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? |
1) Lighting is extremely important as others have stated. In your picture, the automatic exposure control is adjusting based on the brightest spot in your frame, which are the white sheets. I'm guessing they are very bright (reflecting the lights in the room), and so the camera is under exposing the important parts of the frame (the red triangle).
2) If you have no control over lighting, the next best thing is to skip the calibration process altogether, and manually enter numbers in the text fields beside the calibrate buttons. If you want some numbers to start with:
Yellow = 36
Green = 44
Red = 90
we got these values working in a large highschool cafeteria with fluorescent lights covered with dingy yellow covers.
Once you enter these values, click on the "Color" tab, then click Track [Color], and see how it looks. If you only see small patches of your triangle, increase the number for that color. If you're picking up areas of color from the surrounding area, then drop it down.
Good luck!
