Digital cities initiatives aim to collect valuable data and capture all surroundings in urban settings to generate smart models, supporting decision making processes and facilitating the delivery of new urban services. The mobile mapping, reality capture, airborne and asset management solutions provided by Hexagon Geosystems' Division are used in cities around the globe helping to digitise urban centres.

Aware that 3D models help to inform the perception on reality and provide a georeferenced digital base for operations in a city, Patronato Pikimachay, a non-profit organisation, approached C95 Creative, a leading global architecture and design firm, to create a smart digital city model of Ayacucho, Peru.


Ayacucho’s smart digital city project

C95 Creative specialists started the 3D digital modelling of this Peruvian city in 2017. To undertake a precise digital survey that would be the basis for a digital city model, the project collected georeferenced point clouds with images from 150 blocks in Ayacucho’s historic centre. Using a combination of Geosystems solutions, data from a50-kilometre trajectory was collected in three daysand the entire project deliverables were completed in six months.

“在决策未来的城市干预措施中,智能城市的宝贵数据库至关重要。我们已经能够为文化遗产,编目,恢复和翻新工程产生巨大价值的数据库。我们将继续探索并寻找使用Leica Geosystems将这项技术应用于我们的领域的新方法,”said Irene Ibisate, architect and director for the smart city Ayacucho project at C95 Creative.

Beyond the speed of obtaining and processing data, the quality and precision of the point cloud with overlaid images allowed C95 Creative to:

  • Create a 3D model of the entire city centre
  • 完成主要城市元素的目录
  • 对当前状况和保护状态进行研究
  • 进行文化遗产价值和保护研究
  • 产生三维地籍更新一个d geometric data base of the city with real dimensions
  • 生成城市的视频和图像,以作为未来干预工作的参考。

“要在BIM(建筑信息建模)中创建几个月来整个城市的再现是一个巨大的挑战。由于使用Leica Geosystems产品获得的精确性和速度,我们能够在短暂的一小段数据中使用完整的数据来捕捉现实亚搏彩票手机版下载多少时间,”说不平衡。

鉴于数据收集的时间有限,网站的大量扩展时间必须很快。亚博ag真人规律来自地理系统的现实捕获系统提高了专业人士以极其敏捷和有效的方式以毫米精度的限制区域中绘制,地理位置,捕获和提取功能的绘制,地理位置,捕获和提取功能的灵活性和流动性。

为了捕获Ayacucho的整个中心,C95 Creative用Leica Pegasus:两个开始了数据收集。使用此移动映射传感器平台,从三天内收集了50公里轨迹的数据。激光扫描是通过Leica ScanStation P40进行的,以提高行人区域和正方形的细节水平,并具有文化遗产资产。

“不可能使用传统的解决方案和工具进行此类项目。Leica Geosystems产品使我们能够远程合作,并以该网站的全面了解远程工作,”亚搏彩票手机版下载C95 Creative的BIM总监Maria Pascual说。

The data was processed and exported as imp.pts to Autodesk Revit, a BIM software. Leica Cyclone 3D point cloud post processing software, was used to post process the point clouds. To create a BIM model, the team worked with Leica CloudWorx and Leica JetStream software, allowing the better modelling and inclusion of the point cloud within the Autodesk Revit model.

“将点云建立为数据库是追求如此范围的项目的唯一途径。通过诸如Jetstream之类的强大产品使我们的BIM模型有助于加快和激发此过程。项目最终以质量增加了价值亚搏彩票手机版下载以及从这些最新工具中获得的精确度,这些工具可以创建以不同格式和平台可用的大型数据库,”帕斯卡尔说。


超越文化遗产价值

Urban planners, construction companies or government officials need to have a more dynamic perception of a city with georeferenced data that mirrors reality to produce any application or service and指导未来的干预措施。

3D模型允许记录,管理,续订或维护城市中的资产。要符合联合国教科文组织的标准,并将Ayacucho的历史中心宣布为世界遗产,需要进行恢复和维护工作。数字化城市模型将是创造对社会和经济发展至关重要的更可持续和有效的城市环境的基石。

C95 Creative提供的3D模型将是该地区内部任何建筑干预的基础,从而指导受保护的城市元素的文化遗产评估和重建,这可能会随着时间的流逝而降低。

Beyond the cultural heritage value, the deliverables have also been used for other purposes, such as:

  • Virtual reality (VR) and augmented reality (AR) of Ayacucho
  • Previsualisation of plans
  • Urban simulations
  • Touristic applications
  • Urban improvement analysis

Unleashing the full potential of reality capture

C95 Creative takes design to the smallest detail. One of the international leading firms in the AEC sector knows quality tools matter, so it has been using Leica Geosystems products for a long time.

“ C95发现了Leica Geosystems Reality Capt亚博ag真人规律ure Solutions,这是其BIM工作流程的理想工具。PEGASUS:两个允许在短时间内生成大区域的数据。P40用于扫描精度和速度,用于室内设计,康复,修复,翻新,工程和建筑。它与BLK360一起使用,以生成站点不同地标的数据并获得构建模型。此外,点云用于任何类型的数字调查,用于模拟的数据收集,报告,VR和AR,”帕斯卡尔说。

为了保持相关性,改善流程,不断提高质量并为其所有项目带来附加值,C95 Creative继续在其作品中引入最新的技术和流程。
