54 -== Components ==
55 -
56 -This section is meant to collect the latest considerations for the system components.
57 -
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)
76 -
77 -=== Main Program ===

81 -== Hardware ==
82 -
83 -* Raspberry Pi 3 B+
84 -(((
85 -* 4 CPU-Core
86 -* 1 GB RAM
87 -* 26 GPIO-Pins
88 -)))
89 -
90 -* Pi NoIR Camera V2(((
91 -* Sony IMX219 sensor
92 -* 3280 x 2464 resolution
93 -* Up to 90 frames per second (at 640x480)
94 -)))
95 -
96 -* Relais box
97 -** Four 5V-relays (three in use)(((
98 -* To actuate the three flippers
