建筑点云的平立剖图生成方法
Plane and Facade Section Drawings CreationBased on Point Clouds of the Building
摘要
Abstract
The plane and fa ade section drawings of a building contain vector elements of structure wireframe,as well as the attribute information like materials,sizes,and decoration information.The plane and fa ade section drawings can accurately and visually show the real state of the building,which is essential to the protection for the historic buildings.By slicing the point clouds of the building,the slice point clouds could be obtained.The slice point clouds were organized with reference tothe image grid form.The contour feature points were obtained by barycentring the feature points in the grid.Then the contour feature lines were established on the basis of the connection of two-way cortege line segments.Finally,the plane and facade section drawings of the building were created.By comparison with traditional drawing methods for the plane and facade sections,the method put forward in this paper can reduce the manual work and increase efficiency.关键词
