I want to create a Matlab script which takes images and plots a graph of image intensity versus position.
Currently created a script like this:
%Create video input object
vid = videoinput('winvideo',1,'RGB24_640x480');
% Set video input object properties for this application.
% Note that example uses both SET method and dot notation method.
vid.TriggerRepeat = Inf;
vid.FramesPerTrigger = 3;
%vid.FrameGrabInterval = 5;
vid.ReturnedColorSpace = 'grayscale';
%vid.TimerPeriod = 1;
triggerconfig(vid, 'manual')
%vid.TimerFcn = 'trigger(vid)';
%preview(vid);
% Set value of a video source object property.
vid_src = getselectedsource(vid);
vid_src.Tag = 'Gaussian Beam';
get(vid_src);
% Create a figure window.
figure;
% Start acquiring frames.
start(vid);
for m=1:20
trigger(vid);
data_test1 = getdata(vid);
data_test3 = data_test1(:,:,1,1)
size_dt3 = size(data_test3)
yvalues = 1:size_dt3(1,1);
xvalues = 1:size_dt3(1,2);
dt3_columns = sum(data_test3,1);
dt3_rows = sum(data_test3,2);
subplot(2,2,1);
plot(xvalues,dt3_columns);
subplot(2,2,2);
plot(yvalues,dt3_rows);
end
stop(vid)
Which isn't working - says something about not having enough memory. Can anyone offer any help please?
