数据处理和生产CAD和其他可交付成果是否会使您头疼？

Reality Capture experts know that capturing data is just one step in the process. Processing, managing and delivering data are part of the workflow. Processing and producing CAD and other deliverables can sometimes be the most time-consuming parts of the workflow.

Tim Beach, Chartered Geomatics Surveyor and Measured Building Specialist from Hollis, has been relying on laser scanning in the U.K. since 2003. Hollis is a leading firm of independent real estate consultants with 24 offices in the U.K., Ireland and mainland Europe. Beach is based within the Measured Survey team and is responsible for AEC level-detail projects.

Within his role, he gets to test hardware and software to ensure the solutions are as efficient as possible for their clients. Beach has successfully incorporated laser scanning into existing measured building survey workflows at Hollis.

在其25个服务产品中，Hollis的测量服务集成到其他几个服务中，例如机械，电气和管道工程（MEP），在该机械，电气和管道工程（MEP）中，团队对植物和环境使用激光扫描，需要修订建模进行冲突检测练习。该单元对其他应用程序使用激光扫描，例如光权（ROL）分析的权利（ROL）来检查新开发项目的影响，项目管理对现有建筑物的翻新和重建。

Hollis owns several Leica Geosystems equipment, including:

• 2Leica ScanStation P40s
• 3Leica RTC360 3D Laser Scanners
• 2Leica TS16和4 Leica TS12 Total Stations
• 3Leica Builder 亚博5分钟快三Total Station
• 2Viva GS16 GNSS和4 Viva GS08 plus GNSS
• 4Leica Cyclone寄存器和Cyclone REGISTER 360, 2Leica Cyclone模型, 12对AutoCAD CloudWorx, 12JetStream Connectors, 2 Cyclone PUBLISHER PRO.

“Hollis has invested quite heavily in Leica Geosystems equipment in recent years. Having tested various hardware and software providers, we chose Leica Geosystems. We found Leica Geosystems gave us the solution that fits best into our business model. We have a number of ScanStation P40’s, total stations and GPS for control and putting our surveys in the correct location,” said Beach.

Laser scanning a 180,000-square-feet building

The challenges of laser scanning an 11-floor 180,000 sq.ft. building in central Birmingham, U.K., go beyond the building itself, including finding locations which provided visible access to each face of the building in an already congested area. Hollis opted for laser scanning given the scale of the building, its complexities, and the client timescales and deliverables.

要扫描每个楼层的每个房间，Hollis必须与所有租户协调访问安排。“Laser scanning in conjunction with accurate survey control allowed us to move around the building, scan what we needed to in the areas we had access to at that time, knowing that we would be able to register the captured scan data together at the end, and be confident that we would be able to get the correct result,”said Beach.

The deliverables requested by the client included standard 2D CAD information of floor plans, elevations and cross-sections. During the project, the client required additional information, including structural soffit and slab details in various locations, a full topographical survey of the immediate surroundings, façade deviation reports and monitoring work.

数据抓取

由于截止日期的紧迫，霍利斯（Hollis）用Leica Scanstation P40部署了两支球队，并在短短五天内完成了调查。需要八天的现场捕获建筑物的内部，再加上一天以安装围绕该物业的调查控制并进行外部激光扫描。该团队充满信心地收集了数据，而无需过度调查控制，从大约1,500个扫描位置产生了90 GB的原始数据。Viva GS08加RTK GNSS用于地理参考站点周围的多个点，以将数据转换为军械调查网格和数据。

Processing Data

Hollis began registering the captured scan data after the first site inspection day. The two survey teams on-site sent the collected raw data at the end of each day to the local office to begin import and registration. All registration elements were carried out during the day and auto alignments left to process overnight. This workflow minimised the processing time and permitted the team to start the CAD work early on. In total, Beach’s team took six days for registration, resulting in a final database of 259 GB.

Beach和他的团队使用旋风登记处注册，并在本地控制和云中注册所有扫描。Cyclone寄存器允许团队将注册分为逻辑零件，并将它们组合起来以生成最终的主数据集。

"We found that cloud-to-cloud provided the greatest flexibility in the site work and the registration of a building with such complex geometry. Being able to register your data together, combined with the P40 with a dual-axis compensator, ensures we are confident that the data we are producing is correctly orientated and we don’t have any issues downstream. […] Cyclone REGISTER gave us an incredibly flexible approach to how we undertook the registration,”said Beach.

Managing Data

霍利斯（Hollis）在分布在多个办公室的测量服务团队中有30名员工，他们可能在任何给定时间都需要任何给定项目的数据。为了为客户生成可交付成果，跨区域团队使用高性能流和集中式项目平台合作，通过内部和外部网络访问数据-Leica Jetstream。使用此简化的点云访问Hollis测量的调查专家可以在CAD应用程序中实时导入和渲染全密度点云数据，并与各种利益相关者共享JetStream Viewer文件。使用这种方法，房地产咨询公司简化了项目的合作。

"The use of Leica Jetstream has allowed us to host our data centrally in London, where everyone can access. If our regional offices undertake a scanning project, they can upload to the JetStream Server overnight, opening up the data to everyone else. For other teams who are not power users of scan data but occasionally need to use the data, we can host and archive their project's data,"said Beach.

Using Leica JetStream allowed the team to disseminate the final data set amongst various teams in various locations to complete the project on time and budget.“JetStream enabled us to complete the project in the most efficient manner and as accurately as possible.”said Beach.

传递数据

测量员生成a great amount of data using laser scanning that is captured, processed and managed to provide actionable data that supports decision-making.

Leica Truview是Hollis测量团队的协作工具，依靠共享点云数据和设计模型。Tim团队中Truview的众多用途之一是作为“演练”型号的问答工具，并远程可安全地检查拥挤的环境。

“LeicaTruView provides a location-based view of data from the sites. We use it to produce the deliverables using all information available – not just relying on slices in CloudWorx where features can be missed. For the building project in central Birmingham, our team could split the data logically by building and by floor. TruView allows viewers to measure, add geometry, incorporate hot links and embed geotags for asset management needs,”said Beach.

Full end-to-end solution from data collection to delivery

Using a complete reality capture workflow from Leica Geosystems, Hollis produced deliverables of floor plans, sections, and elevations for its client in the most efficient manner. Through re-use of previously-collected data, the team could accommodate the clients’ additional requirements very quickly. Geared with JetStream surveyors saved time by loading and accessing data from one central location, helping to deliver the project on time and budget.
