What is Photogrammetry?

What is Photogrammetry? Photogrammetry is a technique or a method of distance measurement, by which distances between captured data features are measured.

The measurement process is done through the use of Cameras and its quality depends on the quantity of photos taken. The quality of feature matching and alignment process can depend and can be improved by better quality camera sensors and lenses. Depending on the degree of overlap of each photo with one of its neighbours, parallax and displacement of each datapoint in space is calculated.

Photogrammetry relies heavily on the uniqueness of each neighbouring pixel for the calculated 3D shape to be accurate. The software of choice for most 3D Capture and 3D Scan Processing studios is Agisoft Photoscan.
