亚博ag真人规律现实捕获在国家地理失落的城市与阿尔伯特·林（Albert Lin）中扮演着重要角色

Author: Duncan M B Lees

一部针对国家地理的开创性的新电视连续剧结合了高科技科学，令人叹为观止的视觉效果和真正的探索，以使一些最非凡的古代景点栩栩如生。失落的城市与艾伯特·林（Albert Lin）from Blakeway Productions follows the explorer Dr. Albert Yu-Min Lin as he uncovers new insights about forgotten cities and cultures.

High-definition 3D mapping specialistsVisualskies被引入以在位置提供定制的3D扫描服务，并为节目创建空间数据可视化。Visualskies 3D扫描专家Duncan M B Lees解释说：“我们与Albert和Blakeway Crew紧密合作，基于科学方法来开发一种叙事，以收集空间数据。结果是一系列雄心勃勃的节目，通过我们的高科技图像提供强大的情感故事。”

To bring the mysteries of the past vividly into focus in the present, Visualskies usedLeica Geosystemslaser scanning解决方案。

激光扫描：考古和探索的令人兴奋的新工具

Laser scanning technology was crucial to capture and remodel a level of 3D detail otherwise impossible to achieve, to build a picture of how reality would have looked to our ancestors. Speaking about ruins in Akko (Acre) in Israel, Lees explains, “Utilising drones, terrestrial and aerial laser scanners and our custom-built AR software we enabled Albert to step back in time and truly visualise the city as it used to be in Crusader times.”

Visualskiesput together a custom combination of scanning equipment, including theLeica ScanStation P50long range 3D terrestrial laser scanner, the highly portableLeica RTC3603D激光扫描仪和狮子旋风和3dreshaper（旋风3dr）点云处理软件。

满足具有挑战性的天气状况和难以接近的地形

被选为该计划中的所有站点都为电影和调查人员带来了挑战。李斯说，从约旦的50度沙漠到马丘比丘的高海拔，“在稀有气氛中加工在帐篷中，只有一对气质发电机的权力不理想，”李斯说。所用的设备既可以便携式又耐用。扫描仪P50的远程功能意味着机组人员可以覆盖大区域，并从安全地点扫描无法接近的地点，同时仍然捕获高水平的细节。激光扫描仪可以快速设置，可以在极端温度范围内执行，并且足够难以承受丛林跋涉。

Accessing Ciudad Perdida (literally 'Lost City') in Santa Marta, Colombia, required a lengthy journey involving first planes and helicopters, then hiking, with the team carrying everything they needed themselves. Lees explains, “Our first impression of the extant remains of the Lost City was a spectacular aerial view that underlined just how difficult it was going to be to document the city and the vast landscape around Ciudad Perdida.”

“令人震惊的影响：”使用3dreshaper通过茂密的植被'看到'

这些困难之一是茂密的植被。Lees解释说：“由于整个内华达州内华达山脉的郁郁葱葱的树木覆盖物，大多数泰Rrona综合体（在Ciudad Perdida中）几乎看不见完全是传统的调查技术。”

该团队在后处理中结合了空中和陆地扫描技术和3Dreshaper（Cyclone 3DR），以实现其目标。“这是用于清洁，细分和过滤点云的完美解决方案，用于许多3D建模和检查可交付成果。3Dreshaper使我们能够剥离树盖并可视化下面的内容；这对我们进行的许多项目产生了令人震惊的影响。”

Easing the pressure of tight timescales and ‘one chance’ to get results

Along with geographical constraints, Visualskies needed to survey quickly, to meet a tight travel schedule and tight film production deadlines. “The schedule for the whole失落的城市系列非常紧凑；通过数字记录众多站点，可视化遗体并拍摄整个程序，所有程序都在一个相对较短的并发时间范围内进行。” Lees解释说。

The equipment used needed to be quick to set-up and easy-to-use, reducing the stress and pressure that the team were under. Both the Scanstation P50 and RTC360 are fast scanners. Using the ScanStation P50 the team were able to capture an entire site at Khirbet al-Darieh, Jordan - and have a 3D model ready to film for broadcast - in just one day.

Lees says that “the RTC360 has been a game changing addition to our 3D reality capture capabilities. We can now collect over twice as much data in any working shift or, more importantly, halve our time capturing data at any location.” The speed of processing software is equally as important. Lees continues, “Cyclone can process huge amounts of terrestrial laser scanning data - hundreds of individual scanner setups resulting in many hundreds of millions of individual points - enabling the registration, manipulation and analysis of the resulting geospatial point cloud dataset with ease.”

“在使用激光扫描和3D建模失落的城市与艾伯特·林（Albert Lin）was not only fascinating for audiences, but it has also real archaeological value too,” says Lees. For example, on the Pacific island of Pohnpaip, the Visualskies crew scanned an extraordinary collection of over 700 prehistoric motifs carved into a natural basalt terrace. “By creating 3D models of the petroglyphs, we enabled Albert and the crew to clarify the exact form of the fading petroglyphs, to study them in detail and to make comparisons with other ancient carvings from elsewhere in the Pacific.”

该计划的工作为Visualskies创造了一个新的方向，使他们为电视和电影业开发了开创性的侦察工具。应于2021年1月官方发布VSSCOUT已被设计为一种工具套件，以帮助制作以根本沉浸式的方式探索位置，同时收集可以在各个部门使用的丰富地理数据，使所有工作人员都可以远程访问该站点。

Lees得出结论：“与世界各地令人难以置信的地方与杰出的专业人士合作，将我们的定制解决方案融入创造性过程，为所有人提供令人叹为观止的结果，这是我们的特权和荣幸。”
