Photogrammetry
AI & Emerging Tech
Building a 3D model from many overlapping photographs of the same object.
In practice
Photogrammetry reconstructs geometry and texture by finding the same points across hundreds of photographs taken from different angles and triangulating their positions. It is how physical masters become digital collectibles, how film sets become game environments, and the most accessible route to a faithful 3D scan — a phone and patience will do.
Questions
What is Photogrammetry?
Photogrammetry is measuring and reconstructing a 3D object from overlapping photographs, producing a textured mesh that matches the original.
Why do you use Photogrammetry?
It captures the actual surface — every scratch, grain and fingerprint — where hand-modelling would idealise it away. Fidelity is the point.
How do you use/apply Photogrammetry?
Shoot the object from every angle with heavy overlap and even light, avoid reflective or transparent surfaces, process in reconstruction software, then retopologise and clean.
When do you use Photogrammetry?
For real objects you need digitised faithfully — products, artefacts, sculptures, terrain. Not for shiny, clear or moving subjects, which defeat it.
Who uses Photogrammetry?
Industrial designers, archivists, game and film artists, and anyone turning atoms into bits.
