Not seeing MS Webcam images in default dashboard

[Greg McKaskle]

The green arrow, red square, and red circle are for recording the video and smart dashboard values to a log file for later review. Triangle plays a recorded video, circle records the current feed in a new file. Square stops both other actions.

ok, so it sounds like the RIO isn't opening the camera. We're labview so I can't diagnose anymore than that. Let us know if what markmcgary linked to works.

So we were able to get our axis camera to show up on the dashboard yesterday by changing the name of it to axis-camera. However, we're having problems connecting to it through our code. We are getting a connection refusal when we access it as such:

AxisCamera camera = new AxisCamera("axis-camera");

Any ideas?

Did you try it with .local appended to your address name?

Yes I did. Both gave the same failure. I will get the exception on Saturday and post it.

Here is the exception we get when trying to run with

AxisCamera("axis-camera.local");

We've successfully used the AxisCamera class using both ip address and axis-camera.local using the Axis Camera Sample program.

Have you had any success doing a color threshold of the image?

I was able to run the 2015 Vision Color Sample, which does a color threshold. I modified it (few lines of code) to get the data from the axis camera, rather then a file. It does a color threshold to find the yellow bin.

Where is Vision Color Sample located?

Edit: Never mind, found it after the Java update.

We were finally able to get it running, but not with the AxisCamera. The robotRio sees the IP camera as cam0, so I was able to use it just like the USB cameras. Thank for the help.
