Photogrammetry Sept 2025

3D Imaging for Cultural Heritage

(short URL: https://tinyurl.com/emkp3d)

Thursday September 11, 2025. 14:00–17:00. Senate House MakerSpace.

This session will introduce the practice of photogrammetry, a 3D method suitable for capturing full 3D geometry and photographic surface colour using any digital camera (including a phone camera). Participants will have the opportunity to practice the photographic techniques required to model an object in the round, and to try out processing the photographs using Agisoft Metashape Professional software. We will also give you pointers toward some more advanced features such as aligning two partial 3D scans to make a complete model, editing and post-processing your model, preparing your model for 3D printing, and uploading to a 3D viewing platform such as Sketchfab.

Optional:

• If you would like to install the software on your own laptops in advance (or after) the session, we recommend a free 30-trial license for Agisoft Metashape (the most widely used and user-friendly photogrammetry software): https://www.agisoftmetashape.com/downloads/. This trial is for 30 days so please do not activate the trial too far in advance of the workshop.
• If you want to upload 3D models, you may like to create a free account on Sketchfab in advance: https://sketchfab.com/

• Where can I find a 3D printer?
• What are my options if I have an object that is not suitable for photogrammetric imaging, according to your advice?
