1 +The described system is an autopilot for the pinball machine "Mary Shelley's Frankenstein".
2 +A Raspberry Pi with attached camera is mounted above the pinball machine and the computer is connected to the triggers of the pinball machine to allow for their actuation.

34 -program actuates flippers dependent on ball recognition
4 +The different parts of the system interact in the following way. From the live camera footage a ball position is extracted in a series of image processing steps (see [[doc:Image ProcessingBall Detection]]).
5 +This pixel position is then transformed into a [[doc:World Coordinate System]] for further processing and passed to the [[doc:SCChart Controller]], which is the main logic component of the system.
6 +To allow for timely reactions the [[doc:SCChart Controller]] calls the [[doc:Ball Physics]], which performs a ball trajectory prediction.

58 -=== Vision/Ball Detection ===
59 -
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

63 -=== Pinball Controller ===

65 -=== Ball Physics Model ===
66 -
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

73 -* (% lang="en" %)Different ball behavior when rolling down the inlanes
