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 **vector 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
95 -)))
