National Instruments Application Software

This section describes the National Instruments application software 
packages you can use to analyze and process the images you acquire 
with the NI 1405.

Vision Builder for Automated Inspection

NI Vision Builder for Automated Inspection (AI) is configurable machine 
vision software that you can use to prototype, benchmark, and deploy 
applications for use in LabVIEW, LabWindows/CVI, and Measurement 
Studio. Vision Builder AI does not require programming, but it is scalable 
to powerful programming environments.

Vision Builder AI allows you to easily configure and benchmark a 
sequence of visual inspection steps, as well as deploy the visual inspection 
system for automated inspection. With Vision Builder AI, you can perform 
powerful visual inspection tasks and make decisions based on the results of 
individual tasks. With Vision Builder AI, you can migrate the configured 
inspection to LabVIEW, extending the capabilities of your applications if 
necessary.

Vision Development Module

The Vision Development Module is an image acquisition, processing, and 
analysis library of more than 270 functions for common machine vision 
tasks, such as: 

Pattern matching

Particle analysis

Gauging

Taking measurements

Grayscale, color, and binary image display

You can use the Vision Development Module functions individually or in 
combination. With the Vision Development Module, you can acquire, 
display, and store images, as well as perform image analysis and 
processing. Using the Vision Development Module, imaging novices and 
experts can program the most basic or complicated image applications 
without knowledge of particular algorithm implementations.
