bob综合app赌博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

作者：Duncan M B Lees

A ground-breaking new TV series for National Geographic combines hi-tech science, breath-taking visuals and genuine exploration to bring to life some of the most extraordinary sites of antiquity.失落的城市with Albert Lin从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 scanningsolutions.

Laser scanning: an exciting new tool for archaeology and exploration

激光扫描技术对于捕获和重塑3D细节的水平至关重要，否则无法实现，以了解现实对我们祖先的表现。在以色列的Akko（英亩）中谈到废墟时，Lees解释说：“使用无人机，陆地和空中激光扫描仪以及我们的定制AR软件，我们使Albert能够退后一步，并真正可视化了这座城市，就像在Crusader中一样时代。”

Visualskies将扫描设备的自定义组合组合在一起，包括Leica ScanStation P50long range 3D terrestrial laser scanner, the highly portableLeica RTC3603D激光扫描仪和狮子旋风和3dreshaper（Cyclone 3DR) point cloud processing software.

Meeting challenging weather conditions and inaccessible terrain

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.”

“A startling impact:” Using 3DReshaper to ‘see’ through dense vegetation

One of these difficulties was dense vegetation. Lees explains: “The majority of the Tayrona complex (in Ciudad Perdida) is almost invisible due to the lush tree cover over the whole Sierra Nevada mountain range, so it was going to be almost impossible to document, digitise and visualise the lost remains using solely traditional survey techniques.”

The team used a combination of aerial and terrestrial scanning techniques and 3DReshaper (Cyclone 3DR) in post-processing to achieve their goal. “It is a perfect solution for cleaning, segmenting and filtering point clouds for a number of 3D modelling and inspection deliverables. 3DReshaper provides us with the ability to strip away the tree cover and visualise what lies below; something that has had a startling impact on many of the projects we have undertaken.”

减轻紧迫的时间尺度的压力和“一次机会”获得结果

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series was incredibly compact; with digitally documenting the numerous sites, visualising the remains and filming the whole programme all being undertaken in one relatively short concurrent timescale,” explains Lees.

使用的设备需要快速设置和易于使用，从而减少了团队承受的压力和压力。扫描仪P50和RTC360都是快速扫描仪。使用ScanStation P50，团队能够在Jordan的Khirbet Al -Darieh捕获整个网站 - 并在一天之内就可以准备好进行播放的3D模型。

Lees说：“ RTC360一直是我们3D现实捕获功能的游戏增加。bob综合app赌博现在，我们可以在任何工作班次中收集超过两倍的数据，或者更重要的是，将我们在任何位置捕获数据的时间减半。”处理软件的速度同样重要。Lees继续说：“旋风可以处理大量的陆地激光扫描数据 - 数百个单独的扫描仪设置，导致数亿个单独的点 - 能够轻松地对地理空间点云数据集进行注册，操纵和分析。”

“The use of laser scanning and 3D modelling on失落的城市with Albert Lin不仅对观众着迷，而且还具有真正的考古价值。” Lees说。例如，在Pohnpaip的太平洋岛上，Visualskies船员扫描了一个非凡的收藏，其中700多个史前图案雕刻成自然的玄武岩露台。“通过创建岩画的3D模型，我们使阿尔伯特和船员澄清了褪色的岩画的确切形式，详细研究它们并与太平洋其他地方的其他古老雕刻进行了比较。”

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VSScouthas been designed as a tool-kit to aid productions to explore locations in a radically immersive manner, whilst simultaneously collecting rich geomatic data that can be utilised across departments enabling all crew to access the site remotely.

Lees concludes, “It is our privilege and pleasure to work with exceptional professionals in incredible places around the world, dovetailing our bespoke solutions into the creative process to produce breath-taking results for all to see.”
