Over the last semester, EdTech hired a student, Keegan Millbern '19, to create 3D images of academic buildings on the Lewis & Clark campus. Keegan spoke of his interest in a technique called Photogrammetry which uses everyday photos of an object to create a 3D file that may be rotated and viewed from all angles.
The first trick is taking photos of a building from all angles--that means above the building and the upper stories. To accomplish this, drone photography is ideal. Because a good, modern drone has GPS sensors to keep it stationary, all that needs doing is to fly the drone at a chosen elevation and take hundreds of photos, change elevation and take even more photos!
The photos are then loaded into software called Agisoft Photoscan, which compiles the photos into a rough 3D representation of the building. Ok, so there's quite a bit of refinement and massaging that happens, but eventually you end up with the 3D model of the building.
Keegan has completed several models so far and will continue working on them through the spring. We in EdTech hope to use the models as part of a repository of digital assets that could be used for future projects involving Virtual/Augmented Reality tours, or simulations of natural disasters, or even campus facilities planning needs.
