Review on coupled line cameras and its application in rectangle reconstruction from a single image

摘要

The concept of coupled line cameras (CLCs) is reviewed as a novel geometric tool in computer vision with special emphasis on the application of perspective reconstruction of an unknown scene rectangle from a given single image taken from an uncalibrated camera. We give real-world examples where the aspect ratio of a scene rectangle can be precisely reconstructed as well as the internal and external camera parameters, assuming a simple camera model.
