Multiple identical cameras in MATLAB
in [Matlab]
|
From: Stefania Cristina on 15 May 2010 11:13 I am implementing a multiple camera setup for a machine vision application, and am writing my code in MATLAB. I am presently using four identical (and expensive) uEye cameras, and am triggering them from MATLAB. Since these cameras are identical, I am giving them a different Device ID from their SDK software, so that MATLAB would recognize them as four separate cameras (as opposed to MATLAB recognizing only a single camera when I do not change their Device IDs). However, I intend to change these cameras to simple, cheap and identical webcams in order to lower the cost of my system. In the case of the webcams, the SDK software will not be available. In addition, there might by the problem of only a single webcam being recognized in MATLAB since all the webcams are identical. Does anyone have any experience with such a situation, and is anyone knowledgeable of its solution please? Thanks in advance, Stefania.

Hi Stefania, Identical cameras should show up with different device ID's. Mark
