维持丹麦高速公路推动运营效率

作者：西蒙·霍尔

A national road network is one of the most important pieces of infrastructure any country will ever built and maintain. Ensuring that these public highways are kept to the highest possible standard results in a dramatic increase in public safety, however it is possible for some roads are not kept to the standards required.

超过11000公里的双车道公路,阿龙g with several thousand more smaller roads, the Danish Road Directorate (Vejdirektoratet) contracted Getmapping after a tendering process to survey the road state network. High density terrestrial point cloud data and matching high resolution panoramic imagery would be collected using the state-of-the-artLeica Pegasus：两个移动映射终极设备。

Getmapping PLC is a leading global provider of geospatial data and survey solutions. They have over 20 years’ experience in the capture and delivery of high-resolution aerial imagery, LiDAR, digital mapping and web-based services across Europe and Africa. Their goal is to enable the timely and cost-effective delivery of geospatial data, creating digital replicas of the world. Getmapping collects, transforms, stores and delivers scalable geospatial data, mapping and modelling solutions to enable better decision making. By creating true digital replicas of the environment, their aim to empower their customers and partners to create solutions to the challenges facing their business and the planet.

Vejdirektoratet, or the Danish Road Directorate, is responsible for the national road network of Denmark, which comprises motorways, several main roads and many of the country’s bridges. They create coherence for the many road users who use the Danish state roads every day. They accomplish this by developing, planning and constructing Denmark’s infrastructure and bind the country together. It requires solutions that balance mobility, the environment and road safety.

About the Project

Despite having some of the safest road in Europe with only 30 deaths per million inhabitants in 2020 , the goal of Vejdirektoratet was to scan the 11,000 km of road networks across the country using the Leica Pegasus: Two Mobile Mapping Ultimate solution, enabling them to collect high density terrestrial point cloud data and matching high resolution panoramic imagery.

“这是一个令人兴奋的获取图表的项目。丹麦是我们的新市场，扩大了我们作为西北欧洲航空和移动地图服务领先的领先供应商的领域。”

Within 6 months of the contract award, Getmapping were scheduled to have delivered a full dataset of 3D laser point clouds and 360-degree photos to the Danish Road Directorate, covering all state roads and their immediate surroundings.

Challenges

在该项目中，GetMapping团队面临着一些挑战。该项目的规模是GetMapping有史以来最大的移动映射项目之一，可覆盖11,000多行公里。广泛的数据处理和分类要求，包括图像匿名，4类LiDAR分类以及时间标准，重新定点的获取映射以在不到6个月的时间内交付完整处理的数据集，包括数据捕获。

“Covid19 and Brexit are already the ‘new normal’ at Getmapping and are included and considered in all our activities. The biggest challenge for this project was the tight deadline to capture, process and classify such a large amount of data in such a short amount of time: something that has never been done before! The project was made possible by identifying the duration and dependence of each task and dedicating adequate team management to each one of them. ”

Despite the challenges – the scale, extensive data processing and short execution period, Getmapping delivered the clients expectations:

• Highly efficient data capture, which meant the data only had to be captured once to meet the project specifications
• 每天捕获的数百公里公里确保所有映射均在项目开始日期的3个月内完成
• The mobile mapping data, including classifications was processed and delivered in phases, providing usable and relevant information for immediate consumption and analysis
• The full data set was delivered within the required 6 month deadline

Mobile mapping solution

与Leica Pegasus：两个终极移动映射解决方案，GetMapping能够将激光扫描仪与GNSS接收器，IMU和DMI结合使用，并使用安装在车辆上的摄像头获得准确而精确的空间数据。

The innovative mobile sensor platform captured the required point cloud and imaging data. The multi-sensor approach allowed Getmapping to increase their ROI by collecting more data in one pass, decrease their time in the field and
使用相同的资源产生更高的结果。现实捕获亚博ag真人规律解决方案完全独立于车辆，使其成为多个应用程序中有能力的解决方案，而无需将用户限制在道路和铁路上。

Getmapping only needed to capture the data once surpassing the project specifications with respect to point density and expected data accuracy, keeping their employees safe and decreasing their time in the field. The Pegasus:Two captured
the full 360° spherical view imaging and LiDAR together, meaning Getmapping would not have to return to a specific project site once the data had been captured.

A view to the future

Leica Pegasus：两个最终是该项目的最佳选择。使用此移动映射系统，花费的时间较小，并且比任何其他测量方法更具成本效益，才能达到这种细节和准确性。数据还提高了操作效率，使Vejdirektoratet员工能够从办公室进行视觉检查和测量，从而减轻现场访问的健康和安全风险。新数据还将使他们能够在各个领域开发全新的方法和应用程序。

“Getmapping have a strong focus on collaboration. For projects like this, the benefits of this consultative approach went beyond the provision of best of breed technology, to how we collectively provided our customer with high quality business insights, effectively and efficiently.”

Getmapping are now actively marketing for other bespoke survey opportunities using the Pegasus:Two, and this project showcases the extent of the surveying that they can provide.

Over the last 12 months they have worked with a rapidly increasing number of customers who are looking for a faster,safer, cost effective alternative to traditional topographical survey techniques, and their Mobile Mapping solution is being used in a variety of new and innovative ways including Highways Planning, Asset Management, Monitoring Changes, Parking Apps, 3D Modelling and Artificial Intelligence.
