Photogrammetry is now possible using consumer devices, and the applications are vast.
Continuing improvement in digital cameras—including those in cell phones—and in photogrammetry algorithms have enabled dozens of consumer and professional photogrammetric applications. Among the professional ones is PhotoModeler, which produces accurate maps, drawings, CAD data, 3D models, and photos draped on 3D models.
Its applications include engineering, surveying, architecture, industrial measurement, manufacturing, accident reconstruction, forensics, gaming, and animation.
A user takes photos of an object—say, a fire hydrant, a boat, or a house—from different positions and angles, loads them into PhotoModeler on a computer, and chooses a processing method.
