Re: Human Vision Camera compatiable with FMS & Java ?

Its critical we have a reliable trustworthy camera feed going for champs.
What was your Microsoft LifeCam HD-3000 connected to, that connected it to the network, that interfaced with FMS?

Was it on a co-processor like the Kangaroo or something running Linux?

I totally agree with Greg as I see no reason to believe that a Microsoft LifeCam HD-3000 camera won't work with FMS.

I do see reasons why the Microsoft LifeCam HD-3000 camera might not work very easily with Linux in general. The RoboRIO runs a distribution of Linux so therefore there are issues I have seen and documented in another topic on ChiefDelphi between the Microsoft LifeCam HD-3000 and the RoboRIO. These issues very easily could be annoying to deal with when using Java on the RoboRIO even directly to Video4Linux. They are likely as bad if you use Java-to-OpenCV-to-Video4Linux or something like GRIP-to-Java-to-OpenCV-to-Video4Linux.

I also agree with Greg - Logitech makes a lot of similar and cheaper webcams that work just fine with the entire FIRST control package with the current distribution of Linux. The Logitech C920 USB camera works just fine to the default FIRST dashboard (you need a bit of Java code to get the RoboRIO to stream to the driver's station) and you can switch the camera that sends if you have multiple in Java I've tested it (there is a short delay). However, as a USB camera, the Logitech C920 doesn't work to a plain old web browser all by itself (you need to add more software to make that happen).

The Axis cameras are fine webcams and any model Greg also listed will do the job. Just be aware you may need to give it a static IP to get it working on a real field and that may make testing in the pit interesting. More than one Axis camera might also be a challenge.
