I'm glad to hear my idea is not unique (and therefore not impossible/ innacurate). I'm a bit curious if the image is close enough to flat to assume the deg/pixel value can be treated as a constant and still be accurate, or if just the edges should be treated with a different rate, etc.
Also, according to the
datasheet the M206 has a field of view of 54 deg (assuming linearity here) is that accurate enough value to use?
Sorry if I'm asking for a handout a bit here, I'm just trying to avoid going overboard on gathering a ton of sample images and doing a ton of trig only to find out I could have just taken 54/320.
