战斗时间和潮汐，以平价为3D的5公顷沿海建筑工地

In 2018 the construction of Hyosung Vina Chemicals Port began in the Ba Ria-VungTau province, southern Vietnam. A collaboration between the Vietnamese Government and South Korean industrial conglomerate Hyosung Corporation, the new port is a part of the Hyosung Chemical Complex. Once completed, the Hyosung Chemical Complex will include a propane dehydrogenation (PDH) production plant, a polypropylene (PP) plant, a liquefied petroleum gas (LPG) storage tank and an LPG and petrochemical product warehouse in the Cai Mep Industrial Zone in Ba Ria-Vung Tau, located near Ho Chi Minh City.

该开发项目的最后一项任务之一是港口的液化石油气码头的建造。在海洋，水路和运输基础设施中拥有30多年的经验，Portcoast是越南领先的港口和沿海调查顾问。该公司致力于为地形调查，液化石油气码头和设施制造的型号制作3D映射，并为保护码头的护理报告进行检查报告。

地形调查覆盖了超过5公顷的区域 - Portcoast的专业知识和经验水平在水中，对于在这些难以到达的地区收集数据至关重要。为了加剧无法获得的挑战，尽管该综合大楼的某些地区仍在建设中，但其他地区已经在运作。

该项目的Portcoast团队负责人Hoang Hiep博士评论了“The main challenge for scanning the whole port was the selection of scanning positions in a complex where there was significant traffic and where disturbances from the ongoing construction work could compromise the stability required for precision scanning.”

为了减轻在这种破坏性，交通繁忙的环境中工作的挑战，Portcoast决定从内部道路上方的高架位置进行扫描。

Portcoast的Hoang Hiep博士解释说，“从高处上方工作需要一个扫描仪，该扫描仪可以在长时间可测量的范围内提供高度的精度。Leica ScanStation P50的精度最高为3mm，因此我们可以自信和精确地覆盖整个范围。”

Whilst theScanStation P50被用来捕获桥顶上的数据，在团队使用特殊修改的设备的桥下，例如定制的起重机来安装Leica RTC360和Leica BLK360在复合物，狭窄且无法接近的区域中测量和捕获高度详细的数据，例如液体罐，管道系统，进入桥和海洋装载臂。

时间就是金钱

承诺为该地区提供巨大的经济利益，据估计，该项目在建设过程中就为大约2,000名工人创造了就业机会。一旦完成，该港口估计每年为州预算贡献8000万美元，因此必须确保港口能够尽快完全运行。因此，速度是选择Portcoast设备和培训团队使用此设备的关键因素。

“Not only was the training time for the team almost halved by working with the Leica Geosystems team, but the high speed of capturing data with Leica’s equipment significantly reduced the survey time. In a project like this, the topographic survey of revetment would usually take around 12 hours with a survey grid of 20m per setup. Whereas it can be reduced to 3 hours when using the ScanStation P50. Accelerating the process also reduced our operational risk and the number of employees required for this work,”Hoang Hiep博士解释说。

加强网站和数据分析办公室之间的协作

为了扫描端口，Portcoast需要结合数千点并将来自不同设备的数据组合，例如总站，GNSS和激光扫描仪 - 通常证明这是一个非常复杂且耗时的过程。亚博5分钟快三Leica Geosystems的设备和软件解决方案的无缝集成意味着可以在处理数据和现场团队的异地团队之间很容易传递数据。

Having worked in similar projects across Southeast Asia, Pakistan and U.A.E, Portcoast were particularly conscious of the importance of fast data transfer in tropical countries. The rapidly changing weather conditions demand fast data transfer between field and office teams to verify data and prevent any loss of data. After collecting the point cloud data from the geodetic equipment, Portcoast used the狮子旋风,Leica Cyclone 3dr和Leica Infinity非现场处理数据。

“The high-speed and high-level accuracy of capturing field data helped to avoid delays in office post-processing as the software helped us to check the points every time we needed to. With Infinity and ConX it is easy to transfer data between the field and the office within 1 min,”Hoang Hiep博士补充说。

“旋风产生的结果图是一个非常准确的模型，我们可以用来创建3D模型和VR系统。然后，我们可以进一步完善模型以提供高水平的准确性和可见性。”

By collecting point cloud data at different times and usingLeica Cloudworx for Revit为了将其转换为井井有条的图纸，可以以最高的精度估算用于沉降或位移的边距（毫米）。

截至建造的图纸和BIM将支持港口的设施管理方面，为检查报告提供参考，并使Hyosung使用数字模型计划和模拟港口的未来发展和翻新。

仅仅几周才能完成的七名工程师团队的工作将大大减少将来维护所需的现场访问，并可用于增强和保护未来几十年的港口运营。

“当我们接受这个项目时，只有一半的团队在这种地球设备上都有任何经验。整个Leica Geosystems产品生态系统的集成效率提高了，节省了相当大的时间，现在整个团队都渴望定期使用Leica Geosystems Geodetic设备” concluded Dr. Hoang Hiep.
