I downloaded and reviewed the paper, and I applaud you for publishing it. I do have a number of questions it didn't answer.

I didn't see a description of which image feature was used to estimate the distance. The accuracy of the distance measurement will depend largely on the resolution of the camera and the pixel size of that feature. One quarter inch accuracy seems to be a tall order even at twenty feet. Interpolation of other image features can be used once you can make assumptions about a feature, but that wasn't mentioned.

Also, couldn't the approaches in the paper be applied to other cameras? It doesn't seem like IR is a requirement for the approach either?

Good job taking on the challenge and good luck in the competition.
