捕获英格兰高速公路地区的快速准确数据

Sun Hill测量和工程有限公司是一家专业的土地测量和工程公司，拥有30多年的经验，重点关注整个英国的土木工程领域。Sun Hill仅通过专业知识的投资组合提供最高质量的服务，为传统和最先进技术的独特组合带来了现代的测量方法。

在此期间，与Leica Geosystems紧密合作了20多年，并大量投资于Leica Geosystems产品和解决方案；亚搏彩票手机版下载Sun Hill对Leica Pegasus进行了巨大的资本投资：2015年8月两次。从Leica Geosystems采用这项新的移动映射技术是一家不断发展的公司投资的重要一步。考虑到他们的客户群和聪明的工作方式，随着对高速公路基础设施维护的压力越来越大，它使对Leica Pegasus的投资：两个是必要的。

Highways England Area 3 project
Soon after this investment in mobile mapping technology, Sun Hill was approached and commissioned by Kier to survey 119 sites on behalf of Highways England Area 3. Area 3 is Highways England’s second largest network carrying around 10 per cent of the country’s overall traffic flows. It includes the M27, M3, M4, A3, A303 and the Hindhead Tunnel and provides the main link routes between several major towns and cities including Oxford, London, Reading and Swindon in the north, and Bournemouth, Southampton and Portsmouth in the south.

Challenge
大规模项目需要对车道和边缘进行详细的地形调查，每项调查的设计和未来更换和安装道路标牌的长度为600m，以在道路上的整个梯度上更清晰可见。该设计的地形调查功能包括对车道范围，路标，碰撞障碍，通道，路缘，沟渠，缘堰，边缘堰，边缘水平，铁件框架，签名位置，交通环，高架电缆，电气盒，电气盒，电气盒，电脑，电气盒，电盒，电箱，电路架，电路架，电路架，电路架，电路架，电路架，电路架，电路架，电路架，电路架，电路架，电路架，电路，电箱，电箱，栏杆，围栏，台阶，桥拱形水平和码头位置。

To survey these sites traditionally is a long and protracted operation using laser scanners, total stations and GPS, to collect thousands of points of data per day. Typically, this would take a surveyor around 2 days per site to complete in the field. Also to survey this many sites would have required 119 individual traffic management installations. With a project of this size, there is a significant health and safety risk associated to all involved, to personnel being both in the carriageway and in the verge during all times of the day and night. A safer and more cost effective method was needed to deliver the project on time and in budget.

通过移动映射捕获数据
Leica Pegasus：两个和移动映射过程彻底改变了测量世界。使用移动映射过程，Leica Geosystems的技术为Enail 3 Highway England项目提供了巨大的好处。进入所有站点的访问均未清除，没有路上的道路封闭，就像Leica Pegasus：在收集3D地理空间数据时，两种行为与任何其他公共车辆相同。总的来说，测量师使用Leica Pegasus进行了超过13,000公里的行程：每秒收集数百万分。由于不需要流量管理，因此网络没有中断，因此流量流如正常一样继续。使用移动映射的调查人员的安全性得到了很大的改善，因为在道路上不需要测量人员或交通管理人员，因为所有数据都是从车辆安全中捕获的。虚拟测量师能够从点云创建传统的地形调查。移动映射为KIER提供了快速的数据捕获解决方案，节省了时间，通过将200场日项目减少到12天的移动映射，从而减少了安全风险并最大程度地提高了价值。

结果和好处
As a result of using the Leica Pegasus:Two, all 119 sites were surveyed in only 12 days, with no traffic management, allowing processing and extraction to be undertaken from the safety of an office environment. Furthermore, all 119 sites were surveyed and delivered to Kier a week before the final deadline, thanks to the speed of accuracy delivered through using the Leica Pegasus:Two. The total project took 118 days to complete including field operations. Sun Hill was able to deliver this project with less than 20mm absolute accuracy. The surveys were then delivered in a staggered program, allowing sites to be prioritised and enabling some sites to be delivered earlier than others.
