I was looking to see what kind of depth error I could expect using the stereo cameras here://www.samlea.com/support/resources/calculator/
On plugging in different values for "expected disparity error", I expected the depth error to vary linearly. But that doesn't seem to be the case.
I was using the formula
delta_Z = Z^2/(B*f) * delta_D
Z is target depth
B is baseline
f is focal length
delta_D is expected disparity error
Is there something else in the nerian stereo cameras that I have to take into account?
