Todo
- run 1/21 images through image library to determine best algorithm to use (hull vs edge)
- use color or grayscale camera image (will depend on algorithm used)
- determine how fast NI image library is (if using edge detect, might want to right that part ourselves)
- test green and white led ring when they come in
- ...

Notebook
1/15: tested white and red led reflections
- Target: 26 feet from camera; OSB; tape is black duct tape (note: not enough tape to do inside completely)
- Light Sources: 1) Round light with several red leds (something from a prior year); 2) Mini-led flashlight (red from toolbox), has 5 wihtie leds
- Results: The red led gave off a little red cast (each time we connected power, a different number of leds lit up). The white leds reflected the best. Concerned the white leds might be too bright for drivers on other alliance
- Images: 1) No light source; 2) Red led light; 3) Mini flashlight
1/19: tested Infrared lights reflecting off reflective tape for the camera
- Target: about 4 feet from camera (we did not measure it); poly; outer tape is black duct tape and inner tape is blue gaffers tape; in the middle of the target, the plastic protection is on the back; area outside the black tape has the plastic protection on both sides
- Light Sources: 1) infared LED Night light, Model # IR045; 2) Mini-led flashlight (red from toolbox), has 5 wihtie leds
- Results: Camera can infrared light, but no reflection on tape (you can also see reflect on the plastic).
- Images: 1) No light source; 2) Infared light; 3) Mini flashlight
1/21: ran edge detection on images from 1/15 and 1/19
- 1/15 Images: 1) No light source; 2) Red led light; 3) Mini flashlight
- 1/21 Images: 1) No light source; 2) Infared light.png; 3) Mini flashlight
1/21: Took lots of pictures of the target:
- From various distances/locations:
- up against Fender
- sideways at Fender
- top of Key
- corner of Key
- at center Bridge
- at alliance Bridge
- At all three hoop heights
- Taking into account sideways displacement of middle hoops
- Some with light shining on the retro-reflective tape, some without
- Some with mock "hoop", some without
- Some with balls blocking parts of target, some without
- Target always approximately in the center of the picture
- This assumes variable-angle camera
1/22: Image processing
- Converted 1/21 images. The lit reflective tape does improve the edge detection. The balls and hoop do block the target, so this will need to be taken into account.
