Re: Advice on first camera selection
Posted: 07 Nov 2017, 06:55
I have used the Panasonic GH4 (rolling shutter and reduced resolution) with an HDMI capture device.
I also have the PointGrey global shutter.
I don't notice any real difference.
With the PointGrey, I use the full resolution of the chip. At full resolution ( 2,048×1,536 ), I get faster scan time then with the Panasonic at FullHD, the transfer rate to the PC is better. If I lower the resolution on the PointGrey, It goes even faster.
Industrial cameras are easier to use with HP 3D (size & weight of camera, software control from the PC, transfer speed).
I don't think the global / rolling is a real issue. Most other users have rolling and their scans are great.
Not 100% sure if reducing resolution would not create distorsions (?)
