Finding green/pink flags

[Kingofl337]

Try this,
1. Log into the camera
2. Goto Advanced Settings and set White Balance to Hold
3. Goto Settings and turn down the brightness 20% of what it's set too
4. Goto Live video settings and take a screen shot (Alt + Print Screen)
5. Open MSPaint and Paste in the Picture, save as a JPG
6. Open Labview Vision Assistant, Open the file, and
7. Select Color, then Color Threshold, and then Color Model:HSL
8. Play with the Hue, Sat, Lum levels until most of the target is high lighted red
9. Set the new levels by updating tdata parameters, here is the list, these worked for me. You only need to set the values you changed in Vision Assistant.
//tdata.hue.minValue = 60;
//tdata.hue.maxValue = 80;
//tdata.saturation.minValue = 34;
//tdata.saturation.maxValue = 200;
//tdata.luminance.minValue = 128;
//tdata.luminance.maxValue = 240;


Edit: Also, it's a really good idea to start with the simple tracker demo 100% unmodified. Then you can tell if it's you or the camera values.

My friends and I are trying to get the Axis Camera to find the green/pink flags, but we are having a problem getting the camera to recognize anything and it didn't say it failed to recognize the camera, so what could help make it work?

The camera is just not working all together, but it is connected and on so we are in a jam. any Ideas?

Did you run the Camera Configuration Utility? Are you using the orange CAT-5 cable? Are you using the example? Does it work connected to your PC?

There will be example code posted soon that will do the detection of the two color targets. The code will be able to differentiate between the red and blue alliances.

Alright thanks very much for the help

[fordchrist675]

Actually it is still not working we used the CAT-5 and still are getting no feedback.

So the programmer and I are at a loss. also the utility isn't working so any ideas what to do?

Hey all-

I'm running WindRiver, and I'm running the SimpleTracker example code. I've used the NI Vision Assistant to get color values for my green vision target, and put those into the WindRiver code.

        tdata = GetTrackingData(GREEN, FLUORESCENT);
        tdata.luminance.maxValue = 187;
        tdata.luminance.minValue = 103;
        tdata.hue.minValue = 71;
        tdata.hue.maxValue = 98;
        tdata.saturation.minValue = 56;
        tdata.saturation.maxValue = 111;

I'm getting terminal feedback from the CRIO (finally...but that's another story), but the camera is failing to find any blobs matching the numbers that were obtained using the Vision Assistant.

Help, please?

Have you updated all the firmware? Are you using all the most current software?
