Abstract

This article describes a new method of three-dimensional (3D) camera calibration, in which the rotation parameters are decoupled from the translation parameters. The characteristic feature of this method is that the rotation parameters are obtained by projecting three sets of parallel lines independent of the translation parameters and the imaging distance from the lens to the image plane. This is because the virtual line passing through the image center, which is calculated by perspective projection of a set of parallel lines, depends only on the rotation parameters.
