I'm currently using a GigE camera using a pleora PT1000 IP engine with Matlab 2012a. I've successfuly been able to grab and display images as a realtime video with Matlab's image acquistion toolbox. However, I'm running into a timeout error when I use my code. It's not predictable since the amount of time it took for the error to occur went from anywhere between 9 seconds to 7 minutes with no apparent pattern. When I get the error, all I do is imaqreset and then run the code again to display video until I get the error again. My code is shown below. If anyone has has an idea as to what is going on, help would greatly be appreciated. Thank you.
%Camera setup
vid = videoinput('gige',1,'Mono16'); src = getselectedsource(vid); vid.FramesPerTrigger = inf; vid.FrameGrabInterval = 3; src.PacketSize = '9014'; start(vid);
%image setup
h = imagesc(zeros(480,640)); axis image; axis off;
%Load .mat files of processRAW parameters
load 'gain.mat'; load 'bias.mat'; load 'r.mat'; load 'badmap.mat'; load 'bbimages.mat'; load 't.mat';

while 1,
if imaqmem('FrameMemoryUsed') < 100000000
imaqmem
try
liveFeed = getsnapshot(vid);
catch
toc
return;
end
[S rawData] = processRAW(liveFeed,gain,bias,r,badmap,bbimages);
R = single(S(:,:,1));
R(R<280)=275;
R(R>300)=285;
try
set(h,'cdata',R);
drawnow;
catch
break;
end
else
flushdata(vid);
liveFeed = getsnapshot(vid);
[S rawData] = processRAW(liveFeed,gain,bias,r,badmap,bbimages);
R = single(S(:,:,1));
R(R<280)=275;
R(R>300)=285;
set(h,'cdata',R);
drawnow;
end
end
%Reset camera
flushdata(vid); stop(vid); delete(vid); imaqreset;
