Intro to Photogrammetry
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)
