问题描述
我想在一个Raspberry Pi上运行多个USB网络摄像头。我会把它们通过一个有源集线器。我希望网络摄像头同时拍摄静止图像（或者尽可能同时拍摄 - 或者两次延迟并不是什么大问题）并将图像保存到
a记忆棒中，每个图像的名称都会以相同的名称开始，然后才会显示。 cam1 ， cam2 ， cam3 etc。
来区分它们。
I want to have multiple USB webcams running on a single Raspberry Pi. I will put them through a powered hub. I want the webcams to take stills simultaneously (or as simultaneously as possible - a second or two delay isn't a big deal) and save the images to a memory stick, each image will have the same name beginning but then cam1, cam2, cam3 etc. to differentiate them from each other.
这可能吗？如果是这样，我限制使用的网络摄像机数量是多少？另外，我如何解决这些问题，可以 fswebcam 控制
多个网络摄像头？
Is this possible? If so, what number of webcams am I limited to? Also, how would I address them, can fswebcam control more than one webcam?
如果不可能，任何人都可以告诉我为什么不呢？
If it isn't possible, can anyone tell me why not?
