Verifying absolute accuracy for records to help the world

Author: Richard Davies

It is March 2020, and British artistSacha Jafri当他发现自己在锁定期间被困在阿拉伯联合酋长国的迪拜时，他是众所周知的大流行中的众多人之一。贾弗里（Jafri）先生以他的大幅面画而闻名，他一直致力于帮助人们，尤其是年轻人的职业生涯。在过去的18年中，他的绘画的销售有助于为世界各地的儿童慈善机构筹集了6000万美元，因此他决定利用自己的时间在锁定上对各种各样的人和组织产生积极影响。

他的“人类启发”项目制定了两个明确的目标：为各种慈善机构筹集了3000万美元，同时为“世界上最大的彩绘艺术画布”树立了新的世界纪录。来自全球的孩子被邀请在线分享自己的艺术品，主题是“联系和隔离”。然后，Jafri先生将这些意见作为他计划创作的17,000平方英尺的艺术品的基础。反应是惊人的。来自140个国家 /地区的儿童派遣工作，仅在前24小时内就有超过6,000份提交的意见。Jafri先生需要一个足够大的工作空间来布置和涂上巨大的画布，而著名的亚特兰蒂斯（Atlantis）的宴会厅被选为合适的场所。

使其正式

To achieve the world record, Mr Jafri needed to verify the authenticity of the record attempt and the actual canvas size. Guinness World Records are an organisation that collate and publish notable records of many feats, and their record adjudicators answered the call to make sure the painting was created precisely and was large enough to set a world record.

裁决者理解，需要绝对准确的画布的大小，并接近基于迪拜的PRD Survey Servicesto assist in the measurement. Since 2010, PRD has become one of the region’s leading survey consultancies in horizontal and vertical mixed-use communities and complex strata titling subdivisions. They provide a full suite of survey consultancy, on-site surveying, plan preparation and titles registration services to developers throughout the Middle East region. To complete many of their tasks, they are using aLeica RTC360 3D激光扫描仪.

The right equipment

PRD同意进行世界纪录的衡量，并分配了他们的调查和特殊项目经理Chris McGinty（来自英国的特许土地测量师），以进行测量。2019年，克里斯（Chris）投资RTC360时，负责推动PRD采用现实捕获技术。亚博ag真人规律作为Leica Geosystems的现有客户，他毫不犹豫地与迪拜的当地Leica Geosystems技术支持团队联系，以支持世界纪录项目。这是一个他熟悉的团队，因为他们在那里采用现实捕获技术的每个阶段都在那里协助PRD。亚博ag真人规律

A joint decision was made to take two products to measure the canvas in order to provide redundancy: aLeica Nova MS60 MultiStation和PRD的RTC360。两种仪器都提供了记录尝试所需的准确性，但是当天选择了RTC360，以测量由于能够在短时间内测量的高度点而导致的记录。由于帆布侧不可靠并显示偏差，因此预计 +/10mm的精度为大约 +/10mm。

According to McGinty,

“这是正在拍摄的高压环境，因此测量必须是正确的。我们需要确保PRD不会犯错，并确保我们选择了可以依靠的正确设备。”

Once the 3D representation of the canvas was captured with the RTC360, the data was quickly downloaded, processed and inspected usingLeica Cyclone Field 360软件这允许团队提供的Guinness World Records adjudicators with accurate measurements of the canvas extremely quickly. McGinty was able to confirm that the canvas did indeed set a new world record – the organisers were amazed by the technology used and delighted with the speed and accuracy of the results.

Local support

McGinty has been using Leica Geosystems products for over 35 years, and worked with legacy instruments such as the acclaimed Wild T2 Theodolite and the Wild T2002 electronic theodolite. He states that PRD chose to invest in the RTC360, primarily due to local relationships and the support provided in Dubai.

“There is always somebody you can pick up the phone and speak to. This level of support is something that has always influenced our choosing of Leica Geosystems. I also find that the solutions offered are highly refined - from usability, compatibility, accessories and even the packaging. Everything just works,” says McGinty.

PRD决定，他们的18位测量师中有两名将接受RTC360 3D激光扫描仪的培训。这项培训采用了由迪拜当地技术支持团队提供的专门为期两天的培训课程的形式。麦金蒂（McGinty）认为，尽管他的团队是现实捕获技术的新手，但他们发现RTC360从一开始就非常易于亚博ag真人规律使用，尽管他很感谢他们在此期间得到了当地技术团队的持续支持。

The team are mainly using their RTC360 3D laser scanner for checking plans of existing buildings. The information is then utilised in submissions to the Dubai Land Department and other authorities for issues surrounding titling and areas of commercial premises. PRD believe capturing the full floorplate of these premises in the form of a 3D point cloud ensures absolute accuracy of measurements. This means all parties involved are far more confident that the information they submit is correct. The speed of the RTC360 is also beneficial to PRD, as limited access to commercial sites means they have to be very quick when capturing data. They also believe that capturing all of the data and then being able to visualise sites usingLeica Cyclone寄存器360在办公室回到办公室时，软件可防止返回该网站，这可能是昂贵且耗时的。

According to McGinty, this is even more important due to COVID-19 restrictions,

“Our staff need to be tested for COVID-19 in order to travel to Abu Dhabi from Dubai, where we are based. After the fourth day of travelling into Abu Dhabi, they need to be re-tested. This is time-consuming and costly. The RTC360 allows us to capture all the data we need within the 4-day window, even on a large site. We can then inspect the data using Leica Cyclone software when back in the office and take what we need. Nothing is missed.”

从长远来看使业务受益

PRD are very satisfied with RTC360 and especially with the speed of support and assistance received from the local team, both during the initial training and beyond. McGinty believes that the hardware and software solutions provided by Leica Geosystems can really help PRD diversify and grow their business whilst benefitting their customers.

“The Leica RTC360 has allowed us to offer more services to our customers and complete jobs faster. The number of visits to site are reduced; this all helps us to be more efficient and to offer of these cost-effective to customers,” explains McGinty.

PRD are now investigating theLeica BLK2GO handheld imaging laser scanner, that recreates spaces in 3D as you move. It is handheld, wireless, and lightweight, designed for fast capture reality on the move, anywhere the user goes. They believe that this may be the next step in their development, allowing them to offer more services and higher efficiency to their trusted customers.

至于Jafri先生，他现在正式出现在唱片中，他的绘画的出售已经开始，有70个单独编号，签名，分类和框架面板在未来12个月内被单独拍卖。收益将帮助世界上一些最贫穷的社区，目的是节省1000万个孩子。他还希望“将教育，医疗保健和机会带给以前既没有的人，旨在为那些需要它的人提供最真实的机会来改变他们周围的世界。”
