Vision sensors are getting more attention as industry searches for ways of speeding production. High-sensitivity measurement techniques take on sensor outputs in the microvolt range.

Coordinating cameras, controllers, frame grabbers, and output can be a challenge, especially for applications with multiple cameras.
The Compact Vision System from National Instruments, Austin, Tex., promises to simplify things. It melds powerful LabView software with low-cost, multicamera machine-vision systems. For instance, developers can connect a small, lightweight remote head camera for harsh industrial environments, a high-resolution megapixel camera for gauging small objects, and a low-cost monochrome camera for optical character recognition.
Three IEEE 1394 FireWire ports connect to a variety of imaging sensors including Sony and Basler cameras. Each camera shares a portion of the 400 Mbits/sec bandwidth. Developers choose camera resolution and speed to match the application. Compact Vision is compatible with NI Vision Builder Automated Inspection software that builds inspection systems with a point-and-click interface. LabView handles more customized applications.
The system includes 15 digital inputs, 14 digital outputs, RS-232, and Ethernet connections. More than 20 NI FieldPoint distributed I/O measurement modules can interface with PLCs and motion controllers.
The CVS-145x Series vision system from National Instruments sports three FireWire camera inputs for handling a variety of machine-vision tasks.
