Issue Details

  • I am interested in the capabilities of NI Vision software but I am unsure which product I should use.
  • I have a valid license for NI Vision Software but I am unclear about the differences between NI Vision Acquisition Software (VAS), NI Vision Builder (VBAI) and NI Vision Development Module (VDM). 


Vision Acquisition Software (VAS) 

  • Description: The Vision Acquisition Software (VAS) is a set of drivers and utilities used to acquire, display, and save images from a wide range of camera types, including cameras using GigE Vision, IEEE 1394 (FireWire), USB 2.0, USB 3 Vision, or the Camera Link standard.
  • Included In: VAS is included in both VDM and VBAI
  • Components: VAS is made up of the following three drivers. See here for more information about these drivers
    • ​NI-IMAQ - acquisition from NI frame grabbers, as well as general display, file saving and acquisition functions
    • NI-IMAQdx - acquisition from GigE Vision, IEEE-1394 cameras, USB cameras that are DirectShow compliant (VAS 2009 onwards), and some IP cameras.
    • NI-IMAQ I/O - configuration of FPGA included in the PCI-8254R, PCI-8255R, Compact Vision System
  • Usage: The drivers included with NI Vision Acquisition Software (VAS) allow you to acquire, display, and save images from a wide range of cameras. However, only the NI VDM and NI VBAI software packages include built-in support for advanced image processing and analysis. Note that a license for VAS is included with all NI Frame Grabbers .

Vision Development Module (VDM) 

  • Description: Vision Development Module (VDM) provides machine vision and image processing functions for LabVIEW, C/C++, Visual Basic, and .NET environments 
  • Included In: VDM is a separately licensed module installed into LabVIEW
  • Components: VDM includes the Vision Assistant tool, a prototyping and code generation tool similar to NI Vision Builder in its menu-driven interface. Vision Assistant is a useful tool for developing and testing a series of image analysis and processing steps from which code can be generated.
  • Usage: In general, VDM functions are used for image processing and analysis. Some example uses include: pattern matching, particle analysis, edge detection, thresholding, histograms, and optical character recognition.The Vision Development Module is supported on Windows and LabVIEW Real-Time. This means you can use VDM on remote targets such as the NI CVS (Compact Vision System) or an NI Smart Camera. 

Vision Builder for Automated Inspection (VBAI) 

  • Description: The Vision Builder for Automated Inspection (VBAI) is a stand-alone, configurable machine vision development environment that requires no programming knowledge to configure.
  • Components: VBAI includes over 100 commonly used vision development tools including pattern matching, optical character recognition, and particle analysis. It also installs VAS for acquiring images from the camera.
  • Usage: VBAI can run image processing inspections on remote targets, including real-time controllers and FPGAs, and can be used to configure those environments.

Additional Information

You will need either VAS and VDM if you are working in LabVIEW, or VAS and VBAI if you would like to use a more configuration-based environment. You will also need VAS software to communicate with your camera and acquire images, and processing software (either VDM or VBAI) to process the images received.
