| 摘 要： | LiDAR技术已经被广泛地应用于城市三维模型的重建.本文在现有方法的基础上,探讨了一种基于数字图像分析技术提取建筑物边界的方法,该方法首先将LiDAR点云数据量化生成灰度影像,然后利用图像分割、边缘检测等图像分析技术将建筑物信息与地面特征分离开,最终提取建筑物的轮廓线.实验结果表明,这种方法能够比较准确地反映建筑物的边界,效果理想.

| Abstract: | LiDAR data had been widely used in 3D building construction.The paper discussed a method for building extraction from LiDAR data based on digital image processing.Firstly,the LiDAR point cloud data was quantified by 256 degree and then translated into gray image;secondly,the image segmentation and edge detection algorithm was applied for edge extraction of buildings.The test result showed that the method could extract building exactly,and had great reference in practice. |
