Photogrammetry

Photogrammetry is a non-contact measurement technique that derives accurate 3D geometry and spatial dimensions from sets of overlapping 2D photographs. In veterinary science it is used to obtain body measurements, wound areas, limb morphology, and anatomical volumes from live animals, carcasses, or skeletal specimens without physical restraint or invasive procedures. Structure-from-Motion (SfM) algorithms have made the method accessible to field and clinic settings using consumer-grade cameras.
