摘要
提出了一种基于地面激光点云的室内平面地图生产方法。利用地面激光扫描快速获取建筑物室内外的三维点云信息,再经过点云拼接、切片、规则化等处理,半自动地勾绘室内外墙体轮廓线和墙体中心线,然后对室内典型要素进行分类提取,最终生成与地形图坐标系相一致的室内平面地图。实例验证结果表明,室内平面地图的精度优于5 cm,可满足室内定位与导航的应用需要。
In this paper,we introduced an indoor planimetric map production method based on terrestrial laser scanning.We rapidly acquired the 3D architectural point cloud data both inside and outside at first.And then,through point cloud registration,section and regularization,we extracted the outlines and center lines of the walls and classified the typical indoor elements.Finally,we produced indoor planimetric map which unified the coordinated system with topographic map.The application result shows that the accuracy of the indoor planimetric map is better than 5 cm,which can meet the requirements of indoor positioning and navigation.
