Using NI-IMAQdx in LabVIEW
This chapter describes how to use NI-IMAQdx VIs in LabVIEW.
Introduction
The NI-IMAQdx VI library—part of the NI-IMAQdx software—is a group
of virtual instruments (VIs) that enable you to use LabVIEW with your
camera.
of virtual instruments (VIs) that enable you to use LabVIEW with your
camera.
NI Vision for LabVIEW is the National Instruments image processing and
analysis library, which consists of more than 400 VIs. Some of the basic
NI Vision VIs are shared with NI-IMAQdx. If you do not have NI Vision,
you can use the NI Vision VIs included with NI-IMAQdx to create an
image acquisition application. When you use these basic VIs, you can
upgrade your application later to use additional NI Vision VIs without
making changes to your initial image acquisition application.
