Detailed Description

Allows to grab images from a Basler camera using Pylon SDK. This is an abstract base class which can't be instantiated. Use vpPylonFactory functions to create class instances instead. Currently only GigE and USB3 cameras are supported.

To get a vpPylonGrabber, use the following code.

To use this class install first Pylon SDK
https://www.baslerweb.com/en/support/downloads/software-downloads/#type=pylonsoftware;version=all
Installation instructions included.

Once installed, configure ViSP using cmake to detect Pylon SDK and build ViSP to include Pylon SDK support.

This class was tested under Ubuntu with pylon 5.0.9 and the following cameras:

  • acA640-90gm
  • acA1600-60gm

This class is inspired by vpFlyCaptureGrabber with much simplified methods.

Examples:
testPylonGrabber.cpp, and tutorial-grabber-basler-pylon.cpp.
