Image Acquisition Toolbox w/ Point Grey Flea3

Has anyone had success getting the MATLAB Image Acquisition Toolbox talking with Point Grey's USB 3.0 Flea3? I have tried Point Grey's latest camera drivers and SDK (Fly Capture 2) on my Windows 7 x64 machine, as well as some generic Window's drivers. So far, Windows only recognizes the camera when I have Point Grey's latest camera drivers installed. Any ideas on how to get this camera working with MATLAB friendly drivers?

Thanks for any suggestions!

A registration process is required through the Point Grey software to use the DirectShow dll's. This process is described here:

rob--

can you please confirm that you got a point grey USB3 camera to work with matlab. if so, was it 32 or 64-bit matlab? and 32- or 64-bit flycapture driver from ptgrey?

it's not working for me with 64-bit everything, so the more details you can provide the better. specifically, matlab 2012b on windows 7-SP1 crashes when all i do is

>> imaqhwinfo('pointgrey')

ans =

AdaptorDllName: [1x82 char]
AdaptorDllVersion: '4.4 (R2012b)'
AdaptorName: 'pointgrey'
DeviceIDs: {[1]}
DeviceInfo: [1x1 struct]

>> vid=videoinput('pointgrey',1); % crash here

everything works fine though in flycapture2.3.3.18.

thanks,

ben

Hello Ben,

This is a tricky one.

I do not believe that the Image Acquisition Toolbox and MATLAB 2012b directly support Point Grey USB 3 cameras. The release notes for this version of the Toolbox indicate that USB 2 cameras are now supported with the 'pointgrey' driver you're attempting to use.

http://www.mathworks.com/help/imaq/release-notes.html

Point Grey cameras will function with DirectShow drivers, and the Image Acquisition Toolbox can then communicate with the camera using the 'winvideo' driver. This only provides limited access to camera functionality from within MATLAB.

To gain full camera functionality from within MATLAB for Point Grey USB 3 cameras I was forced to write a custom video adapter. This process is described here:

http://www.mathworks.com/help/pdf_doc/imaq/adaptorkit.pdf

Hopefully USB 3 drivers will be supported soon!

An update to my previous post -

I 'accidentally' ran MATLAB 2012b without my custom Flea3 adapter installed. To my surprise, the Image Acquisition Toolbox did communicate with my Point Grey Flea3 USB3 cameras. I have not verified full functionality of the camera through the Toolbox, but it would appear as though the new 'pointgrey' video adapter in 2012b does (although not officially) support the Flea3 USB3 camera. I am running Windows 7 x64.

To make this work I did have to unregister the DirectShow DLLs using Point Grey's FlyCap2. There was a conflict between the DirectShow DLLs and MATLABs new 'pointgrey' driver that prevented MATLAB from accessing the camera.

Hi Rob,

Can you please share your 'custom adapter' ?

I tried DirectShow 'winvideo' driver to use FLEA3 USB, but the DirectShow driver only works in slow frame rate..

Hello Ben,

It is difficult for me to share software, especially if it is leaving North America, due to corporate restrictions. Let's chat directly and discuss our options. How can I get a hold of you?

Thanks,
Rob
