Make the Dot-To-Dot more reliable #155

Open JackBuck opened 7 years ago

JackBuck commented 7 years ago

From time to time the plotter makes false positive number recognitions. We need to do everything we can to make this more reliable!

Ideas for detecting false positives:

If it has recognised a number in two different places, look again at all numbers with those values.
If the last two/three numbers are not consecutive, look again at the last number.
Reject all three-digit numbers.

Ideas for reanalysing without needing to take extra photos:

Apply a small rotation to the image, then analyse again (probably rotate it clockwise slightly, since being slightly too far anticlockwise has caused more problems in the past).
(Dynamically) replace the camera object in the plotter with one with a higher resolution.
Save the image as .jpg then reload and reanalyse (magically this seems to positively affect the results!)

The majority of this issue has been merged. However, because of unnoticed type 2 errors, I think it would be worth saving the image as .jpg and reloading it.
