The faster road to mobile data capture

Author: Tamara Stakic, Marketing Manager- Leica Geosystems, Australasia

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，在全国范围内以跨越能源，采矿和资源，住宅，商业和零售业为单位的国家规模上交付项目，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

最近,真实挖ital 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,”said Chambers.

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Ultimate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.

Leica Pegasus的应用之一：由于高分辨率图像是人行道和道路检查，因此两个最终的效果很高。Veris对最近的一个项目进行了测试，该项目涉及高速公路的3公里长的路段进行路面监控，以评估高度反应性土壤类型中的柔性路面。该项目的主要挑战是，高速公路的主要部分在由GNSS污染区域的地面降低了约10-18米。借助适当的调查控制和井井有条的信息（以20米的间隔静态结构），Veris能够水平和垂直范围调整点云<5mm。

云提供一个全面的观点的real world, and allow the Veris team to extract data to meet client needs, without needing to return to the site to collect data - this level of detail could not have been captured in the same amount of time using traditional survey practices. In this case, Veris’ client was able to use the data captured to assess if any profiling is required before the final layer of asphalt is placed to ensure correct layer thickness.

Onboarding the Leica Pegasus:Two Ultimate

One of the most important aspects when evaluating options for a mobile mapping unit for Veris was strong local supplier support, flexibility in adapting the system to different scenarios and an integrated solution for imagery and point cloud capture – Veris needed a single solution that would help them deliver detailed point clouds and high-quality imagery.

使Pegasus的其他方面：两个最终的明确脱颖而出的是，该系统不需要安装在特定车辆上。它可以安装标准的车顶架，并且能够在没有与车辆的电源连接的情况下运行设备的能力，因为系统不需要车轮的气光仪，因此可以节省设置时间。

Brad Chambers, National MLS Manager at Veris was closely involved in the decision making, describes their first time taking out the system to site.“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,”said Chambers.

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,“与所有技术一样，您需要注意的是，MLS是一项非常具有挑战性的调查活动，需要大量的努力和对点云和图像在不同环境中的反应方式的理解。Leica Pegasus：两个终极的人没有什么不同，仍然要求操作员考虑每种情况。幸运的是，Leica Pegasus：两个最终的工作流程使其后处理的工作流程更加容易。”

The road ahead for Veris

客户也注意到了效率的提高。“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，”said Chambers.

For Veris the survey-grade accurate data available 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 withBrad Chamberson LinkedIn.
