Scans, spans and automobiles

作者：克里斯托弗·多拉德（Christopher Dollard）

As part of Northern Ireland’s ‘Building a Better Future’ strategy to make it a better place to ‘live, work, learn and grow’, Amey Roads NI (ARNI) was tasked with building, operating and delivering improvements to a strategic road network across Northern Ireland (DBFO Package 2). But managing such acomplex infrastructure面临着挑战 - 从昂贵的道路封锁到解释1960年代的手绘。阿尼（Arni）的工作切断了，所以它转向了latest reality capture technology,Leica BLK360, to create accurate3D点云和图片of the projects.

道路基础设施管理的复杂性

阿尼负责540 lane-kilometres of motorway and trunk road,140个桥梁和ancillary structures. The company employs Amey Consulting to manage the lifecycle risk profile of new and existing highway assets, and to完成桥梁的完整调查计划基本的维修和改进工作，并作为常规检查计划的一部分。所有这些都始终保持道路开放，结构始终运转 - 绝非易事。任何封路不仅会花费公司的钱，而且还会花费大量冗长的计划，更不用说中断交通流量了。

BLK360成像激光扫描仪旨在特别解决此类挑战。Arni获得了BLK360并开始survey the bridges, create reference models和确切的3D扫描支持补救工作和定期安全检查。使用直观的激光扫描仪及其iPad软件Recap Pro，调查桥成为一个简单得多的过程。一个工人可以安全地停在高速公路的硬肩上，并在按下按钮, scan the entire underside of the bridge,确保详细的360度,HDR spherical imagery and accurate point clouds在几分钟内。

扫描提供3D点云, images of the bridges and its surroundings, and scan annotations highlight concrete delamination and exposed reinforcement. This helps to快速确定缺陷的确切位置和性质或失修的领域，而不是需要interpret site notes,sketches和图片。Design teams use the point cloud in Civil 3D tocreate surfaces,海拔和section drawings和计划维修工作 - 包括需要哪些零件，材料和资源 - 更有效。一旦维修工作完成，重复扫描就可以为健康和安全文件生成完整的备受制作的记录，并可用于证实工作的完成并授权付款。

无路可退

使用BLK360，Arni现在可以对高速公路桥进行及时，准确的调查和检查。对于日常使用，BLK360非常便携，并且Recap Pro iPad软件非常user friendly。与传统的调查相比，它产生highly detailed and accurate datawithin each scan.

ARNI recognised that the BLK360 would quickly return a sizable cost saving against the initial outlay. For example, previously, it could cost up to 4,000 British pounds (4,456 euros) to arrange a total road closure needed to complete a full bridge survey – and, over140个桥梁, that soon adds up. Using the BLK360 allows ARNI to quickly capture all essential data accurately, and without the need for costly and disruptive road closures and traffic management. It also makes it safer for surveyors who can now do their job from the hard shoulder or behind the safety barrier, removing the need to stand in the middle of the road.

The depth of detail captured by the BLK360 surpasses anything ARNI was able to capture previously. The scans are passed to designers, allowing them to immediately see where remedial work is needed, rather than having to interpret different plans, drawings and notes.“Gone are the days of handwritten notes and zoomed in photographs that no-one can figure what part of the structure we are looking at!”said John Jordan, lifecycle project manager at Amey Roads NI.“BLK360已经证明自己是一个中国al part of our team, and we look forward to continue exploring the possibilities of the BLK360 and identifying new ways it can transform our work, create efficiencies and reduce costs.”

Jordan was awarded the company’s Amey Consulting Award in the ‘Putting People First’ category for his 2018 work with the BLK360. This specific category recognises individuals, teams or projects that have demonstrated the greatest impact on overall employee safety and wellbeing.“The use of the BLK360 technology helped remove surveyors from harm's way on a number of risky jobs, including the DBFO2 work on the motorway,”said Jordan.
