NI Vision Development Module allows machine designers to more efficiently enhance images, check for presence, locate features, identify objects and measure parts.
National Instruments has released the newest version of the NI Vision Development Module, a comprehensive library of image processing and machine vision functions for multiple programming languages, including NI LabView and LabWindows/CVI as well as Microsoft C, C++, Visual Basic and .NET.
With improved edge-detection algorithms available in the Vision Development Module 8.5, engineers can successfully locate hard-to-find edges like those in many web-inspection applications.
Users can also reliably find edges at 1/25 or better pixel accuracy and receive improved reliability in images with noise.
Engineers can detect straight-edged lines in images, which helps them detect multiple intersecting lines that appear in the image at different orientations.
The edge detector also provides support for calibrated images and incorporates calibration information, including image distortion associated with the image as part of the edge-detection process.
The Vision Development Module 8.5 provides enhanced support for the entire NI vision hardware platform and offers improved 2-D code recognition.
2D bar codes are currently the most common application for machine vision in industrial applications, and the Vision Development Module allows for 1D and 2D code reading and optical character recognition/verification on images.
This capability helps engineers identify packaging and assembly errors earlier in production.
Additional support for new bar code types has been added, including quick response (QR) code, 2D bar code that contains information about products, and Pharmacode, often used in the pharmaceutical industry.
The module also includes the Vision Assistant Express VI and the Vision Acquisition Express VI.
The Vision Assistant Express VI packages the power of the Vision Assistant, an image processing and application prototyping environment, into a single VI to simplify vision applications.
With Vision Acquisition Express VI engineers can acquire images from any NI vision hardware, as well as IEEE1394 and Gigabit Ethernet cameras connected to standard ports, all in a simple menu-driven environment.
Implementing the Vision Assistant Express VIs and the Vision Acquisition Express VIs increases the ease of use for programmable machine vision applications, cuts development time and lowers the bar of entry for machine designers who require the flexibility of LabView.
