Re: Finding range
to get the highest degree of precision you want to use the full range of the camera system, so that at the furthests distance the reading is at one end of its range, and at the closest distance its at the other end.
I want to say the camera should be mounted near the floor, to get the greatest change in angle between close and far, but I dont know all the details of how the camera works
but look at it this way, if you mount the camera at the same height as the light, you wont be able to measure distance at all, right?
if you cant put the camera lower, maybe you can put a mirror lower on your bot, and point the camera at the mirror, so it sees the light through the mirror?
