基于激光点云数据绘制城市地下民防工程平面图

Drawing the City Underground Civil Defense Plan Based on Laser Point Cloud Data

地下空间平面图对于地下空间的开发利用具有重大意义,可以直观显示出城市地下空间的范围和大小。采用徕卡C10三维激光扫描仪获取某地下民防工程的激光点云数据,使用Cyclone软件完成对激光点云数据的预处理,基于CoSurvey2016软件绘制地下民防工程平面图,通过激光测距仪量测距离对比验证其精度。试验结果表明:利用激光点云数据绘制城市地下民防工程平面图可以满足工程精度要求。

The plan of underground space is of great significance to the development and utilization of underground space,which can directly show the scope and size of urban underground space.This paper uses Leica C10 three-dimensional laser scanner to obtain point cloud data of an underground garage,uses Cyclone software to complete the preprocessing of point cloud data,and uses CoSurvey2016 software to draw the plan.The accuracy of the laser rangefinder is verified by comparing the measured distance.Experimental results show that the laser point cloud data obtained by Leica C10 three-dimensional laser scanner can meet the accuracy requirements of urban underground space plan drawing.
