基于LiDAR点云数据的道路断面测量系统的关键技术研究

Research on Key Technologies of Road Section Measurement System Based on LiDAR Point Cloud Data

本系统将.net技术与LiDAR数据结合,通过开发一套基于断面数据提取的算法,变传统人工断面数据处理为机器自动化提取,从而构建了一套快速高效的自动化道路断面测量解决方案,解决了现阶段大范围高陡山区无法实地测量的问题。系统提供了方便的可视化交互界面和自定义参数配置,用户只需上传采集数据和中桩点数据即可完成横纵断面成果的输出,系统已在多项道路断面工程中测试应用。

The system combines.Net technology with lidar data,develops a set of algorithm based on section data extraction,changes the traditional manual section data processing to machine automatic extraction,and constructs a set of fast and efficient automatic road section measurement solution,which solves the problem that large-scale high steep mountain area cannot be measured in the field.The system provides convenient visual interactive interface and user-defined parameter configuration.Users only need to upload the collected data and middle stake point data to complete the output of the cross-section and vertical section results.The system has been tested and applied in many roads section projects.
