Hello,

For R2020a and earlier, refer to this workflow documentation for a step-by-step guide to integrating a USB camera into your model using the USB camera blocks, "From USB Video Device" and "USB Video Device List":

https://www.mathworks.com/help/releases/R2020a/xpc/io_ref/usb-video-display-on-target-computer.html

For R2020b and later, connect the USB webcam to the development PC and stream the data to the target machine using the Simulink Real-Time UDP blocks, "UDP Send" and "UDP Receive". To learn more, please refer to the following documentation links:

• For more about "UDP Send":https://www.mathworks.com/help/releases/R2020b/slrealtime/io_ref/udpsend.html
• For more about "UDP Receive":https://www.mathworks.com/help/releases/R2020b/slrealtime/io_ref/udpreceive.html
• For an example about transmitting data via UDP:https://www.mathworks.com/help/releases/R2020b/slrealtime/ug/target-to-host-transmission-using-udp.html

Hope this helps!

Use the From Video Device block, which requires the Image Acquisition Toolbox.

You can see some examples here: https://www.mathworks.com/help/imaq/examples.html?category=image-acquisition-in-simulink-1

You will need to install the Image Acquisition Toolbox Support Package for OS Generic Video Interface using the Add-Ons explorer in order to connect to your webcam.
