Abstract:
Smartphone camera lenses have become prevalent. Photographs, and video, taken by such lenses have many useful applications which depend on accurately knowing the distortion properties of the lens. In this paper, we present an accurate method to determine smartphone camera lens distortion to an estimated average error of 0.09%. We present a linear regression method and account for keystone distortion and conjugate change.
