3D Scanning
What is Photogrammetry?
Photogrammetry is the technique of extracting 3D information from photographs. The process involves taking overlapping photographs of an object, structure or space and converting them into 3D digital models. These models can then be used for a variety of purposes from viewing on the web, interacting within a game engine, 3D printing and preservation.
Strengths & Weaknesses
Strengths: Cost-effective hardware, highly accurate, colour information, images can be re-processed, swappable lens for large range of object sizes
Weaknessess: Can’t scan highly reflective or black surfaces, relies on specialist knowledge, time-consuming to capture and process

This study pioneers a new computational approach for the study of changes in shape of objects across time. Previously, such investigations were undertaken by scholars using a purely visual approach and relied on images of objects or in-person observations.
