Why use photogrammetry?

Field work that used to take many days, can now be performed in hours

What is photogrammetry?

Light rays from a given point of an object reaching the surface of the camera film (or surface of the digital imaging chip or your eyeball) creates a two-dimensional image.

Each point could have come from a number of different points along a line between the object and the camera sensor.

How does photogrammetry work?

Photogrammetry uses images from two different locations to determine the 3rd dimension, or depth and the location of a particular point.Diagram showing data points for 3D photogrammetry
