1 -The descibed 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 maschine to allow for their actuation.
1 +== Project Milestones ==

4 -The differnt 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]], wich is the main logic component of the system.
6 -To allow for timely reactions the [[doc:SCChart Controller]] calls the [[doc:Ball Physics]], which performes a ball trajectory prediction.

56 +* Flashing lights need to be masked or excluded by means of color to prevent misdetections
57 +* The pixel coordinates should be translated to a custom coordinate system, s.t. chnages in resolution or exact camera position can be abstracted from

61 +=== Ball Physics Model ===
62 +
63 +* 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.
64 +For the logic to be able to perform meaningful computation more information needs to be passed, e.g.:
65 +** **Position** the ball is predicted to be at at the corresponding time
66 +** **Velocity **vector of the ball
67 +* Gravity on (% lang="en" %)inclined plane
68 +
69 +* (% lang="en" %)Different ball behavior when rolling down the inlanes

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