Vision Processing - GRIP to LabView
 
Hello,
My team and I are currently working on vision processing for the 2017 SteamWorks competition. We are currently using GRIP in order to recognize the targets for the gear placement in the competition. We have a few questions.

1) We are trying to work with the network tables to use the data from our GRIP program in LabView. We are unsure about how network tables work and how to access them in LabView.

2) Do we connect the camera (Logitech)to the computer or to the RoboRio?

3) Do we connect the computer to the RoboRio via USB cable or Ethernet cable.

4) Do we connect the computer to the RoboRio or the radio?

5) How do we have a live feed of video separate from vision processing for our drivers? What setting do we use in order to not use too much bandwidth at competition?

hi,
If you're using LabVIEW, why not use the NI vision code instead of using GRIP? Look at the vision processing sample code. It'll get you most of the way there. The camera will be on the robot and all images will go to roboRIO (they can of course also be routed to the console so the user can see them) for processing.

If you insist on using GRIP, be sure to read the "New for 2017" section on screenstepslive https://wpilib.screenstepslive.com/s...8-new-for-2017

Regarding your other questions, I'm not sure what you're referring to when you say "computer" - is this the driver station or some other embedded processor?

With regards to using multiple cameras in LabVIEW, see some of the other threads on the forum.

Good luck

Seriously, Adam, plug the camera into the processor that's using it (the TK1.)
