Correcting distortion of views into aquarium

Abstract

In this paper, we discuss a way to correct light distortion of views into an aquarium. When we see fish in an aquarium, they appear closer also distorted due to light distortion. In order to correct the distortion, the light rays travelling in the aquarium directly towards an observer should hit him/her after emerging from the aquarium. A basic idea is to capture those light rays by a reference camera, then merge the rays as a single view, which is displayed to the observer. An experiment in a real world environment shows that light distortion of a view into an aquarium can be corrected using the multiple reference camera views. © 2013 Springer-Verlag.
