1. Mark the ball’s outer track
Choose the roulette browser tab when Chrome asks. On a clear, fixed wheel view, drag a rectangle around the outer ball track below. The ellipse must follow that track. Tracking then runs automatically.
Green ellipse: ball search band. Gold ellipse: rotating pocket ring. Fit the green ellipse tightly; adjust the gold radius to the pocket texture. Recalibrate after camera cuts, zoom, scrolling or layout changes. Keep this observer window visible beside the table. Hidden-tab throttling can stop reliable measurements.
2. Check the measurements
Landing-pocket prediction
A physical outcome model also needs verified ball identity, perspective calibration, pocket/zero reference, drop behavior, deflector and bounce calibration, and predictions validated before betting closes. None of those are established by this tracker.
Speeds are estimates in the marked screen ellipse, not calibrated three-dimensional measurements. Reflections, compression, motion blur and camera movement can cause false tracks. Check the mint marker actually follows the ball.
