58 +=== Vision/Ball Detection ===
76 76  
60 +* Flashing lights need to be masked or excluded by means of color to prevent misdetections
61 +* The pixel coordinates should be translated to a custom coordinate system, s.t. chnages in resolution or exact camera position can be abstracted from

67 +* For now the physics model passes a single number, the time the ball is predicted to be in range, i.e. when to trigger the flippers.
68 +For the logic to be able to perform meaningful computation more information needs to be passed, e.g.:
69 +** **Position** the ball is predicted to be at at the corresponding time
70 +** **Velocity **vector of the ball
71 +* Gravity on (% lang="en" %)inclined plane
72 +
73 +* (% lang="en" %)Different ball behavior when rolling down the inlanes

75 +* (% lang="en" %)Bounce back on collision, especially with the resting flippers (not all shot should be taken as a volley)
