The Real Deal pays out

Author: Katherine Lehmuller, May 2016

3D激光扫描仪是大投资，Westland Group，Inc。于2000年在加利福尼亚州兰乔库卡蒙加（Rancho Cucamonga）成立，美国花了很多年来寻找合适的乐器。公司有一定的需求；他们为铁路所做的工作，通常要求在隧道和桥梁周围进行清除调查，理想情况下适合点云和基于云的模型。

Westland收到Leica Nova MS50多站后一个月，他们的一名客户J.L. Patterson＆Associates（JLP）是一家铁路专业工程公司，来到了Westland，并要求进行移动LIDAR调查的地面控制。JLP的3D地理空间数据的先进用户希望Westland沿着墨西哥边境附近的几条铁路隧道进行控制，而其他人则在做激光雷达工作。JLP习惯于与Point Clouds合作，但在3D激光扫描时不一定会想到Westland。Westland建议他们不仅提供控制权，还提供一条隧道，看看可交付的隧道是否有效，并且对JLP具有成本效益。要约被接受，韦斯特兰开始工作。

太平洋统帅权的最终可交付成果l Railroad (PIR) on a section of rail known as “The Impossible Railroad.” PIR is rehabilitating the Impossible Railroad for use with double stacked trains, and 17 tunnels will have to be surveyed for clearance analysis and possible grading and track redesign. WestLAND saw the scan of one tunnel as basically a marketing investment and offered to scan one of the smaller tunnels, No. 15, which was only 91.4 metres long. It was the first project to make use of the MultiStation and it went very well.

While traversing the tunnel with the MultiStation for the control survey, the equipment was switched to scan mode and after a few setups, immediately started scanning. The entire tunnel took only a few more hours to scan and also gave the engineers time to clean up notes and sketches, and take pictures of the site to supplement the MultiStation’s images.
