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.

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:Projects.Archive.Pinball Project - Winter Term 201920.Project Documentation.Image ProcessingBall Detection.WebHome]]).
5 This pixel position is then transformed into a [[doc:Projects.Archive.Pinball Project - Winter Term 201920.Project Documentation.World Coordinate System.WebHome]] for further processing and passed to the [[doc:Projects.Archive.Pinball Project - Winter Term 201920.Project Documentation.SCChart Controller.WebHome]], which is the main logic component of the system.
6 To allow for timely reactions the [[doc:Projects.Archive.Pinball Project - Winter Term 201920.Project Documentation.SCChart Controller.WebHome]] calls the [[doc:Projects.Archive.Pinball Project - Winter Term 201920.Project Documentation.Ball Physics.WebHome]], which performs a ball trajectory prediction.
7 \\For a quick overview on how to build and run the system see [[doc:Projects.Archive.Pinball Project - Winter Term 201920.Project Documentation.Dependencies and Compilation.WebHome]].
