问题描述:

How do I connect two webcams to a PC? I need to grab the frames from the two webcam inputs simultaneously. What software should I use and is there any extra hardware that I will need? I prefer connecting the cameras using USB as most computers have several of these ports. Also please suggest solutions that will work in Linux. I'm using Ubuntu 9.04.

网友答案:

Plug the first one in, then plug the second one in. Each will have its own /dev/videoX node that can be used for capture. Not sure if there's any prepackaged software for capture though; you might be able to find some ideas in ZoneMinder.

网友答案:

Just plug them in. The kernel will load the driver and create two video devices where you can grab the frames. They won't be in sync 100% so be ready to drop frames every now and then.
