How you mount your camera ? at exact 35 degree ?
I do a lot of scan today with the 20mm calibration board , I just found out that the wider the angle of the two camer the smaller output it gets( on east-west side ), the more narrow , the bigger number, I didn't do any marking on my mount so I guess I hit it around 35 degree now since the out put is almost exact 20mm.
However, the on the north/south side is still off about 1mm, I think the the projector height and the angle of projection that matter, do you rememebr what's the till angle of your projector ? do you use any lens swift ?
