A Great Circle Arc Detector in Equirectangular Images

Abstract

We propose a great circle arc detector in a scene represented by an equirectangular image, i.e. a spherical image of the 360 longitude and 180 latitude field of view. Since the straight lines appears curved in equirectangular images, the standard line detection algorithm cannot be used directly in this context. We extend the LSD method (Gioi et al., 2010… (More)
