Photogrammetry

the science of making measurements from photographs

Photogrammetry

how to scan

When scanning a free-standing object, encircle it, then focus on more complex details.

Aim for at least 60% overlap between photos.

Your object fills the camera view

Your white balance fixed

Your object is fully in focus in every shot

(Use HDR if your object is unevenly lit)

make sure

things that don't work well

transparent things

reflective things

complex shapes with thin extensions
