Hi there, I'm trying to connect to a usb camera plugged into the raspberry pi from my Pc using matlab. I can do this easily using the simulink block V4L2 Video Capture, although i need to this in a m file. Is there a function like cameraboard to connect to usb webcams ?

I appreciate some help. Best regards, Walter

在 MATLAB Online 中打开

To be complete...:

rpi = raspi();
camera=webcam(rpi);
imagesc(snapshot(camera));

One way you could try is to set the USB webcam up as a server and use the MATLAB Support for IP Cameras.

This may help:

There is also a MATLAB support package for USB Web cameras - http://www.mathworks.com/hardware-support/matlab-webcam.html

But I think the author of the question wants to access the USB Camera that is connected to the Raspberry Pi, not a USB Camera that is connected directly to the PC. I don't think the USB Support Package would work in this application.
