Laser scan – 360 panoramic views

The solution was to “bring” the existing Central Bus Station to the office making it accessible to the team in their computers.

Background Information / Main Objective

The solution was to “bring” the existing CBS to the office making it accessible to the team in their computers.
3D Scanner Technology is based in the ultra-quick survey of millions of points. The result is a point-cloud of the reality around the instrument. This point-cloud is similar to a panoramic 3D picture where every pixel has coordinates.
3D Scanner Technology is not an innovation at Heathrow, it has been used for different purposes like surveys and as-build records. The FAUK team decided to give it a different uses for the replacement of the Inflatable Roof of the CBS:
 Base document for the Dilapidation Survey of the existing building before starting the works.
 360 panoramic views of the interior of the building in order to:
o Understand the building and its constraints
o Take accurate measures (each pixel has coordinates) without the need to actually going into the facility.
A laser scan of the existing building was made before the works started on site and another one after the completion of the works. These two point-clouds helped us compare the “before2 and “after” of the works.
The 360 panoramic views were accessible to the team in their computers via a free web based software that runs on Internet Explorer. The software used was TruView from Leica Geosystem.
TruView Software:
 Homepage: a 3D view/map of the building with symbols (yellow triangle) which indicate where each survey/panoramic view has been taken
 Clicking in one of the symbols, will take you to the specific view
 Once in the view, different tools are available like measures, checking coordinates and annotations
 From one of the views, you can move to the next ones
 It looks like a Google Street view of the interior of the building where you can wander around.
