The Grand Cathedral Square building - 3D Laser scanned

This is how an Iconic heritage building during the restoration phase looks like when 3D is scanned and visualised in an x-ray mode. In this case, we have 3D scanned the Grand Cathedral Square building in Christchurch, by utilizing both terrestrial, aerial scanning and also photogrammetry. 

This project has multiple stages. 

First Stage: In the first stage, we have 3D scanned the building internally with a @matterport 360 Spatial Imager and created an Interactive 3D Virtual tour, showcasing the entire interior of both levels and the Tower. The Tour can be viewed by clicking on the following link: The Grand Cathedral Square - 3D Virtual Tour

Second stage: In the second stage, we have focused on collecting more sophisticated spatial data for 3D Pointcloud, by scanning the building inside-out on the ground from 99 different scan locations with a Leica 3D laser scanner. The 99 scan points totalled 4.3 billion points with XYZ coordinates and relative space to each other in an impressive complete point cloud. Below you can see a quick animation showcasing just the data captured internally. Attached is also one photo capturing the fused data captured both internally so as externally. 

Third Stage: To be able to replicate this iconic building in high detail, we have collected over 600 20MPX photos with a drone and over 100 38MpX photos with a Nikon D610 capturing the building externally to its finest details. The collected data was further processed by using photogrammetry. The Results will be published soon 

Fourth Stage: this is the final stage where we have used the collected data to create realistic renderings for light simulations of how the Grand Cathedral Square building will look like when finished in late 2022.
