The most likely cause for not matching is that the scale is wrong.

Team 2468 built the sign they wanted to use, held the sign standing behind the line. We used Vision Assistant to capture the image, opened it into the Geometric Match, trained it by selecting the content and saving as a png.

The code is generic, and it is the file that you would change if you wanted to adapt to a new sign. The matching parameters are actually rather strict. The more variation you tell the function to expect, the longer it takes to complete.

If you experiment with the distance or scale of the sign, you can probably get it to work, but perhaps it would be easier, and more informative to just train it again on your own sign. May I suggest "WE APR3C8", or something similar.

The other thing to glance at in Vision Assistant is to zoom in and verify that the green contours trace most of the high contrast area. If not, experiment with the way you hold the sign, the sliders for contrast, etc. I believe that 2468 uses pretty standard settings.
