Axis cam problem

Doesn't the computer have to have it's IP settings set to 10.xx.yy.6 (where xx is the first two digits of your team number and yy is the last two digits of your team number) in order to connect to the cRIO?

So far... Our computer has been able to directly connect via Xover cable to the camera where we can test the live feed stuff in the browser, run the Setup Axis Camera and stream but not acquire and save pictures via NI Vision Assistant. Problem is... None of this happens if the camera is connected to the cRIO through ePort 2.

The second thing I want to ask is... Are we supposed to use NI Vision Assistant to handle the camera finding and tracking of colors and/or shapes? If so, how do we implement this and later change this into working C/C++ code (we're using WindRiver). If not, what programs are we supposed to use to control our camera functions?

The stuff I said in my previous post is assuming the camera is plugged into your computer. I have no idea how to get images from the robot without LabView. That said, your robot can't use it if its not plugged into the cRIO.

Your computer will not be able to gather images from the camera if the camera in plugged into the cRIO. If it is plugged into the cRIO, you can only get the images via LabView or however C/C++ does it. To get images on the computer, the camera must be plugged into the computer (as the network stuff on the robot blocks the small server included in the camera).

Vision Assistant takes a bit of getting used to (not as much as LabView, but just a bit). What I would do if you are unfamiliar with it is to start playing with any old image, then playing with Line Profile and Color Threshold. I know there is a LabView export function, but I cannot recall if there is a C/C++ export function (look in the Tools menu item).
