Revolution in motion

Severn Partnership努力使用最新且具有创新的解决方案为其客户提供服务。自从收购Leica Pegasus以来，总部位于英国什鲁斯伯里的特许地理（土地）测量师二人公司（Two）将这种尖端技术用于客户的各种基础设施和建筑项目。凭借这项新技术的好处，Severn Partnership渴望传递这项新技术的好处，很高兴被委托调查M6的一部分，以收集重要资产，以制定其风险和维护策略计划。对Midlands地区M6的17公里（10英里）部分进行了完整的详细调查，包括车道限制，碰撞障碍，资产，路标和SOS电话，中心线，中央预订，桥梁结构和灯柱。需要进行调查以改善高速公路的整体布局，以确保可以维持定期维护检查，以消除锅孔，并为驾驶员保持光滑，安全的道路表面。

测量M6高速公路的一部分的挑战是巨大的，关闭繁忙高速公路的这一部分是不可行的。访问的限制是一个严重的问题，因为在收集数据的同时，高速公路需求保持开放。同样，在短时间内在高速公路上进行调查的大量资产也很重要。使用传统的总站仪器执行该项目将是使用Pegasus的两倍：两次，每天收集数千个调查数据。从逻辑和实践上讲，测量师在高速公路中间收集数据是危险的。项目的总体成本随着整个项目周期的积极流量管理的需求而增加。需要更有效的收集过程。

映射M6高速公路的最佳解决方案
Severn Partnership used mobile mapping – the process of collecting 3D geospatial information from a moving vehicle – to quickly and accurately provide customers with 2D and 3D CAD plans as well as fully registered point clouds of the entire route section. These point clouds are millions of individual coordinates measured on anything the laser reflects off, such as bridges and roads and can be used to extract even more information, such as GIS datasets. The device is attached to the roof of a moving vehicle and seven cameras then capture a full 360° dome image every 2 metres (6.5 feet). Simultaneously, a LiDAR scanner records cross section data every 2 millimetres (0.08 inches). All this is combined into a single cloud creating a 3D model. The result is a direct mapping of features without the need for complex post-processing of observed data, saving time and resources.

A world of opportunity
Leica Pegasus：第二和移动映射过程彻底改变了测量世界。使用移动映射系统有很大的好处，特别是对于M6高速公路等基础设施项目。通往高速公路的通道是清晰的，无需像Pegasus那样关闭越野：两种行为与其他任何公共车辆相同，只有它收集了3D地理空间数据。使用移动地图大大提高了安全性，因为测量师不再需要在关键环境中在时间压力下工作以完成项目的道路。现在，所有数据都是从车辆的安全性捕获的，其行驶速度与其他交通相同。

The speed and accuracy of the data collected is also 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.

“At Severn Partnership, we understand the need to invest in the latest technology in order to continue to offer the highest level of service to our customers. Pegasus:Two is one of the most accurate mobile mapping unit on the market and does not need survey ground control installed ahead of it, ” said Mark Combes, managing director at Severn Partnership. “We will be transferring it between mobile vehicles, cars, vans, roadrailers, trolleys and other vehicles to scan data across all number of terrain.”

测量的世界正在发生变化，多种技术的结合和结合是一个巨大的飞跃，塞文伙伴关系公开接受和宁静地采用了这一飞跃。移动映射为客户提供了快速的数据捕获解决方案，最大程度地降低了成本，降低了安全风险并最大化价值。
