Veris Australia(Veris), the largest 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.

为了提供市场领先的计划，设计，测量和空间解决方案，Veris认识到数字和空间技术创新可以提高价值，从而提高质量并提高项目交付的生产率。访问最新技术使该公司可以作为其3D空间服务的一部分为客户提供最佳的质量数据和服务。

Going mobile: A case for Leica Pegasus: Two

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。“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.“高质量的图像集合为客户的价值增加了​​另一个方面。”

自从获得两个Leica Pegasus：两个最终系统以来，Veris已在高度运输的道路或高速公路内部署了解决方案，这些解决方案通常更具挑战性，并且使用诸如Total Station，GNSS或陆地激光扫描等方法的调查更具挑战性和耗时。bob apple

“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。

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.

虽然部署Leica Pegasus的生产率有很大的提高：两个终极的项目，例如捕获高密度3D点云数据以及高分辨率的图像而无需走出车辆，但存在安全益处，例如消除危险通过捕获数据而无需关闭道路，停车火车，中断服务网络以及在夜间进行调查的情况，区域和重大的健康和安全风险。

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捕获了澳大利亚阿德莱德高速公路的3公里长的一段，以进行路面监控。

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.

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?“对我们来说，使用狮子般的飞马的训练阶段：两个最终涉及任务后处理，以调整轨迹，点云和图像。在为期两天的会议上，我们能够通过Webex培训来自澳大利亚各州和地区的12名员工。尽管通常会在现场进行，但考虑到联想限制，该解决方案非常好。”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,“和所有技术一样,有你的东西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. “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,”钱伯斯说。

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.

与任何新技术一样，Veris继续审查其成果，以确保向最终客户交付是非凡的 - 对质量的承诺是Veris的重要组成部分。Find out more about Veris Australiahereand connect with布拉德·钱伯斯on LinkedIn.
