# Stereo-camera depth resolution
# Scope: Rectified stereo pinhole depth; disparity and focal length in pixel counts.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

baseline = 100 mm
focalPixels = 800
disparity = 40
disparityError = 0.5

depth := baseline*focalPixels/disparity [mm]
depthError := baseline*focalPixels*disparityError/disparity^2 [mm]

check depth uncertainty budget: depthError <= 30 mm

scenario alternative: baseline = 80 mm
