Quality control enhancement


National Instruments has released NI Vision 8 Development Module, a suite of vision software tools that engineers, integrators, and machine builders can use to improve system efficiency by increasing quality control in manufacturing. Vision 8 (V8) combines a collection of vision libraries with acquisition software for thousands of cameras, including those based on the IEEE 1394 (FireWire) connection standard, all optimized for common programming environments like NI LabView and Microsoft C++, Visual Basic and Microsoft.Net. Designed for engineers to identify packaging and assembly errors earlier in production, V8 includes new algorithms for: golden template comparison; optical character verification (OCV), and data matrix grading.

Algorithms for golden template comparison and OCV inspection identify flaws in labels and defects in products, while the data-matrix grading tool verifies that 2D bar codes are applied correctly in accordance to the ISO 16022 (AIM) standard.


Along with the hundreds of image processing and machine vision functions in the Vision 8 Development Module, engineers can use included software such as NI Vision Assistant and NI Vision Acquisition software. NI Vision Assistant is an image processing and application prototyping environment that automatically generates ready-to-run LabView diagrams or LabWindows/CVI, C/C++ or Visual Basic code.


NI Vision Acquisition software offers a set of drivers and utilities for acquiring, displaying and saving images from any NI frame grabber or camera based on the FireWire connection standard. For engineers and scientists who visualize and save images instead of process them, NI Vision Acquisition software is also available separate of the NI Vision Development Module.
