PROBLEM TO BE SOLVED: To provide a method for reconstructing 3D lines in a 3D world coordinate system from 2D lines extracted from a single 2D image.SOLUTION: A method for reconstructing three-dimensional (3D) lines in a 3D world coordinate system from two-dimensional (2D) lines in a single image of a scene includes: detecting and clustering the 2D lines using vanishing points; generating a constraint graph of vertices and edges, where the vertices represent the 2D lines and the edges represent constraints on the 2D lines; and then identifying the 3D lines that satisfy the constraints to reconstruct the 3D lines using the identified constraints. |
