Photogrammetry is the science of making measurements from photographs. It infers the geometry of a scene from a set of unordered photographs or videos. Photography is the projection of a 3D scene onto a 2D plane, losing depth information. The goal of photogrammetry is to reverse this process.
La photogrammétrie est une technique qui consiste à effectuer des mesures dans une scène, en utilisant la parallaxe obtenue entre des images acquises selon des points de vue différents. (Wikipedia, CC BY-SA)
