屋顶

In the roof reconstruction, a TIN-based region growing is applied to extract the roof planes. The coplanarity and adjacency between triangles are considered for TIN-based region growing. Then, a least squares regression is selected to determine the coplanarity function of planar segment.

在建物屋顶面重建中，使用建物轮廓线内部的光达点云进行屋顶面之共面分析，研究中使用三角网区域成长法侦测共平面之屋顶面，以相邻三角网法向量夹角做为共平面门槛，并以最小二乘法回归出屋顶面之平面，产生房屋模型。

This paper discusses the problems of the roof design in northern frore area with the practice of dwelling house design for Changchun Finance Bureau. The discussion is from five aspects of roof obliquity, dormer window, flat roof, structure design and conformation design.

The experiment results showed that the classic roofs such as plane roofs, gabled roofs and L-shape roofs could be reconstructed successfully without any auxiliary information.

根据本实验的成果显示，ㄧ些经典的屋顶面，例如平屋顶、山形屋和L形屋顶皆可在没有任何辅助资讯的加入下，顺利完成屋顶面的重建。

First said the farm the roof are partial, Niu Qun roof which breedsdivides into 10; 6 roofs area peacefully fit out the transparent plateglass material, its function is the sunlight illumination, jogs,plays; 4 roofs area peacefully fit out not the opaque buildingmaterial, its function is sleeps the place which, the rest, andgrazes.

先说农场的屋顶部分，把放养的牛群的屋顶分成10份；6份屋顶面积安装成透明的厚玻璃材料，它的功能是阳光照射、跑步、玩耍；4份屋顶面积安装成不透明的建筑材料，它的功能是睡觉、休息、和吃草的场所。
