53 +
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 ===
78 +
79 +\\
80 +
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
