Using NI-IMAQdx in LabVIEW

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.

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.

NI-IMAQdx adds a subpalette of VIs to the Vision and Motion Functions palette and an Image Display control to the Controls palette.

Create NI-IMAQdx applications as you would any other LabVIEW or LabVIEW Real-Time (RT) application. Place VIs onto the block diagram to create the program, and use the front panel to design the user interface. Click Run to compile and run the application.

Before you start building an image acquisition application, familiarize yourself with the basic knowledge and concepts contained in the following sections.
