Resumo: A building can be reconstructed from its roof, which can be defined by someparameters like orientation, height, ridges and contours. In many models forbuilding extraction, using Laser scanner raw data, plants are requested to accomplish the precise location of building contours. The purpose of this study is topresent a method for building reconstruction using Laser scanner data. For this, the2D Hough transform is applied to the Laser data, represented as a raster image, tofind the borders of the roof. Then, the planes that model the roof are estimated andthe form of the roof is derived. The method proved to be efficient in buildingmodeling. In the pre-processing step, the Hough transform and thinning were usedto estimate the borders of the buildings. The method to find the planes of the roof iseffective and consists of looking for three points that define each plane of the roof.The ridge lines are got by intersecting these planes.

Para tanto, determina-se asextremidades do telhado, encontra-se os planos e pontos do Laser que compõemcada face do telhado, realiza-se a interseção dos planos gerados para localizar acumeeira e, finalmente, utiliza-se estes parâmetros para reconstruir a edificação.Este método apresentou eficiência na reconstrução das edificações. No préprocessamento,foi utilizada da transformada de HOUGH, para encontrar as retaspertinentes aos limites das edificações, após a utilização de um algoritmo deesqueletonização para o afinamento das bordas, a qual mostrou-se uma ferramentaeficiente que ameniza o deslocamento das bordas e otimiza o processamento datransformada de HOUGH. O método para determinar os planos do telhado consisteem localizar, de modo automático, três pontos que definam um plano eposteriormente a determinação da cumeeira é realizada por meio da interseção dosplanos formados.Boletim de Ciências GeodésicasBulletin of Geodetic Sciences2007-07-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufpr.br/bcg/article/view/8248Boletim de Ciências Geodésicas; Vol 13, No 1 (2007)Bulletin of Geodetic Sciences; Vol 13, No 1 (2007)1982-21701413-4853reponame:Boletim de Ciências Geodésicasinstname:Universidade Federal do Paraná (UFPR)instacron:UFPRporhttps://revistas.ufpr.br/bcg/article/view/8248/5789Botelho, Mosar FariaCenteno, Jorge Antonio Silvainfo:eu-repo/semantics/openAccess2007-07-09T14:11:53Zoai:revistas.ufpr.br:article/8248Revistahttps://revistas.ufpr.br/bcgPUBhttps://revistas.ufpr.br/bcg/oaiqdalmolin@ufpr.br|| danielsantos@ufpr.br||qdalmolin@ufpr.br|| danielsantos@ufpr.br1982-21701413-4853opendoar:2007-07-09T14:11:53Boletim de Ciências Geodésicas - Universidade Federal do Paraná (UFPR)false
