Using 2 webcams with ODROID XU4

Unread postby Arc19 » Tue Mar 21, 2017 5:49 am

Hello all,

I am going to undertake a project that uses stereo vision, I was thinking of using the USB webcam suggested by odroid for this. My question is can 2 webcams be connected to the XU4 at the same time and used for image processing (open CV)

Thanks in advance.

Two webcams should be possible.
What is your target resolution and FPS?

To improve on the performances I was thinking of using a single frame as an image from 30fps video maybe at 640x480 resolution.

The camera I was going to use is the OCAM 720p webcam, I just want to verify if I can get two of them webacams and get the video from them both without an issue http://www.hardkernel.com/main/products ... 6883099080

The product description shows it working with opencv, will it work the same way if I connect two cameras and process two different images at once?

Thanks

640x480 at 30fps seems to be feasible with two webcams.
Two webcams should be assigned to /dev/video0 and /dev/video1.
