通过测量和激光扫描技术在越南留下遗产

Phu My Port is a general cargo port located in Ba Ria-Vung Tau, Southern Vietnam. Operating since 1993, the port aims to offer a fast, effective and reliable port services available to customers 24 hours a day all year long. When the owners faced challenges in obtaining complete data documentation for the port, Portcoast recommended applying a technique they had used previously: laser scanning to collect data in order to develop a 3D BIM model of the port. The port’s owner commissioned an inspection report for the 132-metre main berth and 72-metre-long access bridge, along with 3D laser scanning of the whole Phu My Port, including yard, warehouses and facilities. By scanning the port and its facilities, the goal was to provide the owners with a digital twin of the whole site for ongoing inspection and maintenance.

的发票estors in this project were keen to ensure the laser scanning was conducted with the highest levels of accuracy by an experienced team who could categorically verify that the digital twin was correct.

Portcoast is one of the most experienced surveyors of marine, waterway and transport infrastructure sites in the region. With a reputation for accuracy, they have a proven track record in carrying out similar projects in the region, such as the 3D scanning of the nearbyHyosung Vina Chemicals Port，Posco SSVN港口及其工作Hutchison Ports SITV。In this project, surveyors from Portcoast were responsible for inspecting and scanning the whole port as well as providing quality assurance for the final 3D model.

团队选择了速度和范围的准确性，以及访问狭窄，具有挑战性的领域的能力，团队选择了合并的现实捕获解决方案，包括bob综合app赌博Leica ScanStation P50for the long-range scanning work, theLeica RTC360和Leica BLK360。对于地形调查，现场的测量师使用Leica Nova TS60，，，，Leica GS18T和Leica iCON iCR80大地设备。

由于其1公里的范围和1毫米的精度，ScanStation P50能够快速捕获详细的，准确的数据。同时，RTC360和BLK360激光扫描仪捕获了在泊位下占据的孤立且难以接近的区域，在该泊位上运行较大的三脚架安装的3D扫描仪是不可行的。这些较小的扫描仪的灵活性意味着可以将设备牢固地降低到位 - 捕获Hyosung Vina Chemicals端口时先前尝试和测试的技术。

虚拟现场访问

With a total area spanning around 30 hectares, the team needed to scan from approximately a hundred positions, combine the data and transfer it quickly from field to office. Rapid capture and transfer of data was imperative in the unpredictable and ever-changing tropical climate of the region.

根据他们以前与技术合作的经验，Portcoast再次选择了Leica Infinity和狮子旋风办公软件充当站点和办公室之间的数字桥梁。只需一秒钟即可传输现场和办公室的数据，团队可以实时查看数据，与现场团队同步工作。

Dr. Hoang Hiep of Portcoast explained,“ Leica GeoSystems设备可以帮助我们避免延迟现场数据处理以及使用Leica Geosystems的软件，我们可以在每次需要时检查这些点。有了新的总站和GNSS设备 - 田野和办公室之间的流程是无缝的，帮助工程师减少了两个地方之间的时间。数据的高速和准确性是Leica Geosystems的设备是我们的首选。”

使用数据，PortCoast为整个端口构建了点云模型，将每个元素中的所有信息都包含到BIM模型中。数据捕获的准确性意味着用户可以通过VR/AR体验项目。该团队能够在位置进行质量检查，以检查详细信息，例如使用点云在泊位下桩的垂直轴周围的倾斜度和旋转角度。由于模型的精确度，客户和现场主管现在可以监视所有调查数据，而无需访问建筑工地。

建立遗产

数字双胞胎不仅会继续在未来增加价值，而且在进行这项工作时，团队还在越南建立了专业知识的遗产。Portcoast的开创性方法意味着，诸如Leica Nova TS60，Leica GS18 T，Leica Icon ICR80等新的Leica Geosystems设备首次在越南和东南亚首次使用。

使用这些设备的实践经验将在将来在类似项目上使用Portcoast的运营风险，Portcoast还将通过更广泛的培训计划来传递他们的经验。

Dr. Hoang Hiep of Portcoast commented,“由于Leica Geosystems产品的耐用性和有效性，再加上Leica Geosystems的培训和支持，我们能够节省此类项目的人bob综合app下载力成本。在培训课程之后，我们开始使用设备，现在能够将此专业知识传递给其他人。我们正在培训整个团队，以确保公司中的每个人都能充分了解3D激光扫描。扫描和过程数据是我们在Portcoast日常工作的一部分。”
