Optimal Depth Estimation from a Single Image by Computational Imaging Using Chromatic Aberrations / Optimale Tiefenschätzung in einer Einzelaufnahme mittels Computational Imaging anhand chromatischer Aberrationen

Abstract: We present a computational imaging approach to estimate the depth from a single image using axial chromatic aberrations. It includes a co-design of optics and digital processing to select the optimal parameters of a lens such as focal length, f -number, and chromatic focal shift according to the performance of a depth estimation algorithm on the digital side. A simulation framework evaluates the complete systems performance in different imaging conditions including optimal axial chromatic lens aberration. A lo… Show more

“…To make the best out of it, we intentionally even strengthened the chromatic aberration in order to utilize it for an extended depth of field, EDoF. The basic concept is known from literature [2,3]. The refractive index n(λ) of optical glass or plastic material decreases with increasing wavelength.…”
