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.
1 +== Project Milestones ==
3 3  
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.
7 -\\For a quick overview on how to build and run the system see [[doc:Dependencies and Compilation]].

56 +This section is meant to collect the latest considerations for the system components.
18 18  
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
62 +
63 +=== Pinball Controller ===
64 +
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
72 +
73 +* (% lang="en" %)Different ball behavior when rolling down the inlanes
74 +
75 +* (% lang="en" %)Bounce back on collision, especially with the resting flippers (not all shot should be taken as a volley)
