基于实景激光扫描技术的室内导航系统的建立

随着城市化进程的发展,人们在室内的时间越来越多,室内空间的应用价值也越来越高。在智慧城市的发展过程中,大量的室内空间需要数字化,室内空间数据的获取手段和数据应用需要进一步挖掘。本文利用三维实景激光扫描仪对北方工业大学浩学楼进行数据采集,创建了实景展示和实景导航,重点介绍了M3扫描车获取点云数据,并将点云数据进行拼接、去噪等处理,最后分析了点云数据的精度。由此可以得出实景激光扫描技术在建立室内导航系统中的可行性、高效性和准确性。

Establishment of Indoor Navigation System Based on Real-scene Laser Scanning Technology

With the development of urbanization process,people stay more and more time indoors,and the application value of indoor space is getting higher and higher.In the development process of smart city,a large number of indoor spaces need to be digitized,and the means of obtaining indoor spatial data and Data applications need to be further explored.In this paper,3D real-scene laser scanner is used to collect data from Haoxue Building of North China University of Technology,and real-scene display and real-scene navigation are created.The M3 scanning vehicle is introduced to acquire point cloud data,and the point cloud data is spliced and denoised.Finally,the accuracy of the point cloud data is analyzed.the feasibility,efficiency and accuracy of real-scene laser scanning technology in establishing indoor navigation system can be obtained.
