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。

Making it official

为了获得世界纪录，Jafri先生需要验证记录尝试的真实性和实际的画布大小。吉尼斯世界纪录是一个整理和发布许多壮举记录的组织，他们的唱片裁决者回答了电话，以确保精确创建绘画，并且足够大以创造世界纪录。

The adjudicators understood that the size of the canvas would need to be verified with absolute accuracy and approached Dubai-basedPRD Survey Services协助测量。自2010年以来，PRD已成为该地区在水平和垂直混合用途社区和复杂地层标题分区的领先调查咨询公司之一。他们为整个中东地区的开发商提供了一套调查咨询，现场调查，计划准备和标题的注册服务。为了完成许多任务，他们正在使用Leica RTC360 3D激光扫描仪.

正确的设备

PRD同意进行磨破的测量ld record attempt free-of-charge and assigned their Survey and Special Projects Manager, Chris McGinty, a Chartered Land Surveyor from the United Kingdom, to carry out the measurement. In 2019, Chris was responsible for driving PRD’s adoption of Reality Capture technology when they invested in their RTC360. As an existing customer of Leica Geosystems, he did not hesitate to approach the local Leica Geosystems technical support team in Dubai for support with the world record project; this is a team that he is familiar with, as they were there to assist PRD at every stage of their adoption of Reality Capture technology.

共同决定采用两种产品来测量画布以提供冗余：亚搏彩票手机版下载Leica Nova MS60 MultiStation, and PRD’s RTC360. Both instruments provided the accuracy required for the record attempt, but the RTC360 was selected on the day to measure the record due to the high density of points it was able to measure in a short space of time. Due to the canvas sides being unreliable and showing deviations, an accuracy of around +/10mm was predicted.

According to McGinty,

“It was a high-pressure environment that was being filmed, so the measurements had to be correct. We needed to make sure that PRD did not make a mistake and make sure we selected the right equipment that could be relied upon.”

Once the 3D representation of the canvas was captured with the RTC360, the data was quickly downloaded, processed and inspected usingLeica Cyclone Field 360software. This allowed the team to provide the 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.

It was decided by PRD that two of their 18 surveyors would be trained to use the RTC360 3D laser scanner. This training took the form of a dedicated two-day training course, delivered by the local technical support team based in Dubai. McGinty believes that despite his team being new to Reality Capture technology, they found the RTC360 very easy to use from the beginning, although he is thankful they received ongoing support from the local technical team during this period.

该团队主要使用其RTC360 3D激光扫描仪检查现有建筑物的计划。然后将该信息用于提交给迪拜土地部和其他当局的信息，以解决有关商业场所和商业场所领域的问题。PRD相信以3D点云的形式捕获这些前提的完整地板，可确保测量的绝对准确性。这意味着所有有关方面都对他们提交的信息是正确的信息更加有信心。RTC360的速度也对PRD也有益，因为对商业站点的访问有限意味着它们在捕获数据时必须非常快。他们还认为，捕获所有数据，然后能够使用Leica Cyclone REGISTER 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对RTC360非常满意，尤其是在初始培训期间及以后的当地团队获得的支持速度和援助的速度。McGinty认为，Leica Geosystems提供的硬件和软件解决方案确实可以帮助PRD多样化和发展业务，同时使客户受益。

“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手持式成像激光扫描仪, 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。”
