数字城市倡议旨在收集有价值的数据并在城市环境中捕获所有周围环境，以生成智能模型，支持决策过程并促进新的城市服务的交付。由Hexagon GeoSystems的bob综合app赌博部门提供的移动映射，现实捕获，机载和资产管理解决方案用于全球各个城市，有助于数字化城市中心。bob体育报道

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.

“A valuable data base for smart cities is essential during the decision making of future urban interventions. We have been able to generate data bases of great value for cultural heritage, cataloguing, restoration and refurbishment works. We will keep exploring and looking for new ways of applying this technology in our sector with Leica Geosystems,"C95 Creative的Smart City Ayacucho项目的建筑师兼总监Irene Ibisate说。

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
• Complete a catalogue of the main city elements
• Develop a study of the current situation and conservation state
• 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。

"To create in BIM [Building Information Modelling] a reproduction of an entire city in a few months was a great challenge. Thanks to the precision and speed obtained with Leica Geosystems products, we have been able to capture reality with complete data in a short amount of time,"说不平衡。

Digitalising environments

Given the limited time for data collection and great extension of the site, scanning had to be fast. Reality capture systems from Geosystems increase the flexibility and mobility of professionals to map, geo-position, capture and extract features over LiDAR or photogrammetry measurements in restricted areas with millimetric precision in an extremely agile and effective way.

为了捕获Ayacucho的整个中心，C95 Creative用Leica Pegasus开始了数据收集：两个。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。LASER扫描是通过Leica Scanstation P40进行的，以通过文化遗产资产提高行人区域和正方形的细节水平。

“使用传统的解决方案和工具进行此类项目是不可能的。Leica Geosystems产品使我们能够远程合作，以远程了解该网站，”bob综合app下载C95 Creative的BIM总监Maria Pascual说。

该数据被处理并导出为Imp.pts，以供BIM软件Autodesk Revit。Leica Cyclone 3D Point Cloud Post Procesing软件用于发布点云。为了创建BIM模型，该团队与Leica CloudWorx和Leica Jetstream软件合作，从而使点云更好地建模和包含在Autodesk Revit模型中。

“要建立点云作为数据库是追求如此范围的项目的唯一方法。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这一过程。由于质量，项目最终以附加值为准。bob综合app下载以及从这些最新工具中获得的精度，这些工具可以创建以不同格式和平台可用的大型数据库，”pascual说。

Beyond cultural heritage value

城市规划师，建筑公司或政府官员需要对城市具有更具动态的认识，并具有地理参与数据，以反映现实以产生任何应用或服务，guide any future interventions.

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更可持续和有效的城市环境对社会和经济发展至关重要的基石。

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

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

• Ayacucho的虚拟现实（VR）和增强现实（AR）
• 计划的预言
• 城市模拟
• 旅游申请
• Urban improvement analysis

释放现实捕获的全部潜力bob综合app赌博

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 Captbob综合app赌博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，报告，VR和AR的数据收集，”pascual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。
