Hi Everyone I am trying to make a camera come up and live stream images using openCV and the GenICam API for the drivers rather than one from the manufacturer. Does anyone know the proper way to use the GenICam API in C++ to pull up the camera as well as implement some basic features like gain?

Any help would be appreciated!

  • Your question seems very vague... you want a camera (which camera?) to *"come up"* (from where?) using OpenCV and GenICam API (which?) drivers *"rather than the one from the manufacturer"* (huh? isn't GenICam the manufacturer? if not which cameras do you mean?). Then you want to *"live stream"* (what? to where? how?) and *"pull something up from somewhere"*? – Mark Setchell Jul 14 '17 at 21:47
  • I am sorry, allow me to elaborate, I am using a Basler camera and rather than using the downloadable SDK from them I am trying to make a program that can use any GenICam camera rather than just Basler cameras. This program should be able to open a window and grab video off of the camera, but I do not know how to properly implement the GenICam API to have my program and openCV code communicate with the camera. I am also using Visual Studio 2012 as my compiler. – David Rosenfield Jul 14 '17 at 21:54
  • What camera? I'd avoid using OpenCV `VideoCapture` for any kind of production code. – Dan Mašek Jul 14 '17 at 23:35
  • Why is it best to avoid Video Capture? @DanMašek – David Rosenfield Jul 17 '17 at 13:24
  • Several of the backends for industrial cameras are quite limited in the extent you can control the cameras, and only work in polling mode. Check [the code](https://github.com/opencv/opencv/tree/master/modules/videoio/src) to see for yourself. You also need to build OpenCV yourself and enable the specific drivers (and have the appropriate third party libraries). – Dan Mašek Jul 17 '17 at 14:47
  • So to be clear with Opencv I would need a library for each brand of camera, could I implement the Genicam API to get around that? Also what is polling mode? – David Rosenfield Jul 17 '17 at 14:59
  • @DanMašek I forgot to reference you in my last comment – David Rosenfield Jul 17 '17 at 15:22
