

LabVIEW
NI Vision Acquisition Software
NI Vision Development Module
(NI Vision Builder for Automated Inspection)

These software packages will be explained in detailed later.
In the examples we will use a GigE Vision camera (Basler scA640-70gc), i.e. the camera is connected to the computer using a standard Ethernet cable.
