Veris澳大利亚(真实),大st provider of surveying and spatial information services in Australia, with almost 500 professionals located across 20 offices, is no stranger to servicing large multi-faceted projects. The company has a track record going back 60 years of delivering projects in private and public sectors on a national scale spanning across energy, mining and resources, residential, commercial and retail industry just to name a few.

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.

移动移动：雷卡·皮卡斯（Leica Pegasus）的案例：两个

最近，Veris数字和空间团队与Leica Geosystem Australia和New Zealand接触，以升级其现有的移动激光扫描（MLS）系统，以提高新的处理效率Leica Pegasus：两个终极移动传感器平台. “随着轨迹处理和图像采集的最新改进，Leica Pegasus：两个最终的移动传感器平台是Veris的数据质量和功能的完美组合，”Veris国家MLS经理Brad Chambers说。“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.

“我们相信，随着效率的提高，我们现在在点云数据的后处理方面提高了50％。由于我们不再需要部署经验丰富的操作员来站点，我们已经变得更加富有成效，这是我们多年来必须做的事情 - 节省了我们的时间和飞往现场的需要，”said Chambers.

With their two new Leica Pegasus: Two Ultimate systems and improved imagery, Veris can capture projects for road and rail pre-construction dilapidation, asset management, crack detection and machine learning applications. The Leica Pegasus: Two Ultimate incorporates two back-to-back cameras creating a 24 MP 360-degree image calibrated to the LiDAR profiler data and allows capture in a variety of lighting conditions and vehicle speeds. Photogrammetry and image quality are impressive with twelve megapixels and onboard JPEG compression.

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.

Veris captures a 3-kilometre-long section of the freeway in Adelaide, Australia for pavement monitoring.

Point clouds provide a comprehensive view of the 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.

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.

Brad Chambers, National MLS Manager at Veris was closely involved in the decision making, describes their first time taking out the system to site.“ Leica Pegasus：使用Veris拥有的笔记本电脑通过Wi-Fi连接到系统的连接，很容易在车辆上设置两个终极。我们能够将设备发送到网站，并通过屏幕共享和Webex在经验丰富的操作员的指导下安装了几个测量师（均未操作MLS）。在数据捕获之前对简短的任务计划进行了审查，然后在完成之前由经验丰富的操作员对数据进行审查。”

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.

当被问及考虑在其舰队中添加移动映射解决方案的同行提供什么建议时，布拉德反映了操作员提前准备项目的需要，并考虑所有可能的情况，并考虑所有可能的情况，“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.”

前进的道路

The efficiency gains are also getting noticed by clients. “We’ve already seen an increase in mobile mapping projects on the east coast of Australia and our clients are happy with the highly detailed data and impressive imagery. A key client in Melbourne was amazed at the turnaround time that we were able to achieve to integrate the Pegasus: Two Ultimate data with the Leica ScanStation P40 data,”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.了解有关Veris澳大利亚的更多信息这里并与之联系Brad Chambers在LinkedIn上。
