The faster road to mobile data capture

Author: Tamara Stakic, Marketing Manager- 大洋洲利卡（Leica Geosystems）

Veris Australia（Veris）是澳大利亚最大的测量和空间信息服务提供商，拥有20个办事处的近500名专业人士，对为大型多面项目提供服务并不陌生。该公司有一个往绩可以追溯到60年以来，可以在全国范围内以跨越能源，采矿和资源，住宅，商业和零售业的国家规模交付项目，仅举几例。

To deliver market-leading planning, design, surveying and spatial solutions Veris recognises that digital and spatial technology innovation increases value, enhances the quality and boosts productivity for project delivery. Access to the latest technology allows the company to provide the best quality data and services to their clients as part of their 3D Spatial services.

Going mobile: A case for Leica Pegasus: Two

Recently the Veris Digital and Spatial team reached out to Leica Geosystem Australia and New Zealand to upgrade their existing Mobile Laser Scanning (MLS) systems to increase processing efficiency with the newLeica Pegasus:Two Ultimate Mobile Sensor Platform. “With the recent improvement of trajectory processing and image acquisition, the Leica Pegasus: Two Ultimate Mobile Sensor Platform was the perfect mix of data quality and functionality for Veris,”said Brad Chambers, National MLS Manager at Veris.“The high-quality image collection adds another aspect to MLS that our client’s value.”

Since acquiring two Leica Pegasus: Two Ultimate systems, Veris have deployed the solution for projects within highly trafficked roads or freeways that are typically more challenging and time-consuming to survey using methods such as total stations, GNSS or Terrestrial Laser Scanning.

“We believe with the improved efficiencies we are now 50 per cent more efficient on the post-processing of the point cloud data. We’ve become more productive as we no longer need to deploy an experienced operator to site, something we’ve had to do for many years - saving us time and the need to fly to site,”钱伯斯说。

Veris凭借其两个新的Leica Pegasus：两个终极系统和改进的图像，可以捕获道路和铁路前建筑前的破坏，资产管理，裂纹检测和机器学习应用程序。Leica Pegasus：两个最终结合了两个背对背摄像机，创建了24 MP 360度图像，该图像校准了LiDAR Profiler数据，并允许在各种照明条件和车辆速度下捕获。摄影测量和图像质量令人印象深刻，十二兆像素和板载JPEG压缩。

While there are major productivity gains that come with deploying the Leica Pegasus: Two Ultimate on projects such as capturing high-density 3D point cloud data along with high-resolution imagery without needing to step outside your vehicle, there are safety benefits such as eliminating danger zones and significant health and safety risks by capturing data without the need to close roads, stop trains, interrupt service networks, and the need to survey at night.

One of the applications the Leica Pegasus: Two Ultimate excels at due to the high-resolution imagery is pavement and road inspection. Veris put this to the test on a recent project involving a 3-kilometre-long section of the freeway for pavement monitoring, to enable the assessment of flexible pavements in highly reactive soil types. The main challenge with this project is that the main section of the motorway was lowered approximately 10-18 metres below ground level in a GNSS-denied zone. With adequate survey control and as-built information (static structures at 20-meter intervals) Veris was able to adjust the point cloud to <5mm of the survey data both horizontally and vertically.

点云提供了现实世界的全面视图，并允许Veris团队提取数据以满足客户需求，而无需返回网站以收集数据 - 这种细节级别不可能在相同的时间内捕获使用传统的调查实践。在这种情况下，Veris的客户端能够使用捕获的数据来评估在放置沥青的最后一层之前是否需要进行任何分析，以确保正确的层厚度。

Onboarding the Leica Pegasus:Two Ultimate

评估Veris移动映射单元的选项时，最重要的方面之一是强大的本地供应商支持，将系统适应不同方案的灵活性以及用于图像和点云捕获的集成解决方案 - Veris需要一个解决方案，可以帮助他们帮助他们提供详细的点云和高质量的图像。

Other aspects that made the Pegasus:Two Ultimate the clear standout is that the system does not need to be installed on a specific vehicle. It can fit the standard roof racks and the ability to run the equipment without a power connection to the vehicle, as the system does not require wheel odometers, so it saves time on set up.

Veris国家MLS经理Brad Chambers紧密参与了决策，描述了他们第一次将系统带到现场。“The Leica Pegasus: Two Ultimate was easy to set up on a vehicle, with the connection to the system by Wi-Fi using a Veris owned laptop. We were able to send the equipment to the site and have a couple of surveyors (both had not operated MLS before) install the equipment under an experienced operator’s instruction via screen sharing and Webex. A short mission plan was reviewed before the data capture, then a review of the data by the experienced operator before completion.”

And when it comes to getting trained on the Leica Pegasus:Two Ultimate?“For us the training phase of using the Leica Pegasus: Two Ultimate involved the post-processing of missions through to adjustment of trajectories, point clouds and imagery. During a two-day session, we were able to train 12 staff from all states and territories in Australia via Webex. Although this would have been usually done onsite, the solution was excellent given COVID restrictions,”钱伯斯说。

When asked about what piece of advice they would give to peers considering adding a mobile mapping solution to their fleet, Brad reflected on the need for the operator to prepare in advance for the project and consider all possible scenarios,“as with all technology, there are things that you need to be aware of, MLS is a very challenging surveying activity, and requires an vast amount of effort and understanding of how point clouds and images react in different environments. The Leica Pegasus: Two Ultimate is no different and still requires the operator to think about every scenario; fortunately, the Leica Pegasus:Two Ultimate makes this easier with its post-processing workflow.”

The road ahead for Veris

The efficiency gains are also getting noticed by clients. “我们已经看到澳大利亚东海岸的移动地图项目有所增加，我们的客户对高度详细的数据和令人印象深刻的图像感到满意。墨尔本的一个关键客户在我们能够将Pegasus整合到的周转时间中感到惊讶：两个终极数据与Leica ScanStation P40数据，”钱伯斯说。

为真实survey-grade准确的数据from Pegasus: Two Ultimate creates opportunities to undertake additional and larger projects and grow their service offering. Veris is exploring how the imagery can be leveraged by integrating the multiple pavement cameras for automatic crack detection using machine learning; this will give Veris an additional industry in road analysis that can be leveraged with the Leica Pegasus:Two Ultimate.

As with any new technology, Veris continues to review their outcomes to ensure that delivery to the end clients is exceptional – a commitment to quality is deeply integral to Veris.Find out more about Veris Australiahereand connect with布拉德·钱伯斯on LinkedIn.
