We are only seeking Man. We have no need of other worlds. We need mirrors. We don't know what to do with other worlds. A single world, our own, suffices us; but we can't accept it for what it is.

Pareidolia

the tendency to interpret a vague stimulus as something known to the observer, such as seeing shapes in clouds, seeing faces in inanimate objects or abstract patterns, or hearing hidden messages in music.

Reality & Representation

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

Accessibility

Affordability

Accuracy

Photogrammetry  vs

other techniques

⭐️⭐️⭐️⭐️⭐️

(e.g. Laser)

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

Photos

hard to scan...

transparent things

reflective
things

thin
parts

comparisons = combinations
