[GEM-dev] [OT] choice of camera for real time tracking people on a stage

[Jack]

Hello,

With the following configuration :
Ubuntu 16.04
Pd-0.47.0
GEM: ver: 0.93.git 60998f6

It's been a while since the topic of choosing a camera was not discussed
on the list.

Until today, for use in a theatre, i used the PS3 Eye camera and long
USB extensions (17 meters between computer and camera) and it was a
cheap and reliable solution.

But now, i need a faster camera with a higher resolution to get more
precision in the move detection. The camera will be at the zenith above
the stage.


I stayed on two possibilities :

- using USB3 industrial camera like this one :

- using an analog camera and a PCI (or USB) card to convert analog to
digital signal like this one :
https://www.blackmagicdesign.com/products/intensity (never tested but
recommended by Chris)


... and i stayed on problems with these both possibilities :

- USB3 industrial camera :
    - expensive
    - not easy to have a long distance between camera and computer
(maybe it is possible to convert USB3 cable <-> cat 7 ?)

- analog camera and PCI or USB card
    - low resolution
    - low framerate


Maybe things have changed ?
Can you tell me if there is new solutions in digital/analog capture with
a camera with a 'high' frame rate (120 fps minimum) and a 'high'
resolution (1920x1080 pixel minimum) working with Gem or via
v4l2loopback/GStreamer/Gem ?
Thanx a lot !
