PhotoModeler is a software application that performs image-based modeling and close range stereophotogrammetry – producing 3D models and measurements from photography. The software is used for close-range, aerial and uav photogrammetry.

Close Range Photogrammetry (CRP) can mean photographs taken from the ground with a handheld camera, or taken from a UAV/drone at relatively low altitude. PhotoModeler and CRP are used for performing measurement and modeling in agriculture, archaeology, architecture, biology, engineering, fabrication, film production, forensics, mining, stockpile volumes, etc
