I looked at the LV code and the camera FOV values being used are 48deg for the Axis 206 and 43.5deg for the M1011. I don't have an M1013 to measure.

I modified the FOV numbers from the data sheet last year as well.

I don't recall whether the data sheet indicated that this was a diagonal measurement vertical, or horizontal. And I'm not sure how it was measured or how accurate it was. I didn't test it at many distances this year, but last year's seemed to be accurate at a number of distances once the FOV was corrected.

Obviously this approach is not accounting for barrel distortion and planar distortions when the camera sensor isn't parallel with the wall, but those aren't expected to be significant and this was an attempt to keep the math somewhat simple.
