Lynx Drones produce 3D model and architectural plans for Fosters Bakery

Lynx Drones teamed up with Barnsley based Fosters Bakery to produce a 3D model, architectural plans, and Digital Terrain Model (DTM) of the site. The exterior data was collected using our Yuneec H520, flying in a grid-like pattern to collect over 500 images of the site. We achieved a Ground Sample Distance (GSD) of 1.3 cm/pixel. The fly-through video of the Fosters Bakery exterior point cloud highlights the level of detail we can achieve. We also produced DTM with a resolution of 5 cm from the same set of images to allow the client to analyse the elevation changes present on site.

To produce a 3D model of the inside of the bakery required the use of a fisheye lens and DSLR camera. This was deemed to be the least invasive method of data capture, requiring zero downtime in the bakery’s production. Almost 2,000 images were taken inside the ~25,000 sq ft factory bakery. The fisheye lens allows us to greatly increase our field of view and therefore increases the amount of vital overlap between images needed to produce the model. 

Almost 50 hours of processing time were required to process the images room by room and tie the rooms together. The resulting densified point cloud was then imported into AutoCAD so that the walls, doors and stairs could be drawn for the architectural plans.
