Do you see anything in that image that would make it not be able to find the obvious red target? Its lined up, and the camera 3 ft off the ground as the instructions say. I'm completely out of ideas, can anyone help? |
Pickle,
I set up a "test bed' with ideal conditions, a black sheet and mini triangles placed about 3 feet away from the camera to really get a good understanding of what's going on and how all the camera parameters work. The GUI stores "tuned" RGB values for FIRST's selected colors in config.txt in the .java folder. You might want to just highlight the triangle in the frame grab window and make sure the RGB values displayed next to the grab fall within range of the parameters for that particular color in config.txt. If not, your colors and/or lighting may be off. You might want to alter the values in config.txt to get it going.
After getting a firm understanding on how this thing finally works and how to tune it, I'm really concerned about how well everything will work as a "system" on the field dealing with variations in lighting and the field. I wonder if FIRST will allow us to read the mean values off the real targets before the competitions. I can see it now.....tee shirts with 120 255 0 20 25 300.... written all over them.
Good Luck. Let me know if I can help.
