3D scanning
Photogrammetry
The science of making measurements from photographs
Using software to construct 3D models from sets of photographs (or video frames)
Structure from Motion
Photogrammetry
recognizes key points
shared across a set of images
and reconstructs
their 3D position

Capturing Scenarios
object
facade / wall
room
Fixed zoom level
Fixed white balance
Fill the frame
Fully in focus
Evenly lit
Camera settings
Ensure at least 1/3 overlap
Approx 30 - 50 photos gives decent results
Think: photos as data
Avoid blind spots
