Photogrammetry is the process used to create the 3D scan of an object, using multiple images. By combining a lot of pictures, you will be able to create a three-dimensional image. Photogrammetry works by extracting the geometric information of a two-dimensional image. This is the method used to turn several pictures into an accurate 3D design. If we take a look back at the history of photogrammetry, we can see that the first experiments of projective geometry are not that new! Indeed, back in 1480, Leonardo Da Vinci was trying to determine the painter’s eye point from perspective painting. Indeed, this process collects the data regarding the shape, the volume, and the depth of the subject that you are trying to scan.

It is imitating the stereoscopy of the binocular human vision, and it is actually used to get all the information of existing physical objects.

Photogrammetry can be used to record complex 2D and 3D motion fields. This method is using the parallax obtained between several pictures, taken from different points of view.

Photogrammetry is a science of making a measurement from photographs.
