Adding Crosshairs to SmartDashboard?

[RugnarStormBorn]

Does anyone know how to add crosshairs to Smartdashboard through the code? If so, how did you manage to go about that?

Thanks in advance!

I'm not sure exactly what you mean. Are you trying to move a crosshair around on the dashboard? or superimpose one on a camera feed? or something else?

If you want a crosshair on anything on the dashboard, just click add>Image and upload an empty image. Then resize to a line and put it where you would like.

go to the FRC Vision palette for IMAQ and go into overlay pallette - there are tools to add lines, rectangles, circles, etc...like the "turtle graphics" code of yore

Any way to do this on Java? I feel like Your suggestion is for Labview, Elkbits. Thanks.

You might be able to make your own smartdashboard widget that uses OpenCV to draw on the image.

We put a piece of clear plastic over the screen, and draw on it.

This. Sometimes the old-school hacks are quicker, easier, and just as effective as trying to do something the "right" way. We've used clear plastic (overhead transparencies, can buy a box of them at any Office supply store) for years!

We've cut up some electrical tape and put it on the screen.

Last year, we used a few connection indicators stretched into lines as crosshairs.

Same

Apparently, You can also overlay static images on the SmartDashboard pretty easily. Anyone thoughts on dynamic displays?
