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.

His ‘Humanity Inspired’ project set out with two 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

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.

The adjudicators understood that the size of the canvas would need to be verified with absolute accuracy and approached Dubai-basedPRD 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 Laser Scanner。

The right equipment

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.

A joint decision was made to take two products to measure the canvas in order to provide redundancy: aLeica 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.

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.”

一旦用RTC360捕获了画布的3D表示，则可以快速下载，处理和检查数据Leica 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

麦金蒂（McGinty）使用Leica Geosystems产品已有35年以上，亚搏彩票手机版下载并使用了著名的野生T2 Theodolite和野生T2002电子理想来的遗产仪器。他指出，PRD选择投资RTC360，这主要是由于地方关系和迪拜提供的支持。

“总会有人您可以拿起电话并与之交谈。这种支持水平一直影响着我们选择Leica Geosystems。我还发现提供的解决方案是高度精致的 - 从可用性，兼容性，配件甚至包装中。一切都起作用了，”麦金蒂说。

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。然后将信息用于提交给迪拜土地部和其他当局的书名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都更加有信心。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.

据McGinty称，这更重要

“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 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.

“ Leica RTC360使我们能够为客户提供更多服务，并更快地完成工作。对现场的访问次数减少；这一切都可以帮助我们提高效率，并为客户提供这些成本效益。” McGinty解释说。

PRD现在正在调查Leica BLK2GO handheld imaging laser scanner，这会在您移动时重新创建3D空间。它是手持式，无线和轻量级的，设计用于用户使用的任何地方，旨在在移动中快速捕获现实。他们认为，这可能是他们开发的下一步，使他们能够为受信任的客户提供更多的服务和更高的效率。

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.”
