Photogrammetry is the process of extracting measurements, maps, or 3D models from photographs, usually by comparing many overlapping images of the same object, structure, or landscape. In archaeology, it is widely used to document excavation units, standing architecture, artifacts, and entire sites with drones, handheld cameras, or fixed rigs.
How AI Helps Photogrammetry
AI can help photogrammetry by improving feature matching, classifying scene elements, cleaning point clouds, segmenting structures, and speeding up the path from raw imagery to usable models. It often works alongside computer vision, digital twins, and digitization. The practical value is usually better documentation quality and faster processing, not magic reconstruction from poor image capture.
Why It Matters
Photogrammetry matters because it turns ordinary photography into a measurable archaeological record. That makes it much easier to preserve excavation context, compare features over time, share evidence across teams, and revisit fragile or distant material without handling it repeatedly. The method is powerful, but its quality still depends on image overlap, scale control, lighting, calibration, and careful field practice.
Where You See It
Photogrammetry appears in archaeology, architecture, heritage conservation, construction, surveying, and environmental mapping. In archaeological work, it is especially valuable for trench documentation, artifact modeling, site reconstruction, and public interpretation.
