Hi,
I am using the snapshot function to acquire images. I am using a USB webcam to acquire the images.
Acquire single image frame from a webcam - MATLAB snapshot (mathworks.com)
Unfortunately, the snapshot function appears to operate slower than desired.
For the code below, I get approximately 64 milliseconds for each snapshot which translates to a frame rate of approximately 16.
clear
IntCam = webcam("Webcam C170");
f = @()SnapShot(IntCam);
t = timeit(f)
Seconds = 1;
FrameRate = Seconds/t
function img = SnapShot(RaspCam)
img = snapshot(RaspCam);
end
On the Matlab side of things, is there any implementation solutions that can speed up image acquisition via a webcam?
Thanks in advance for any suggestions
Regards
Cillian
