It seems like the issue is with the identical names of USB cameras connected. You can rename the USB webcams by following below steps.
Here is the instance where I have a test device and USB Video device and I am changing the names and passing them back to the “webcamlist” function so that it’ll assign new names to the usb drivers. Then pass those values to the Image Acquisition Toolbox.
>> webcamlist %gets the device names of web cams connected to the pc
ans = 2×1 cell array
{'USB Video Device'}
{'Webcam Test Device'}
Renaming the 1stdevice
>> webcamlist{1} = 'sony'
webcamlist =
1×1 cell array
{'sony'}
Renaming the 2nddevice
>> webcamlist{2} = 'nikon'
webcamlist =
1×2 cell array
{'sony'} {'nikon'}
Final Camera Devices list will be then:
>> webcamlist %reassigned values
webcamlist =
1×2 cell array
{'sony'} {'nikon'}
Now, since the names are changed, MATLAB will take them as two different variables and won’t override.
