Using USB webcams in Simulink

Hello all, I was looking for a solution for this but it seems as if nobody has this problem!

All I want is to connect a simple usb webcam to the pc and stream the video in Simulink. Why is that so hard to find??

Using Matlab r2014a, either Microsoft Lifecam Cinema or Logitech C920 webcam. I do not care for real-time data, just stream the video frame-by-frame in each simulation step. It is possible in matlab but could not find it in simulink.

Any suggestions?

Hello Tim,

The workflow to access a USB webcam in real-time with Simulink depends on the version of the product being used. For MATLAB version R2020a and earlier, this can be done using USB camera blocks, 'From USB Video Device'and 'USB Video Device List'. A step-by-step procedure is available in the documentation: https://www.mathworks.com/help/releases/R2020a/xpc/io_ref/usb-video-display-on-target-computer.html.
