RESI-通过陆地激光扫描从2D过渡到3D

Author: Simon Hall

resi是一项多合一的建筑服务，提供测量，设计，规划支持，建筑法规包，财务和对审查的承包商和专家的介绍。

resimay have started small, but they’ve quickly risen to become the UK’s leading architectural service. Since 2016, they’ve helped over 4000 homeowners nationwide, and they’re only getting bigger! Founded by two of the UK’s foremost female tech entrepreneurs - Jules Coleman & Alexandra Depledge - Resi boasts over 120 employees, with in-house architects, surveyors, technicians, and even mortgage brokers.

亚历克斯（Alex）和朱尔斯（Jules）将RESI设想为一个多合一的平台，可以帮助现代化经常乏味的改善或建造房屋的过程，这两者都受到其噩梦项目的启发。他们与两位经验丰富的建筑师 - 尼克·斯托克利（Nick Stockley）和里奇·摩根（Rich Morgan）合作，他们带来了十年的行业经验。通过将这个建筑知识与创新技术解决方案相结合，Resi进入了世界，准备在住宅领域大放异彩。

“We have a large variety of projects at Resi. From small flats in Central London, to large country houses with a lot of land. Generally, we work with tight timeframes. All of our projects are residential.”Lisa Westmacott - Head of Pre-Design, Resi

从2D过渡到3D

resibegan working in 2D, creating floor plans and sections from hand-drawn measured building surveys to inform the design process. As the company expanded, the demand for measured surveys increased, and Resi took the opportunity to investigate ways in which they could develop and enhance their surveying capabilities.

As a business, Resi embraced innovation and saw an opportunity to transition into a 3D workflow for design and surveying; this is where the partnership with Leica Geosystems was forged.

“我们正在为人们创造一种新的方式来改变自己的房屋，并始终想挑战自己，为客户提供最佳服务。我们从不害怕在盒子外面思考或进行实验！”Heather Shaw - ‎Communications Manager, Resi

Choosing the right equipment

Since 2017, Resi has worked on over 4,000 separate projects, and with so many customers, they needed to find a way to speed up data capture for their measured surveys. While the pursuit for greater productivity is instigated by increased demand, Resi was also keen to enhance deliverables and realise the highest levels of accuracy in their work, thereby mitigating risk throughout the project journey.

Through research and introductions to new processes, Resi approached Leica Geosystems to aid them in their transition from traditional measurement techniques to digital data capture and 3D laser scanning. Resi has since invested in a fleet ofLeica RTC360 3D laser scanners，结合强大的Leica Cyclone REGISTER 360post-processing office software, providing the perfect solution for their project work.

优化工作流程

Leica Geosystems aided Resi in implementing their new products, providing training, technical support and consultation to help Resi optimise their workflows.

The RTC360 3D reality capture solution allowed Resi to document and capture their projects in 3D, with precision laser measurements forming a point cloud – essentially capturing the reality of any site and subject matter in high definition with unparalleled speed.

The Leica RTC360 3D Laser Scanner automatically preregisters point cloud data in the field to quickly conduct quality control checks, improve productivity and allow Resi to make better-informed decisions on site.

As well as measuring up to 2 million points per second with its lasers, the RTC360 laser scanner captures enriching High-Dynamic Range (HDR) imagery as a panoramic view in one minute, augmenting the point cloud to provide real-world visualisations from which measurements are taken.

Each scan position merges seamlessly to the next by way of the RTC360’s unique视觉惯性系统（VIS），它使用功能跟踪技术与集成的惯性测量单元配对，可实时提供标题和相对定位。五个VIS摄像机跟踪运动和每个扫描相对于彼此的扫描，因此直接在田野中建立了一个真实的生命3D可视化；全部由Leica Cyclone FIELD 360mobile-device app running on a smartphone or tablet computer (iOS or Android).

By working with the Cyclone FIELD 360 app to build links while the teams scan, Resi save time processing the data in the office as the scans are already positioned relatively. GeoTags are added to the captured scans to help illustrate key features and mark up areas for collaborative working, providing greater understanding of each projects unique challenges.

“No other solution we looked at seemed to marry so well with speed and accuracy. It was incredibly useful to have a 3D ‘digital twin’ of the property to reduce the need to ever re-survey when collecting measurements by hand. Our customers also really like seeing their property in 3D. Using the Leica solutions means we can carry out more surveys in one day, and they are much more accurate than hand-collected measurements.”Lisa Westmacott - Head of Pre-Design, Resi

resiis now exploring dynamic data capture with theLeica BLK2GO handheld imaging laser scanner。小于1公斤和映射在超过400,000 points per second, the BLK2GO mobile solution provides Resi with the ability to create accurate 3D representations of their projects while they walk through the property. By combining LiDAR SLAM (Simultaneous Localization and Mapping) technology and the feature tracking VIS, Leica Geosystems has created a GrandSLAM solution that facilitates centimetre precision at a range of up to 25 metres. Data capture in awkward spaces, over and under objects, through rooms and doorways, around corners, and up and down stairwells is easily measured at walking pace.

A view to the future

随着RTC360的实施，RESI能够快速有效地仔细检查其调查信息，而无需重新访问项目站点，从而提高了效率并降低了具有灵活工作机会的工作地点的旅行成本。Leica Geosystems继续支持RESI，以帮助制定3D激光扫描的业务战略。该公司具有快速增长的战略，并计划在市场领先技术中进行投资。

“Leica Geosystems helps us do in hours what would have taken days. It means our surveying team can be more productive and keep up with customer demand. We plan on continuously expanding the company and continue to use 3D laser scanners. We have enjoyed using Leica Geosystems products. The software has helped create a seamless workflow. We are looking forward to seeing more improvements and new technology in the future.”Lisa Westmacott - Head of Pre-Design, Resi

RESI首席执行官Alex Depledge的首席执行官办公室对RTC360解决方案印象深刻，以至于她在自己的家中开始了一个项目以扫描并捕获3D的空间，以使他们的团队为她设计完美的空间。
