Photogrammetry

is the science of making measurements from photographs

Photogrammetry

reconstructs 3D points and shapes
based on shared features amongst a set of images

When taking photos, your object needs to be always in view.

object

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

When photographing make sure that:

  • Your white balance is set manually
  • Your exposure is fixed
  • Your subject is in focus in every shot
  • As much of the scene as possible is in focus (avoid zooming / shallow dept of field)
  • If possible, enable HDR, mainly if your object is partly in shade

Please capture:

  • 3 small objects (smaller than a laptop)
  • 2 bigger objects (bigger than a laptop)
