Stereo Vision DM6446 + USB WEBCAMS

Hi, 

 

I am planning to use stereo vision in dm6446.

I would like to know if anyone has ever done this while acquiring images from 2 webcams.

My question is, is it possible to connect 2 webcams via USB to the DM6446 and extract 320*240 images in real time?

Is there any problem with the USB bandwidth or something else for this case?

 

P.S. I am using the EVM6446

 

Best Regards

    We haven't tried this kind of application here @ TI, thus we are not sure whether your application is feasible, nor will we be able to support this. But basically, this boils down to how data is transferred to USB.

    You will need the following information:

    • how much overhead your USB webcam adds when it transfers data to DM6446
    • frame rate
    • bytes per pixel
    • is the packet on a per line basis or per frame.
    • how much overhead there is during "switching" and how often you need to switch between the two cameras (every frame), because there is only one USB port.
    • others that affect the effective throughput of the USB.
