铁路及周边构筑物高精度点云信息采集系统

铁路及周边构筑物高精度点云信息采集系统是一套用于运营铁路（普铁、高铁、地铁、有轨）的轨道参数和沿线三维点云的移动测量系统（也称“SYH-GM9000全要素采集车”），应用于铁路和隧道的竣工验收和运营监测阶段。系统的软件部分包含数据采集软件、数据融合软件、点云成果显示软件、数据分析软件、数据管理平台等，系统的硬件部分由进口激光断面仪、高精度惯导、多星多频GNSS定位模块、三防平板电脑、轨距传感器、里程计、同步采集模块、长续航供电模块等组成。该系统可以完成轨道线路控制测量（平面和高程）和内部参数测量（轨距、超高、平顺性、TQI等）；同时可用于地铁盾构净空、椭圆度、环间错台测量分析，隧道衬砌病害检测，铁路沿线路基、接触网限界测量分析，铁路沿线桥梁偏心测量分析，站台、雨棚限界测量分析，铁路沿线资产调查管理等。

The High-precision Point Cloud Information Acquisition System for Railways and Surrounding Structures is a mobile measurement system (also known as the "SYH-GM9000 All-factor Acquisition Vehicle") dedicated to collecting track parameters and 3D point clouds along operational railways including conventional railways, high-speed railways, subways and trams. It is applied in the acceptance inspection and operation monitoring phases of railways and tunnels. The software part of the system includes data acquisition software, data fusion software, point cloud result display software, data analysis software and data management platform, etc. The hardware part consists of imported laser profilers, high-precision inertial navigation systems, multi-satellite multi-frequency GNSS positioning modules, rugged tablets, track gauge sensors, odometers, synchronous acquisition modules and long-endurance power supply modules, etc. This system can conduct track line control surveys (plane and elevation) and internal parameter measurements (track gauge, superelevation, smoothness, TQI, etc.). It can also be used for measurement and analysis of metro shield clearance, ellipticity and inter-ring misalignment, tunnel lining disease detection, measurement and analysis of railway subgrade and catenary clearance along railways, analysis of bridge eccentricity along railways, measurement and analysis of platform and awning clearance, and asset investigation and management along railways, etc.
