验证记录的绝对准确性以帮助世界

作者：理查德·戴维斯

是2020年3月，英国艺术家Sacha Jafriis one of many to be impacted by the COVID-19 pandemic when he found himself stuck in Dubai, United Arab Emirates, during a lockdown. Famous around the world for his large-format paintings, Mr Jafri has been dedicated to helping people, especially the young, throughout his career. Over the past 18 years, sales of his paintings have helped to raise USD $60m for children’s charities around the world, and so he decided that he would use his time in lockdown to make a positive impact on a variety of people and organisations.

他的“人类灵感”项目设置了两个clear goals: raise $30 million USD for various charities whilst setting a new world record for the ‘Largest Painted Art Canvas in the World’. Children from across the globe were invited to share their own artworks online, with a theme of ‘connection and isolation’; Mr Jafri then used these submissions as a base for the 17,000-square-foot artwork he planned to create. The response was phenomenal; children from 140 countries sent in their work, with over 6,000 submissions the first 24 hours alone. Mr Jafri needed a workspace large enough to lay out and paint the huge canvas, and the ballroom of the famous Atlantis, The Palm hotel in Dubai was chosen as a suitable venue.

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调查服务协助测量。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 Laser Scanner。

正确的设备

PRD agreed to carry out the measurement of the world 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：bob综合app下载Leica Nova MS60多阶段, 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.

根据麦金蒂的说法

“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.

本地支持

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 360software when back in the office prevents returns to the site, which can be costly and time-consuming.

根据麦金蒂的说法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.”

Benefitting business in the long term

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现在正在调查Leica 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.

As for Mr Jafri, he is now officially in the record book and the sale of his painting has begun, with 70 individually numbered, signed, catalogued, and framed panels being individually auctioned over the coming 12 months. The proceeds will help some of the poorest communities in the world, with a goal of saving 10 million child-lives. He also hopes to “bring education, healthcare and opportunities to those that have previously had neither, with the goal of giving those that need it most a very real opportunity to change the world around them.”
