Laser Scanning on the go

随着世界人口的增长和建筑和基础设施建设的全球变化，我们需要记录这种增长和变化的需求。这个新概念被称为可穿戴现实捕获传感器系统，它塑造bob综合app赌博了测量专业人员如何理解和塑造世界中的世界。Leica Pegasus：背包是作为这一代新的可穿戴现实捕获传感器系统的一部分发明的，以应对日益增长的全球变化。bob综合app赌博Prisma集团是第一家利用Pegasus：Backpack的公司。

Based in the Netherlands, the Prisma Group consists of three companies: Prisma Meten, Prisma Geocensus and Prisma Van Steenis. The company has a variety of specialities including survey (rail, infrastructure, utility), industry (offshore and onshore), GIS, hydrography, geodetic measurements, 3D laser scanning, monitoring and mobile mapping.

The Prisma Group has always been a brand advocate of Leica Geosystems, relying on the quality products that generate quality services. One of the Prisma Group’s goals is to develop the international market. With rapid progress in the field of 3D laser scanning, the Prisma Group was keen to work closely with Leica Geosystems to achieve its goal and to become No. 1 in the field of scanning.

Concentrating on scanning rails
通过合作伙伴关系,棱镜范圣eenis was the first 3D specialist in the Netherlands that produced a 3D scan with the Pegasus:Backpack at the rail tracks of Pernis Rotterdam, Netherlands. Leica Geosystems was approached by Prisma Van Steenis in November 2015 to help with this challenging project. The project came about as it was commissioned by the government for a rail contractor to firstly verify the principles of procurement and then to assess what materials, such as ballasts, sleepers and rails, were present. Prisma Van Steenis were commissioned to carry out the rail project.

The project scope entailed the scanning of the position and height of the rail tracks because the contractor was looking to renew his contract and was keen to impose the new alignment of the railway track. Before any measurements could be taken, there was an initial analysis of the project interfaces and overlaps, and the risks carried out with the scan data and the 360-degree shots. The area that was scanned was a yard with numerous tracks and switches, containing 1.5 kilometres of industrial freight, which was in full use by several carriers and companies. The complete 3D scan will be used for reverse engineering, to help with lay-plans, ballast volumes and profiles. The captured 3D data can be used to build a reliable design of a new railway track layout, delivered as a 3D model, and can also be used for BIM and quantity determination.

在困难空间中的流动性
在该项目期间试图捕获现实数据的同时，在铁路环境中有许多挑战。从低悬挂的电线到火车车周围的狭窄空间，在这种环境中，经典的测量方法可能非常有限。在进行铁路项目的同时，Prisma Van Steenis必须在使用院子的同时进行测量，因此，碰撞的真正风险和个人健康和安全的风险很高。根据法律，风险区域（铁路轨道）不是测量师的可访问区域，通常被禁止进行检查。Prisma Van Steenis需要一个安全，快速，准确的解决方案，以收集该扫描项目所需的点云和360度图片。需要迅速收集调查，以减少成本和交货时间。

The deployment of the Pegasus:Backpack provided numerous advantages over traditional methods for the Prisma Group. The surveyors were a lot safer on the tracks and ran much less risk to their health because they did not have to enter the risk area. In addition to this, the surveyors did not have to perform any measurements during nightfall, which is a hazard in itself with limited visibility causing many hazards of its own. The Pegasus:Backpack was the perfect solution. Distances could be measured without entering dangerous areas with maximum effect. With one measurement from the Pegasus:Backpack, the surveyor was provided with the correct, current and complete information on the same day. The quality of the measurements from the Pegasus:Backpack are highly accurate and best in class.

The results of the project were compared with traditional terrestrial surveying, which took several days to complete, and the results from the Pegasus:Backpack were very impressive. The differences between the Backpack-scan and the digital measurements are about 3 centimetres on an absolute level, and the relative results are even better (mm level). The captured 3D data can be used to build a reliable design of a new rail track layout. The newer technology also allowed the measurement professionals to conduct the entire survey in three hours, that would normally take five days. There was also a cost saving of nearly 50 percent for the contractor. The advantage of scanning is that you capture the entire situation, so any forgotten detail can be obtained from the point cloud at a later date if necessary.

Prisma总监Klaas debob综合app赌博 Weerd说：“使用可穿戴现实的捕获使我们能够实现与传统测量技术相比的许多好处。”“有了Leica Pegasus：背包，可以到达铁路场的每个地方。我们也不必实施额外的安全措施，因为我们不需要进入高风险领域：我们可以简单地从安全距离捕获数据。最后，由于无错误的数据获取，我们在基线调查中看到了大量节省的时间，这将使我们能够准确监视将来设计的任何更改。”
