3D Roof Lines

Norwegian mapping standard Relevant roof lines in 3D Good: nice level of detail Bad: do not fully model the roofs, many flaws


Goals Classify laser data Convert camera calibration and bring in exterior

orientation Improve positioning of images Create 3D building models from roof line work Create textures for building walls Produce a fly over animation
