I have not been able to find one that works with this camera and wanted to know if anyone has had success opening this type of camera.

TeleDyne Dalsa Linea uses GigE communication protocol.

you can try   cv::CAP_PVAPI

If it doesn't work I recommend using JAI SDK ~ you can download it here.

Hope it helps.

Hi, To be able to use this camera you have to download Sapera LT 8.12 SDK (or whatever version there is now). As this SDK for me was real pain to use I have used CVB libraries that I have got from my camera provider.

Anyway this is what I got from Teledyne support:

void * pBuffer;

pSaperaBuffer->GetAddress(pSaperaBuffer->GetIndex(), &pBuffer);

"pSaperaBuffer" is the SapBuffer that's used in every Sapera ++ demo.

With that you have the starting address of the Sapera Buffer and that should help you "cast" it to an OpenCV compliant buffer.

Should also work when pBuffer is of type UINT8 (if the Nano outputs 8bit) or UINT16.

Hope this helps - for more, please check the various SapMyProcessing.cpp versions in the Sapera demos\classes\vc samples,

I hope it will help you.

@PiMac can you elaborate on what is an openCV compliant buffer?

I suppose it means Mat or iplimage structure. I will try to give you an example but cant promise anything since I don't recall if I have managed it or not.

Thanks for clearing that up!!

No problem. I was trying to do sth with

Mat vMat = Mat(Buffers->GetHeight(), Buffers->GetWidth(), CV_8UC(Buffers->GetBytesPerPixel()));

But I don't have a working example so I must have given up when received CVB library. If you figure it out please post the solution if you can.
