20.1 | 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. | ||
| |
19.1 | 3 | |
| |
24.1 | 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:PP18.Pinball Project - Winter Term 201920.Project Documentation.Image ProcessingBall Detection.WebHome]]). |
| |
26.1 | 5 | This pixel position is then transformed into a [[doc:PP18.Pinball Project - Winter Term 201920.Project Documentation.World Coordinate System.WebHome]] for further processing and passed to the [[doc:PP18.Pinball Project - Winter Term 201920.Project Documentation.SCChart Controller.WebHome]], which is the main logic component of the system. |
| |
25.1 | 6 | To allow for timely reactions the [[doc:PP18.Pinball Project - Winter Term 201920.Project Documentation.SCChart Controller.WebHome]] calls the [[doc:PP18.Pinball Project - Winter Term 201920.Project Documentation.Ball Physics.WebHome]], which performs a ball trajectory prediction. |
| |
23.1 | 7 | \\For a quick overview on how to build and run the system see [[doc:PP18.Pinball Project - Winter Term 201920.Project Documentation.Dependencies and Compilation.WebHome]]. |
