Identifying rectangles in laser range data for urban scene reconstruction
2011
Computers & graphics
Preserved Fulltext
In urban scenes, many of the surfaces are planar and bounded by simple shapes. In a laser scan of such a scene, these simple shapes can still be identified. ...
We prove that our algorithm identifies all angles for which a rectangle fits the point set of size n in OðnlognÞ time. ...
We thank Ron Wein and Efi Fogel for their help concerning the CGAL boolean set-operations library. ...
