Interface and control FLIR (BlackFly S) with Matlab 64-bit platform code

Hello Mathworks team,

This is a follow up on @Zoran Popovic's comment here: Does Image Acquisition Toolbox support FLIR (Point Grey) Blackfly S model camera?

Aim: To interface the BlackFly S camera (Model # BFS-U3-04S2M-CS) with Matlab such that I can control the camera through it.

I would like to try loading the Spinnaker drivers into Matlab and use the corresponding register read/write functions. Following are my questions:

1. I would like to know which DLL should I be adding following the procedure Loadlibrary function in Matlab

2. Once the DLL gets loaded, I would like to have the inbuilt register read/write functions list?

I am writing here as I have already tried contacting the FLIR Integrated Imaging Solutions Inc. (formerly known as Point Grey Research) technical support. The lady there informed me to contact Mathworks for further help on this issue.

I use the Spinnaker 64-bit DLL v140 (install the SDK using VS2015 setting) as recommended by the FLIR support team. In Matlab I use C++ compiler configured to:

MEX configured to use 'Microsoft Visual C++ 2015 Professional' for C++ language compilation.

The following is the code I tried:

function [rawfile] = acquireRawImg32Bit()

  loadlibrary('C:\Program Files\Point Grey Research\Spinnaker\bin\vs2015\SpinnakerC_v140.dll', 'C:\Program Files\Point Grey Research\Spinnaker\include\spinc\SpinnakerC.h')
  libfunctions('SpinnakerC_v140')

  hCam = libpointer('hCam', 'spinCamera');
  calllib('SpinnakerC_v140', 'spinCameraBeginAcquisition', hCam);

  unloadlibrary('SpinnakerC_v140');
end

After which I got a huge bunch of errors:

Warning: Warnings messages were produced while parsing.  Check the
functions you intend to use for correctness.  Warning text can be

Do not know how to resolve these errors, although I tried various recommended methods on stackoverflow as well as Mathworks forums. Please help as Mathworks team would know how to resolve this in a timely and efficient manner.

Had the same problem, solution for my case here: Does Image Acquisition Toolbox support FLIR (Point Grey) Blackfly S model camera?

Answer 1

[Andrei Ursache]

As of MATLAB R2018b, a custom adaptor for FLIR/PointGrey Spinnaker drivers is available for Image Acquisition Toolbox. Refer to instructions from the following File Exchange entry:

https://www.mathworks.com/matlabcentral/fileexchange/69202-flir-spinnaker-support-by-image-acquisition-toolbox

[az clearview]

My understanding is that this Answer does not address the request for camera control originally posed. It's functionality is that of the winvideo adapter, with no control of exposure, gain, etc.

Any input into how to address the compiling errors reported by original poster (@Harsha)?

Thanks! A
