Vision Decisions

[sarah_storer]

To me, the aspect of vision in the game doesn't seem as detrimental as in years past. What is your team doing in terms of vision?

and if vision does in fact play a key role in the game this year, do you know of any comprehensive vision how-to guides that I could look at? Our team is a vision rookie!

Thank you

Don't know much I could tell you in terms of how to use vision right now, but remember: some people will be scoring totes 4-6 high, and when that happens you are making a wall that you can't see through and your bot may have to go behind.

True, I didn't think of having to go behind stacks of totes.

As for autonomous, how key do you think vision will be in the competition?

I believe that in auton it will only be useful for tracking the creates when attempting to stack them. Besides that I can't think of it being useful for much except in tele-op when your robot goes behind a stack of crates. Then the camera could be useful. Best of luck with it though. The example for labview is already broken.

The issue with the LV examples is that the initial path location doesn't point to the Sample Images folder, but points to a subfolder. Please delete the last two path segments before running, or change the folder to point to other images first.

It should also work fine with a camera, which was how most of the testing was done. Please post if you have questions or find other issues.

Detecting the vision targets is very easy, doing something with that information rather hard. I usually recommend that it's the very last thing to worry about, since actually doing anything with requires all the code to be able to maneuver and stack properly in the first place.

I tried running this just for fun using my spare MS HD-3000. The error message about missing file(s) still continues to pop up. So, when you say,
Please delete the last two path segments before running, or change the folder to point to other images first., exactly where is this edit/deletion supposed to take place?
Sorry, my basic approach to doing this modification didn't yield any results.

OK, I answered my own question.

Open the example project. Launch any one of the three example vi's. On the Files tab, browse to the folder that actually has the sample images.

Now you can RUN it with either a sample image, or a web cam.

You got it. There were initially way more photos when the example was written. At the last minute, the photos were simplified and the path didn't get updated. So either select the path text and delete the last two directory names, or use the button to browse to the example photos location.

Once you get to that folder what do you do. Delete it or repair the pathway?

Once you browse to the folder, in my case it was,
C:\Program Files (x86)\National Instruments\LabVIEW 2014\examples\FRC\roboRIO\Vision\2015 Vision Example\Sample Images
then just click Select Folder. That's it.

I think I get it now. I'll try it later today. Thanks for the help!
