StreetMapper地图法国铁路，用于更安全的轨道

适合ESIC帮助法国国家铁路广告样稿any SNCF improve safety and inform track upgrade works with a mobile laser scanning system from 3D Laser Mapping. Owned and operated by FIT ESIC, the rail mounted StreetMapper was used to survey several hundreds of kilometres of track, generating engineering grade survey data on behalf of SNCF. The laser generated computer model was used to build a detailed 3D topographic map of the tracks and its surroundings. This provided length data and cross profiles as well as detecting potentially dangerous objects near the track.

“Since we took delivery of our StreetMapper system we have surveyed thousands of kilometres of roads as well as hundreds of kilometres of railway tracks,” commented Marc Daeffler, Director of the Engineering Division at FIT ESIC. “By working closely with various SNCF engineering teams; survey, track and cantenary, we came up with innovative solutions, utilising StreetMapper to capture and extract large amounts of geometric information.”

Fit Esic还与位于英国StreetMapper的3D激光映射的开发商并排合作，除了SNCF中的技术团队外，还克服了与在铁路上工作相关的潜在挑战。其中包括沿着赛道的人员的访问，以测量控制点，在铁路运输范围内的激光映射系统的安装和操作以及由火车运动引起的强烈振动。3D激光映射还通过设计特定算法来处理轨迹的算法也支持了拟合ESIC。

SNCF工程援助和测量部负责人布鲁诺·兰德斯（Bruno Landes）（SNCF（Societe Nationale des Chemins de Francais）法国国家国有铁路公司，他补充说：“ LIDAR Technology毫无疑问改善了我们铁路基础设施的管理。例如，数据已用作铁路现代化研究，仪表研究和电气化研究的地形输入。”

Data created from the millions of individual laser scanned measurements include a 3D topographic map of the track and its surroundings including powers lines, stations and trackside equipment. Length and cross profiles of the track were generated including cantenary lines, staggers of contact lines and overhead civil engineering structures. Potentially dangerous objects were detected, identified and measured to determine clearance from the track and trains.

StreetMapper专门为高速公路，跑道，铁路，基础设施和建筑物的快速3D映射而设计。使用提供360度视野的车辆安装激光器，StreetMapper可实现高精度映射到800m的范围，每秒每秒550,000个测量值的容量为550,000，并且在比10mm更好的独立现实世界中记录了绝对精确度。

SNCF manages rail traffic in France and operates the country’s national rail services, including the high speed TGV rail network. SNCF’s functions include operation of railway services for passengers and maintenance of signalling and rail infrastructure.
