PROJECT：在德国Elbe隧道中快速安全的运动学现实捕获亚博ag真人规律
CUSTOMER: dhp:i
PRODUCT: Leica ProScan
OBJECTIVE: Documentation the three older tunnel tubes by kinematic 3D laser scanning to create current, accurate inventory documentation available to the Elbe Tunnel operator.

One of the most important components of northern Europe’s infrastructure lies about 28 metres (92 feet) below the surface of the Elbe River: the Elbe Tunnel in Hamburg. As part of the A7 Autobahn, it connects the southern and northern portions of the Hanseatic city of Hamburg and the Scandinavian countries with Europe’s metropolises. It is about 3.3 kilometres (1.9 miles) in length, with some 1,000 metres (3,280 feet) passing under the riverbed. At peak periods, up to 145,000 cars and trucks pass through the tunnel’s four tubes each day.

这三个较旧的隧道试管被运动学3D激光扫描捕获，以为Elbe Tunnel Operator创建当前，准确的库存文档。以前无法实现，没有大幅破坏，Leica Proscan在紧密的通道限制内，可以在地下环境中快速准确地映射。

下载完整的案例研究以获取更多信息

To ensure the future safety of this important traffic route, the three older tunnel tubes were renovated between 2009 and 2013 in accordance with the updated guidelines for facilities and operations of highway tunnels. The state geoinformation and survey office commissioned the Hamburg based company Dr. Hesse und Partner Ingenieure (dhp:i) with the documentation of every tunnel tube by kinematic 3D laser scanning.

Enabling accurate inventory documentation

目的是使Elbe Tunnel Operator可以使用当前，准确的库存文档。需要获得的地理参考信息，以维护和维修支持ELBE隧道规划，设计，施工和管理过程，以及作为未来建筑信息建模（BIM）的基础，以及其他用途。

启用有效的资产收集

In addition to the tunnel geometry, all other objects and equipment in the tunnel also had to be recorded for this purpose within an accuracy of a few centimetres. The assets included emergency exits, phones and operation alcoves, escape route signage, fire protection systems, ventilation shafts, lighting systems, cameras, amongst others, totalling more than 200 different 3D objects.
