Over estimating size of targets #10

Closed zachkendrick closed 7 years ago

zachkendrick commented 7 years ago

Have you found that the algorithm slightly over estimates the side lengths of the targets by about 1cm or so? It's causing the calibration to be off...

Yes, while testing we also encountered a slight difference in the length of the sides (+-1cm if I remember correctly). It could cause a slight error but multiple iterations should be able to deal with that and mitigate its effect.
