案例分析

RM Surveys, an Australian firm providing end-to-end survey solutions for commercial, resource and residential industries, is excited to be part of the new西澳大利亚博物馆建筑项目。395.9澳元的项目包括设计和建造与现有遗产建筑集成的新建筑物;遗产修复工作可为老监狱,禧年,博福特和哈克特建筑物起作用;以及新西澳大利亚博物馆网站的公共艺术项目。

The dramatic new design links contemporary architecture with historic and heritage-listed buildings. The architects' main task was to merge the historic and heritage-listed buildings with the new state-of-the-art structures.

任务?四,最初由木材制成的遗产建筑需要结构钢,以增强和启用改进的展览。RM调查的任务是该项目的激光扫描组件,其中包括大型大厅,其中包括6,000平方米的画廊,参加大型特别展览,学习工作室,空间,以体验西澳大利亚博物馆的幕后工作。


去其他没有其他激光扫描仪的地方



The RM Surveys team used a couple of Leica Geosystems solutions to capture, model and analyse the data. Starting with theLeica Scanstation P40survey-grade 3D laser scanner, the surveyors used the ScanStation P40 for the large halls due to its high accuracy in large spaces.

西澳大利亚博物馆项目是第一个整合新的机会Leica BLK360将激光扫描仪成像到项目工作流程中。

The team captured the roof space and the timber beams for a fabricated steel substructure which would be prefabricated and installed to support the 100-year-old timber beams and roof structure.

For this portion of the project, the BLK360 was the only laser scanner for the job as no other product could match the portability and access the confined hazardous work environment. The team also needed to navigate using the equipment while wearing special PPE and fall arrest devices.

“这个项目使我们能够在小空间中了解BLK360的功能。这是我们团队捕获狭窄空间的唯一选择,挑战是保持安全性,准确性和范围。”

使用的RM调查Leica Cyclone寄存器360后处理办公软件以注册和清洁最终扫描数据。Leica Cloudworxwas used to work efficiently with the point clouds directly inside AutoCAD for the 3D modelling of the timber structures.

除了导航狭窄空间之外,另一个挑战是很难在屋顶上获得调查控制。成为遗产建筑意味着团队无法切割或进行任何屋顶穿透。

The team resolved this by usingLeica Cyclonecloud-to-cloud registration of the point cloud. Due to the confined nature of the roof spaces, survey control could only be placed at the access and egress points to the “crawl” spaces. For the elongated roof spaces, the team could remove a couple of tiles at the far end and shoot control from the street. This was to ensure the accuracy of the dataset, primarily the orientation, as the team moved down space (cloud-to-cloud can drift the orientation out).

新的西澳大利亚博物馆于11月21日(星期六)向公众开放,并提供了新的建筑物和新名称:WA博物馆Boola Bardip。该博物馆是由Multiplex和Hassell + Oma设计和建造的,最近入围了澳大利亚建筑成就奖。
