Unveiling the past with reality capture

古罗马城市塔拉科（Tarraco）是当今西班牙加泰罗尼亚地区的塔拉贡（Tarragona），是伊比利亚半岛上最古老的罗马定居点，曾经是半岛领土的首都。塔拉戈纳（Tarragona）光荣过去的建筑遗迹包括其他废墟，马戏团，剧院和圆形剧场。这个考古合奏是2000年前建造的，自2000年以来是联合国教科文组织世界遗产的一部分。

The Catalan Institute of Classical Archaeology (ICAC) and the Architecture School of the URV (ETSA) joined efforts with the help of ARREL Project of the RecerCaixa program to study, preserve and transmit the cultural richness of Catalonia’s past using Leica Geosystems’ state-of-the-art laser scanning technologies and a unique mobile mapping solution - the飞马：背包。

忠实的考古学家团队熟练地将点云和HDR数字图像转变为3D CAD模型。这些技能，加上它们的深入历史和考古知识，有助于揭露并了解这个罗马城市的秘密这曾经是罗马帝国其他地区的省首都的榜样。

看大局

详细的数字3D模型是对现实的重建，可以研究确定的空间。

罗马马戏团的三维数字模型是从点云获得的大型战车比赛和赛马的大型露天娱乐场所study and understand the initial state and transformationthat this heritage site has experimented during two millennia.

“The laser scanning solutions from Leica Geosystems allow us to数字化可视化并理解复杂的现实of this four hectare enclosure occupied by the Roman Circus, located today in Tarragona’s old town, that represented a real challenge of Roman engineering and that is intensely altered from the actions developed since the fifth century,”ICAC高级研究员Josep M.MaciasSolé说。

The 3D models generated with the point clouds helped the team of specialists to achieve:

• 以数字方式重建罗马马戏团，甚至找到逃脱人眼的部分。
• Interpret the components of the structure to test hypothesis about the circus’ capacity and the logic behind its initial construction and later buildings.
• 在几个世纪以来，破译了当地景观的发展，以确定这种罗马教育如何在中世纪和现代的城市城市地块中局限于城市地块。

Putting the pieces together with mobile reality capture

The structure that initially served as a Roman circus, suffered profound architectural changes through the years and now it is inserted and hidden under the urban landscape of Tarragona. The Roman circus, located in the city centre, has exhibition areas opened to visitors, however, the old vaults that support the stage serve today as structures to hosts bars, restaurants and even private residences.

使用一代Leica Geosystems的激光扫描仪，与C5和C10一起使用一代左侧的激光扫描仪，已经进行了几项努力，以使用最新的激光扫描技术之一 - Leica P30。iCAC和ETSA已通过现实捕获传感器平台最终使这些努力达到顶峰bob综合app赌博统一所有以前的扫描 -飞马：背包。

All the visible parts of the Roman circus have been documented with the laser scanners. The Pegasus:Backpack, however, made it possible tocapture every step of all the streets and facades塔里亚纳（Tarragona）的旧城区，该城镇插入了罗马马戏团所占据的地区。这种独特的现实捕获解决方案的使用还促进了城市的bob综合app赌博当代和古老建筑的图形整合到一个单一的工作流程中。

“The Pegasus:Backpack offers us the great advantage of being able to cover areas that otherwise would be very cumbersome and very expensive with more traditional survey systems. With this tool we could消除大部分现场工作然后处理数据并将其与我们为整个区域的全面文档进行的其他项目拟合，”MaciasSolé说。

“All this process ofcapturing data with millimetric precision一直非常敏捷有效, and we always指望技术支持以及Leica Geosystems专家的持续建议。”

连接学科

The archaeological remains of the Roman circus are a testimony of Roman architecture and planning and provide the blueprints on how this ancient construction developed and transformed Tarragona’s history and landscape with every century.

3 d文档在塔拉的遗产gona allowed archaeologists at ICAC and architecture students at ETSA to develop:

• 历史城市研究
• 历史遗产的教育学和博物馆
• 考古研究
• Cadastral plans and a heritage management system

通过激光扫描捕捉现实，打开了一扇门，来自考古学家和建筑师等几个学科的专家可以汇聚以研究，映射，监视和节省任何建筑物或资产。As seen in Tarragona, Spain, Leica Geosystems’ solutions help professionals become more efficient and accurate on how they produce, share and evaluate information.
