使用许多USB网络摄像头的含义 [英] Implications of using many USB web cameras

问题描述

我正在考虑将多个低分辨率USB网络摄像头连接到单台计算机.这可能会对性能产生什么影响?例如，四个320x240摄像机相对于单个640x480摄像机如何表现?我对USB接口的体系结构不太熟悉，请注意性能方面的哪些方面?通过性能，我的意思是与单个摄像机相比，它将如何影响从多个摄像机读取图像数据的时间.

I'm looking into connecting multiple low resolution USB webcams to a single computer. What implications might this have on performance? How does, for example, four 320x240 cameras fare against a single 640x480 camera? I'm not well versed in the architecture of the USB interface, what are the performance caveats? By performance I mean how would it affect the time to read the image data from multiple cameras compared to a single one.

推荐答案

每个摄像头都连接到不同的USB端口吗?如果是这样，那很好.

Each webcam is connected to a different USB port? If so, its good.

即使只有1个端口连接了4个网络摄像头.我认为4 320x240也不会有任何问题. USB 2.0 = 320Mbps .流式传输320x240视频的速度不会超过1mbps.最坏的情况是，将320x240的分辨率设置为2mbps + 1mb其他数据. USB端口和设备之间的带宽为12mbps.

Even if its just 1 port with 4 connected webcams. I dont think 4 320x240 will have any problem either. USB 2.0 = 320Mbps. Streaming a 320x240 video wouldn't be over 1mbps. Worst case scenario, putting a 320x240 at 2mbps + 1mb of other data. That would be 12mbps bandwidth between your usb port and the device.

因此，从上面看，1个USB端口可以处理通过分离器连接的4个网络摄像头，就像1 640x480网络摄像头一样.

So from the above, the 1 USB port can handle 4 webcams connected by a splitter just as fast as 1 640x480 webcam.,

处理这些图像取决于您的计算机速度和算法编写方式.

Processing these images depends on your computer speed and how you write your algorithm.
