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. The dense modeling of the scene is the result yielded by chaining two computer vision-based pipelines: \u201cStructure-from-Motion\u201d (SfM) and \u201cMulti View Stereo\u201d (MVS).&#8221;<\/p>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n","protected":false},"excerpt":{"rendered":"<div class=\"entry-summary\">\nPHOTOGRAMMETRY It all starts by taking a lot of photos. 3D models can be made from a series of photos with a technique called Photogrammetry.
