Is data processing and producing CAD and other deliverables giving you a headache?

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激光扫描仪
• 2Leica TS16和4个Leica TS12总站亚博5分钟快三
• 3Leica Builder Total Stations
• 2Viva GS16 GNSS和4个Viva GS08加GNSS
• 4Leica Cyclone REGISTER和旋风寄存器360，2Leica Cyclone MODEL，12CloudWorx for AutoCAD，12JetStream Connectors，2Cyclone 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海滩说。

激光扫描180,000平方英尺的建筑物

激光扫描11楼180,000平方英尺的挑战。在英国伯明翰中部建筑物，超越了建筑物本身，包括找到可见的位置，可见到已经拥挤的地区的建筑物面孔。鉴于建筑物的规模，其复杂性以及客户时间表和可交付成果，Hollis选择了激光扫描。

扫描每一个房间的每一层,霍利斯had to coordinate access arrangements with all tenants. “激光扫描与准确的调查控制能力使我们能够在建筑物周围移动，扫描当时我们可以访问的区域所需的东西，知道我们能够在结束时一起注册捕获的扫描数据，并且确信我们能够获得正确的结果，”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

在第一个现场检查日之后，Hollis开始注册捕获的扫描数据。现场的两个调查团队在每天结束时将收集的原始数据发送给当地办公室开始进口和注册。所有注册元件均在白天进行，并且自动对准剩下的一整夜。此工作流程最大程度地减少了处理时间，并允许团队尽早开始CAD工作。总体而言，Beach的团队花了六天的时间进行注册，最终数据库为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。

“我们发现，云到云提供了网站工作中最大的灵活性和具有如此复杂几何形状的建筑物的注册。能够将您的数据一起注册，并与P40一起使用双轴补偿器，确保我们是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.

管理数据

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。

“使用Leica Jetstream的使用使我们能够在伦敦中心托管我们的数据，每个人都可以访问。如果我们的区域办公室进行扫描项目，他们可以在一夜之间上传到JetStream Server，向其他所有人开放数据。不是扫描数据但偶尔需要使用数据的团队，我们可以托管和存档他们的项目数据，”said Beach.

使用Leica Jetstream使团队能够在各个位置的各个团队之间传播最终数据集，以按时和预算完成项目。“ Jetstream使我们能够以最有效的方式和尽可能准确的方式完成该项目。”said Beach.

Delivering data

测量师使用激光扫描生成大量数据，这些扫描被捕获，处理和设法提供支持决策的可行数据。

Leica TruView is the collaborative tool Hollis surveying team relies on to share point cloud data and design models. One of the many uses for TruView within Tim’s team is as a Q&A tool to ‘walkthrough’ models and for checking congested environments remotely and safely.

“莉卡来回TruView提供了一个基于地理位置的视图数据m 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.

从数据收集到交付的完整端到端解决方案

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.
