50 +== Components ==
51 +
52 +This section is meant to collect the latest considerations for the system components.
53 +
54 +=== Vision/Ball Detection ===
55 +
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
58 +
59 +=== Pinball Controller ===
60 +
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** of the ball
67 +* Gravity on (% lang="en" %)inclined plane
68 +
69 +* (% lang="en" %)Different ball behavior when rolling down the inlanes
70 +
71 +* (% lang="en" %)Bounce back on collision, especially with the resting flippers (not all shot should be taken as a volley)
72 +
73 +=== Main Program ===
74 +
75 +\\
76 +
77 +== Hardware ==
78 +
79 +* Raspberry Pi 3 B+
80 +(((
81 +* 4 CPU-Core
82 +* 1 GB RAM
83 +* 26 GPIO-Pins
84 +)))
85 +
86 +* Pi NoIR Camera V2(((
87 +* Sony IMX219 sensor
88 +* 3280 x 2464 resolution
89 +* Up to 90 frames per second (at 640x480)
90 +)))
91 +
92 +* Relais box
93 +** Four 5V-relays (three in use)(((
94 +* To actuate the three flippers
