1. A method for reconstructing-three-dimensional (3D) lines in a 3D world coordinate system from two-dimensional (2D) lines in a single image of scene, comprising the steps of:
- detecting and clustering the 2D lines using vanishing points;
generating a constraint graph of vertices and edges, wherein, the vertices represent the 2D lines, and the edges represent constraints on the 2D lines;
identifying the constraints on the 2D lines that are satisfied on the 3D lines; and
reconstructing, the 3D lines in the 3D world coordinate system using the identified constraints.

Abstract
A method for reconstructing—three-dimensional (3D) lines in a 3D world coordinate system from two-dimensional (2D) lines in a single image of scene detects and clusters the 2D lines using vanishing points. A constraint graph of vertices and edges is generated, wherein the vertices represent the 2D lines, and the edges represents constraints on the 2D lines, then identifying the 3D lines that satisfy the constraints and reconstructing the 3D lines using the identified constraints.
