I found another issue - "Rolling Shutter" - The normal CMOS USB Webcams
do have rolling shutters. Looking out in the front is okay. Looking 90° 
left or right produces strange images for e.g. street lamps which seem
to bend towards driving direction.

So i am again puzzled on how to proceed. Using CCD industrial cameras
would be an option. But high-res, high shutter speed, CCD cams are
prohibitive expensive for a hobbiist when you need like 5-6 cameras
to get a 360° view.

So - CCD, Color, Global Shutter, FullHD, 30fps, Ethernet cameras
on my wishlist :)
