For this year's game, is it very hard to get the vision process to work? We have never used vision process before, just want to know if it takes too much time to do. Also, if it is doable, where could we find the tutorial?

2. Teams using LabView for programming may find that the robot main application already contains some software that does this. Check it out. |

Re: How hard is it to do the vision process?
You have to start sometime. If you can afford to dedicated 2 programmers to the task, you could figure it out.
Note: Learn how to launch a thread/process. You won't be able to get it to work inside your main code (takes too long). It is best to run it as a parallel process. Main process sends a request, and looks for the vision process to set a value. |

Re: How hard is it to do the vision process?
As mentioned, the default LV code has a camera server for USB. This isn't needed for the Axis, so both of those will work for dashboard display and/or dashboard processing. Robot code contains a camera acquisition loop that is disabled until you turn on a global and add the processing.
The Getting Started window of LabVIEW has a tab on the left for Tutorials. One of them, eight or nine, is about vision and ways to integrate it into either the robot loop or into the dashboard. There are other good ways to do the processing, but this should get you pretty far down the path. Ask questions in this thread if you have issues. Greg McKaskle |

Re: How hard is it to do the vision process?
In that case, I'd look at the Screensteps Live tutorials on vision processing in Java.
Of course, you can also send the images to the dashboard and use a different language. Good luck. Greg McKaskle |

Re: How hard is it to do the vision process?
Can someone comment on how hard is it to create a script with the National Instruments Vision Assistant and then incorporate it into a Java RIO program?
The Vision Assistant is a user-friendly way of getting in to vision processing. Worth installing just to take a look. |

Thank you so much! We will look at the tutorials.

Re: How hard is it to do the vision process?
You may want to try out RoboRealm. We have had success with it in the past and use Java on our robot. It is included in the KoP and the code is in TIMS. Look at http://www.roborealm.com/FRC2016/index.php for tutorials/downloading. Good luck!
P.S. Please note in the future, that you can reply to multiple posts in one post--this makes it easier to read and get through posts. |
