显示 更早的评论
Hi everyone, I want to extract the frame from my running webcam every 3 second I want to extract the frame and save it into variable to process it later so how I can do it please ?? I did this but not taking picture as running video ..
vid = videoinput('winvideo',2);
set(vid, 'FramesPerTrigger', Inf);
set(vid, 'ReturnedColorspace', 'rgb');
for i=1:10
data = getsnapshot(vid);
figure(i);
imshow(data);
end

You are not saving the individual images.
One easy way is to use a cell array:
for i=1:10
data{i} = snapshot(vid);
figure(i);
imshow(data{i});
end
I do not have the Image Acquisition Toolbox, only the Support Package for USB Webcams. This loop worked for me with it.

My pleasure.
See the Image Processing Toolbox immovie (link) function for one approach. Also see the links in and at the end of the page for that documentation.

Khaled Al-Faleh: To save simultaneous picture use the function num2str(obj).
