-acquisition and processing cards. LCD (CMOS and LVDS) and CRT interfaces offer connectivity to TFT LCD display panels and plug-n-play monitors, respectively. A CompactFlash Type II socket connects to removable solid-state storage devices for software upgrades and system recovery. Plug-N-Run module and a carrier board yield a portable embedded image processing system, capable of capturing and manipulating high-resolution images.
