运动革命

Severn Partnership strives to provide services to its customers using the very latest and inno-vative solutions. Since acquiring the Leica Pegasus:Two, the firm of Chartered Geomatics (Land) surveyors based in Shrewsbury, United Kingdom, has utilised this cutting-edge technology in various infrastructure and construction projects for their customers. Keen to pass on the benefits of this new technology, Severn Partnership was delighted to be commissioned to survey a section of the M6 to collect important assets for their risk and maintenance strategy plan. A full detailed survey of a 17 kilometre (10 mile) section of the M6 in the Midlands area included carriageway limits, crash barriers, assets such as road signs and SOS phones, centre lines, central reservation, bridge structures and lamp posts. The survey was needed to improve the overall layout of the motorway ensuring regular maintenance checks can be maintained eradicating pot holes and maintaining a smooth and safe road surface for drivers.

The challenges of surveying a section of the M6 motorway are vast, and closing this section of the busy motorway was not an option. Restrictions to access were a serious issue as the motorway need-ed to remain open whilst the data was collected. Also, the vast volume of assets to be surveyed on a motorway in a short period of time was also important to remember. Using traditional total station instruments to carry out this project would have taken twice the time of using a Pegasus:Two, collecting thousands of points of survey data per day. Logistically and practically speaking, it is dangerous for surveyors to collect data in the middle of a motorway. The overall cost of the project increases with the need for active traffic management throughout the project cycle. A more efficient collection process was needed.

The best solution for mapping the M6 motorway
Severn Partnership使用了移动映射 - 从移动车辆收集3D地理空间信息的过程 - 快速准确地为客户提供2D和3D CAD计划以及整个路线部分的完全注册点云。这些点云是在激光器反射的任何内容上测量的数百万个单独的坐标，例如桥梁和道路，可用于提取更多信息，例如GIS数据集。该设备连接到移动车辆的车顶上，然后每2米（6.5英尺）捕获一个完整的360°圆顶图像。同时，激光扫描仪记录每2毫米（0.08英寸）的横截面数据。所有这些都合并为单个云创建3D模型。结果是直接映射功能，而无需复杂的后处理观察到的数据，节省时间和资源。

机会世界
徕卡珀加索斯:两个和移动映射过程ss have revolutionised the world of surveying. There are huge benefits for using mobile mapping systems, especially for infrastructure projects such as the M6 motorway. Access to the motorway is left clear, with no need to close off roads, as the Pegasus:Two acts in the same way as any other public vehicles, only it is collecting 3D geospatial data. Safety is drastically improved using mobile mapping because surveyors no longer need to stand in the road working under time pressure in critical environments to complete projects. All data is now captured from the safety of a vehicle travelling the same speed as the rest of the traffic.

收集的数据的速度和准确度so improved. Using traditional static laser scanning methods, two teams would spend several months to survey the highway and other assets along the 17 kilometre (10 mile) section of the M6. Using the Leica Pegasus:Two, Severn Partnership provided their customer with detailed deliverables in just two weeks. Reducing the speed of data collection means a cost saving for customers of 60 percent when compared with the traditional static laser scanning. Also, larger circumferences were covered, giving more accurate, efficient and complete data using combined LiDAR and photogrammetry.

“在Severn Partnership，我们了解需要投资最新技术，以便继续为客户提供最高水平的服务。Pegasus：两个是市场上最准确的移动映射单元之一，并且不需要安装在其前面的调查地面控制。“我们将在移动车辆，汽车，货车，公路车，手推车和其他车辆之间转移它，以扫描所有地形的数据。”

The world of surveying is changing and the combining and marriage of multiple technologies has been a giant leap, one which Severn Partnership has openly embraced and serenely adopted for their customers. Mobile mapping has provided a rapid data capture solution for their customers, minimising cost, reducing safety risk and maximising value.
