摘要
传统铁路限界测量作业效率低,难度大,如何高效且精确地获取限界数据成为铁路建设亟需解决的问题,为此,提出了将三维移动激光扫描技术运用于铁路限界测量的方法。通过实际工程应用后,与传统限界测量结果进行对比,结果显示,移动激光扫描测量具有自动化程度高、获取数据速度快、点云数据量大、精度可靠性高以及数据处理迅速等优点,今后可将该技术在类似工程测量项目中推广应用。
Conventional railway clearance measurement operations are characterized by low efficiency and high complexity.The efficient and accurate acquisition of clearance data has become a pressing issue in railway construction.To address this challenge,a method is proposed that utilizes 3D mobile laser scanning technology for railway clearance measurement.Through practical engineering applications and a comparison with results obtained from conventional clearance measurements,the outcomes reveal that mobile laser scanning measurements exhibit advantages such as high automation level,rapid data acquisition,substantial point cloud data volume,high accuracy and reliability,and swift data processing.Consequently,this technology holds promising potential for broader application in similar engineering measurement projects in the future.
