Note that a chipped ball only moves in a straight line across the image, when it moves along an image axis. Nearer to the edges, it rather moves in a curve.
Also note, that due to the height, the ball blob gets bigger. If the size exceeds the maximum blob size for the ball, it won't be detected as well.
I'm actually not sure if it is really an issues. It would only be one sample in many, right?
Two suggestions:
- Check the raw ball data in the game logs. You should roughly see if a sample should be above a robot and if it actually is.
- Check SSL_DetectionBall#area in the detection messages. It should give the area of the ball blob. The default for "Max Area (sq-pixels)" is 1000.
