摘要：A method for searching a building roof facet and reconstructing a roof
structure line, in which the searching is performed automatically and without limitation ofhow slope of the roof facet, and the building structure line is constructed through aerial
imagery. At first, lidar point clouds on the roof are extracted to compose a roof facet byusing coplanarity analysis, and the roof is differentiated to a possible flat roof and apitched roof. An optimal roof facet is obtained by analyzing lidar point clouds toovercome the low pitched facet issue. A relationship of a roof facet on a 2-dimensionalspace is analyzed to ascertain an area of a roof structure line. An initial boundary isgenerated. Line detection is performed on the images and a roof structure line segmentis composed. All the structure line segments are used to reconstructing a 3-dimensionalbuilding pattern in object space.
