Limelight troubleShooting

Recently, we have trouble with our limelight. Although we can capture the reflective tape, we still can’t get the tx and ty. We have no idea what’s going on and how to fix it.

Just based on the image you posted you’re not tracking a contour even though it appears your HSV values could work-- you probably need to edit your contour filter. It’s hard to tell from this image, however, as it’s in “color” view which does not show the thresholded pixels (the “Show: color” selector below the video feed). A bounding box will surround the target and you can see tx/ty below the video feed. On a sidenote, I would personally slightly increase the hue range, lower the saturation minimum, and increase the value maximum.

If you are actually getting tx/ty values in the webview but mean you can’t get these in code, you should ensure you’re getting values as described in the documentation since it appears your networking is fine.
