基于等高线族分析的Li DAR点云建筑物模型自动识别及重建

Automatic Recognition and Reconstruction of LIDAR Point Cloud Building Model Based on the Analysis of Contour Line Family

传统的LiDAR点云建筑物模型会经常受到二维图纸的局限,极大地影响对建筑物的判断。而对于等高线族的分析,从等高线族的特性到建筑物等高线的划分,都能通过等高线的识别呈现建筑物的形状和结构,从而提高建筑物模型重建的效率。论文从等高线族的定义、机载LIDAR技术、屋顶识别、模型重建等方面,探讨基于等高线族分析的LiDAR点云建筑物模型自动识别及重建。

The traditional LIDAR point cloud building model is often limited by two-dimensional drawings,which greatly affects the judgment of buildings.As for the analysis of contour family,from the characteristics of contour family to the division of building contour line,the shape and structure of buildings can be presented through contour line identification,thus improving the efficiency of building model reconstruction.From the definition of contour family,airborne LIDAR technology,roof identification and model reconstruction,this paper discusses the automatic recognition and reconstruction of LIDAR point cloud building model based on contour family analysis.
