Abstract
Depth estimation is a classic machine vision and image processing
problem aiming at mapping the distances of objects from the camera.
The accuracy of this depth map depends on the axial resolution
achieved by the system, which is usually estimated using geometrical
optics theory. This paper proposes a novel formula using diffraction
theory. A comparison with the geometrical approach for estimating the
axial resolution is provided, and results for several simulations are
discussed.
