救援任务:使用现实捕获来计划前修道院的重建bob综合app赌博

案例分析

Author: André Azevedo

在葡萄牙布拉加(Braga)的Carmo Church旁边,坐在1653年成立的前Carmelite修道院。

To decide on the best way to sympathetically develop the complex site, which includes vaults, attics, and water features, Fortera asked civil engineering companyBuildgestto carry out a complete geometric survey. To capture the data needed to build a BIM model, André Azevedo, technical manager at Buildgest used a Leica Geosystems 3D laser scanning solution.


可视化3D中的环境

该修道院的内部和外部由多个建筑物,水平和室外空间组成。在任命BuildEmp之前,Fortera已经委托进行了2D调查。不幸的是,这没有足够的细节使他们自信地进入开发的设计阶段。Azevedo解释说:“经典的2D调查有一些缺陷,因此我们提出了激光扫描调查和建筑物的准确建筑模型。该建筑信息模型(BIM)将帮助客户的建筑师团队研究不同的干预场景。”


Faster scanning in the field with a streamlined reality capture solution



潜在的建筑区域为5,000平方米,复杂的几何形状和六周的截止日期,需要迅速进行现场工作。如果他们花了很长时间,他们的建模团队将没有足够的时间完成工作。

Azevedo已经是Leica Geosystems用户选择的Leica BLK360成像激光扫描仪,Cyclone REGISTER 360,Cyclone FIELD 360, 3DReshaper (旋风3dr) 和JetStream Viewer软件元素。

“我们需要可以快速准确地产生内部扫描的设备。与其他设备相比,扫描仪很小,轻巧,并促进了阁楼和洞穴等建筑物的困难区域的运输。产品和软件之间的工作流程流畅,快速。bob综合app下载例如,Cyclone Field 360自动预注册扫描。这使我们在田间更快地进行了扫描。” Azevedo解释说。


7天内600次扫描



Azevedo和他的团队并行使用了两个BLK360扫描仪,持续7天来扫描修道院的建筑物。BLK360-同类产品中最小,最轻的成像激光扫描仪 - 用全彩色全景图像覆盖在高精度点云上。为了确保整个点云是准确的,建立了一个调查控制网络,该网络在建筑物和内部周围具有激光扫描目标。

A total of 600 detailed scans were taken. To improve efficiency, Azevedo used the Cyclone FIELD 360 mobile-device app to pre-register the point cloud while still on site. In his words, “Pre-registration of the collected information in the field saved time in post-processing tasks.”


Easy synchronisation, interoperability and processing

回到办公室,建筑最大的团队使用旋风注册360来清洁和注册扫描,从而创建统一的点云。Azevedo说:“旋风场和旋风分离器寄存器之间的同步很好,可以易于使用。”

处理包括给出一些形状更多的定义。Azevedo解释说:“观赏细节,例如在内部露台上的中央喷泉是在3dreshaper的帮助下建模的。”然后,在五个星期的时间内,由两个建模者组成的团队进一步处理数据,为客户创建完整的体系结构BIM模型。Azevedo将准确扫描数据的价值解释为对此过程的价值,“对修道院的现有保管库进行建模是具有挑战性的,使用点云帮助我们完全了解了这些元素的几何形状。”


“It's helpful to review the model with the photographic record”



When the geometric survey was complete, Buildgest presented their findings to Fortera. As well as delivering the BIM model, and an LGS file of the data, Buildgest used a Cyclone Publisher Pro and JetStream Viewer to show the client how to explore and move the point cloud. They see this as the best way to communicate the results.

“We always recommend the JetStream Viewer to our clients, because it's more specific and helpful to review the model with the photographic record. Using the viewer, the client was able to see the 360 images that were captured in the scanning process. Besides, it gives them the option to navigate through the point cloud with a simple intuitive tool,” Explains Azevedo. JetStream Viewer Portable is a free, no-install version designed for easy visualisation, to let those without survey training experience point cloud data.

Buildgest能够快速完成该项目,而不会损害质量。Fortera的首席工程师Pedro Ferreira说:“ Fortera对交付的信息的数量和质量感到非常满意。”现在,开发人员的建筑师计划对建筑物进行重新发明,并在修道院的350年故事中增加了另一章。
