A 320-gigapixel image of London taken from the top of the BT Tower has set a new record for the world’s largest panoramic photo. The picture, which is made up of 48,640 individual images, shows a full 360 degree view of London in incredible detail. To capture the source frames, 4 Canon EOS 7D cameras with EF 400mm f/2.8L IS II USM lenses and Extender EF 2x III teleconverters were mounted on Clauss company Rodeon VR Head ST robotic panorama heads and positioned in four secure locations around the 29th floor platform. The raw images were then processed over a multi-week period using Fujitsu Technology Solutions’ Celsius R920 workstation with 256GB of RAM and 16 cores at 3.1GHz, and Autopano Giga panorama stitching software from Kolor. The project was commissioned and financed by the BT Group, and completed by 360Cities.
