• Know how photogrammetry works. It uses optics, the study and behavior of light, combined with projective geometry to determine points on an object. The distance between these points are then estimated and a 3D digitized model is created. • Stereophotogrammetry is slightly more complex than photogrammetry and utilizes two photographs taken from different angles to estimate intersecting coordinates. With these estimates known, it is possible to create a 3D measurement of an object with the two photos. • For the most accurate results, photogrammetric data is combined with range data from 3D laser scanners or white-light digitizers. This is because photogrammetry is extremely accurate measuring the X and Y axis’ of a coordinate plane, while 3D laser scanners and white-light scanners are more accurate in the Z axis range. Learn about the different possible uses for photogrammetry. There are many different trades and professions that utilize photogrammetry and stereogrammetry. • In enginee
