SWISS geomatic and surveying equipment specialist Leica Geosystems have released a video showcasing the 3D laser scanning of a new BMW assembly plant in
The factory, in San Luis Potosi, has a surface area of 70,000 square metres (753,000 square feet) and will begin operations in 2019 with the goal of becoming BMW's most resource-efficient plant.

With rapid changes in the automotive industry, production and assembly lines are being increasingly re-tooled.
Embarking on refurbishment and upgrade projects, leading automotive manufacturers are demanding reliable information about their current production facilities. Highly accurate 3D laser scans - that capture millions of points of data to accurately map existing sites and buildings into three dimensional digital models (known as "point clouds") - can improve project planning and help to avoid costly mistakes during refurbishment works.
Any delays can increase downtime, affecting BMW's production timescales and output.

BMW's newest plant was documented in just under an hour and 20 minutes using a state-of-the-art back-mounted scanning system. Conventional surveying techniques would have taken several days and could easily have delivered a lower level of accuracy.

Simultaneous Localisation and Mapping (SLAM) correction was applied to the initial point cloud survey for a more accurate result.
The processing time of this initial data set was under two hours, after which an information model was created.

The resulting point cloud survey and information model effectively provided a "digital twin" of the BMW facility at 3-7 centimetres accuracy, which is accurate enough as a base for future modifications.
